while the developers and miners still haven’t found a way forward , this brings us to the third , and most important group in the game theory of bitcoin : the users . this group has the ultimate control in bitcoin . if bitcoin split into two coins , the users would determine which one is the “real” bitcoin simply by choosing to hold and transact more with one of them , thereby boosting its price . however , the bitcoin developers and miners have no way of determining in advance which version of the coin users would support . while one might say that the 20 . 5 million wallets represented by the companies who signed the new york agreement represent a significant percentage , for now , some users who support the core developers and are angry that bitmain has thwarted the adoption of segwit are aiming to wrest control from the miners . they are attempting a “user - activated soft fork , ” a sort of declaration of war on the miners . a video about uasf that featured bitcoin “maximalist” tone vays — someone who believes that in the future , there will only be one dominant blockchain , and it will be bitcoin — begins with a shot of him standing in the woods wearing a flannel shirt and a camouflage uasf baseball hat , a bitcoin bandana masking his face except his eyes , his arms crossed over his chest and a machete raised in one hand and an axe in the other . while more ideologically driven bitcoin users may support this idea , it’s not clear whether they will garner the support necessary to pull it off . it currently has only 22 % support from companies in the space and a deadline of august 1 .

you’re not the first to have a “difference of vision” for bitcoin’s direction . litecoin was created to offer a better payment experience . dogecoin was , likewise , lauded for its micropayment potential . why not just use an altcoin , instead of forking away from bitcoin ?

reducing our carbon footprint is one of our key considerations , given that the electricity requirements of our operations have significantly increased as their scale has expanded . it is because of this that bitcoin group has , where available , chosen to power its mining operations through the use of renewable energy . currently we generate up to 82 % of our hash rate from hydroelectricity in china and geothermal energy in iceland .

the bitcoin scaling discussion has been an ongoing ferocious debate that has lasted for years . now there are multiple conversations taking place discussing different ways to scale like using alternative implementations of bitcoin’s code , a user - activated soft fork , extension blocks , emergent consensus , and just recently barry silbert’s idea . the suggestion announced by silbert’s company the digital currency group ( dcg ) is an agreement based off of rsk’s chief scientist , sergio demian lerner’s segwit - 2mb proposal . furthermore , silbert claims to have backing from 56 companies and over 84 percent of hashrate support .
to understand what has escalated the two - and - a - half - year - long controversy into all - out war , one first needs a little background in the game theory of bitcoin , which i outlined in this previous article . as i wrote then , “the magic of bitcoin has been the ability for various players with opposing interests to engage in a system that has so far led to an optimal outcome for all of them . ” as one would expect , however , when groups with opposing interests have to interact with each other , tensions arise . while , in previous open source projects , parties with opposite aims could part ways , in bitcoin , neither wants to leave what has so far been a highly lucrative game for each of them . ( hear two long - time bitcoin players explain this in my podcast . ) while bitcoin has many constituencies , one of the most important are the developers , who are like the designers of the game . another crucial group are the entities that run the bitcoin network on their computers ( called miners ) who are sort of the operators of the game .
apart from myself and freetrader , bitprim has been helping . that is a company that ' s building infrastructure for bitcoin . bitcoin unlimited developers andrea “sickpig” suisani and antony zegers have been helping out with bitcoin cash as well . and like other open - source projects , we have a kernel of people that contribute on a regular basis and even more that add a patch or two or help us with a specific problem .
in a situation when cryptocurrencies become more and more widely used penetrating even more spheres of peoples’ lives than ever , it is important for them ( esp . for bitcoin , as gmo plans to deal bitcoin mining business ) to secure their reliability in order to further develop and spread .
we have a very different way of doing development than both bitcoin core and bitcoin unlimited , mostly derived from my work at facebook as well as llvm where i worked prior . we focus on doing many small incremental changes rather than fewer , bigger changes . this makes code review easier .
unlike bitcoin or ethereum there are no iota miners , but rather each connected device provides the cpu resources required to process transactions . bitcoin and ethereum process blocks on the blockchain in sequence , while tangle makes it happen in an instant manner and on a peer - to - peer basis .
bitcoin will revolutionise the world of finance because it has the potential to make the world of finance more accountable and cheaper to operate .
of note are the many issues discussed in public filings so far this year , including the application of existing laws to bitcoin financial instruments . for example , the sec is currently working with two separate exchanges competing to be the first to host a bitcoin exchange traded fund ( etf ) .
when a bitcoin transaction is performed , it will form part of the transaction ‘block’ . the chronological record of verified bitcoin transactions is known as the block chain . each block within the block chain has its own block chain algorithmic equation and by solving the block chain algorithmic equation , miners attach the block to the block chain . the block chain is hosted by an online peer - to - peer network and shared by all bitcoin users .

ledgerx , which plans to roll out bitcoin options first starting in the fall , may also make it easier for investors to short cryptocurrencies . while it isn’t the first to offer bitcoin options , ledgerx is the first to offer options regulated by the cftc . in 2015 , a san francisco - based bitcoin options trading platform derivabit , also known as coinflip , was asked to cease operations by the cftc in 2015 for failing to register with the agency .
i got a sponsorship from the bitcoin development grant to do my scaling research . this was mostly thanks to other research i’d done prior . i’m not funded to work on bitcoin abc specifically . that was not the original plan ; but sometimes you can ' t predict where things are going to lead .
because of the risks presented by bigger blocks , bitcoin core developers generally prefer to offload the day - to - day inexpensive stuff to layers built on top of the blockchain . does bitcoin cash have no plans to adopt segwit , or the lightning network , or other second - layer technologies at all ?
to help minimize redundant projects , members in every division of the sec coordinate behind the scenes . ( one of the group ' s goals is to learn about the emerging risks created by distributed ledger technology ) . the dltwg also coordinates cross - agency regulatory efforts with federal , state and local law enforcement .
the concept of moving scaling along and bolstering a compromise . one bitcoin developer who has been a staunch supporter of the user activated solution , eric lombrozo ,
however , even though no core developers signed on , lombrozo said a number of them have been working to make sure it’s not a disaster anyway . at the same time , he believes that the companies who teamed up with the miners but didn’t manage to get any core developers on board allied with the wrong group .
traditional banks may be rendered obsolete by bitcoin and blockchain technology , but the reality is that blockchain has the potential to do much more than just support cryptocurrencies .
still , for some people living internationally—like venezuelans plagued with a shortage of cash and those in china , where the government has restricted movement of capital outside of the country—bitcoin presents an attractive option to get ahold of cash , harvey said . its rising popularity in these countries are part of the reason behind bitcoin’s recent surge .

we believe for bitcoin businesses in the mining industry be taken seriously they need to first have the transparency , accountability and legitimacy of a listed company .
spencer bogart , head of research at blockchain capital , said bitcoin’s price could fall as much as 20 percent but that its long - term adoption will continue .
internet is democratising information , 3d printing is democratising manufacturing , bitcoin is democratising money . how ? as the worlds first and leading decentralised trust network , bitcoin is able to transfer power from banks ( incumbents ) to the people , and in the process help connect the billions of unbanked in the world to the global economy .
“liquidity dried up—no shorts , no sellers , which means a volatile little bubble formed quickly , ” peter smith , chief executive of bitcoin wallet blockchain , told cnbc .
those sudden ups and downs would be bad news for your portfolio . although bitcoin had a more than 100 % return on investment in 2016 , it’s also five times more volatile than the s & p 500 , said campbell harvey , a professor of finance at duke university , who described bitcoin as “an extremely risky investment . ”
australian exchange and payment processor coinjar began imposing gst on bitcoin sales from 3rd october , although it has stated that it supports changes to the current tax treatment guidelines .
bitcoin’s three - year long civil war may finally soon come to an end — but whether that will be a peaceful ending or a bitter breakup remains to be seen .
bitcoin core has a pretty clear and consistent policy : no contentious hard forks . without such a policy , don’t you see a cryptocurrency splitting into factions for each disagreement ?
but i want bitcoin to be a widely used electronic cash . a cryptocurrency that is used for day - to - day inexpensive stuff , as well as expensive purchases .
we talk a lot about digital economy , but still rely on paper money . since 2008 , though , there is a completely digital alternative to physical currencies — bitcoin .
even more foreboding is the fact that , even as new money flows into crypto assets , businesses are pivoting away from bitcoin to build on other blockchains . that means countless transactions that could be processed with bitcoin , pushing up its price , will now take place on other blockchains , instead boosting their prices . accelerating that trend is the fact that non - blockchain companies are now creating their own cryptocurrencies — but not on bitcoin . for instance , kik , which plans to launch a new cryptocurrency called kin , is building it on ethereum . the factors above combined with the full speculative frenzy in non - bitcoin tokens and the civil war in bitcoin finally pushed its market cap as a percentage of all cryptocurrencies below 50 % for the first time a few weeks ago ; for years it had been at 80 - 90 % . it hasn’t recovered since .
as for the impact the departure of this economic activity will have on bitcoin , it’s not clear . while on the face of it , it seems incongruous that bitcoin should be reaching all - time highs at the same time that the community is in a civil war with no end in sight , chris burniske , blockchain products lead at ark investment management , the first public fund manager to invest in bitcoin , says that the price is reflective of the problems the network is facing . “although bitcoin is hitting new highs , it is dropping precipitously in its dominance of the overall crypto asset markets , ” he says . “so on a relative basis it is underperforming the asset class . ”
i think that people will come to an agreement . the reason there is a split now , is because people have different ideas of where they want bitcoin to go . once blocks on bitcoin cash fill up , people will still want to go to the same place , so i ' m confident they ' ll stay in the same boat .
bitcoin industry insiders have issued an optimistic prediction for the cryptocurrency over the next few decades , suggesting it could be as widely used as the swiss franc or the australian dollar .
i see all these different proposals as the symptom of a fast moving environment . when i started bitcoin abc with freetrader , segwit2x and the uahf did not even exist yet .
so far , it looks like the blocks are going to be slow the first week until difficulty readjusts , then it should be good ,
he told bitcoin magazine .
in essence , iota does the job miners do with bitcoin - but for free . there is no transaction fee and why even the smallest micro - payments are now possible .
moreover , though cfpb has authority to amend regulations under the payments - focused electronic fund transfer act , it is questionable whether the act is relevant to bitcoin , hughes says .
asic took the step of issuing a specific media release about the stop order given the publicity around bitcoin group’s intention to list and the fact that , as no prospectus has yet been lodged , a media release was an effective way for asic to highlight its concerns to the market and the action it took . in the release , asic reminded the market that it expects companies to be mindful of their obligations regarding pre - lodgment advertising and that asic will take action it deems necessary to ensure that investment decisions by the public are made in a fully informed environment .

some dedicated flashes ( e . g . nissin di - 622 and di - 466 ( canon and nikon dedicated versions ) , sunpak pz42x and pz30 , sigma ef - 530 / 500 dg st for canon , etc . ) are triggered via system - specific pins instead of the central contact of the hot shoe . cactus v5 does not work with these flash models . to check whether your dedicated flash units are compatible with cactus v5 , try attaching them to a camera of other brand ( e . g . attaching a nikon ttl flash to a canon dslr camera ) . if the flash can be triggered , it will work with cactus v5 .

during testing i found that the cactus v6 misfired a couple of times , but this is quite normal with remote flash triggers .
there are a number of reasons why you would want to use off - camera lighting .
using a remote camera lets you explore creativity and expand photographic coverage in unique way . .
whether you prefer canon , nikon or fujifilm , our selection of shutter release and flash sync cables allow you to connect cactus products with portable flashes , studio strobes and cameras so that you can trigger your camera or flash remotely . in essence , the cable allows your camera and lighting equipment to flash with shutter release at exactly the right time . but , cables may restrict movement and present a trip hazard , particularly when using off - camera flash at weddings where guests are , rightfully so , more focused on the bride and groom than the cables on the floor . with that in mind , laser and wireless triggers offer greater mobility .
you could use your sony camera with a adapter on it that has center pin passthrough , and use canon , nikon or pentax flashes off camera and remotely control the power with those .
i currently use the previous version of the cactus v6 triggers along with two cactus rf60 ( nikon sb800 and nikon sb80dx ) flashes , but i really wanted to try out the high - speed sync ( hss ) functionality of the new cactus v6 mark ii for myself , so i cycled over to outdoorphoto ( which was quite the distance ) to pick up the shiny new toys for this review .
ttl pass - through dual hot shoe design allows automatic exposures for on - camera fill flash .
connect a shutter cable to the camera and use the v6 ii as a remote shutter release .
there are some other triggering systems that can fire various brands of flashes from a different brand of camera , but their big drawback is that the flashes have to be in full manual mode . the cactus v6 can be used in this way , but its unique feature is that users can program in the flash they are using and then remotely adjust the power output . flashguns have varying guide numbers and ranges , so more than 30 different flashes have been profiled and pre - installed on the cactus v6 . this includes popular flashguns , such as canon , nikon , pentax , sigma , metz , nissin , phottix , yongnuo and godox units . a full list can be found on cactus’s website .
place multiple flashes at various positions and at greater distances . in fact , flash sync an entire setup with a cactus radio flash trigger .
cactus is also committed to adding more profiles with firmware updates , which are installed via a micro usb port on the side . however , should the flash not be recognised , there’s a chance that the cactus v6 will learn its profile , provided that it has analogue ttl .
before purchasing this cactus transceiver i had no experience using off camera flash . i ' m a total newbie photographer but found this super straight forward to setup for my fuji x - t20 . first thing i did was update the software via a download from the cactus website . then i attached one vii to my camera and the other to my nissin i40 flash that was mounted to a softbox . no communication errors at all . didn ' t run into any issues .
the x - ttl firmware gives photographers an unprecedented flexibility . the need for matching flashes with the same camera system for on and off - camera ttl flash photography is over – ttl without boundaries .
* available now ! download the free firmware upgrade on the v6 ii and v6 iis to have wireless cross - brand ttl on fujifilm , sigma and sony cameras . ( click here ) .
- capture the same action simultaneously from multiple angles on remote cameras by shooting on the main camera .
the godox v860 is original and the world’s first lipo powered camera flash , which obviously enhances . .
the cactus wireless flash system is a mixed bag . i loved the functionality for my olympus system . however , the build quality is pretty cheap .
it is very easy : simply attach one pocketwizard plusx transceiver to your camera . attach another poc . .
the
channel / group
protocol can be either on the trigger side ( as with the above - mentioned triggers ) or the camera / flash side ( as with canon ' s groups , channels , and id codes in their infrared wireless and rf protocols ) . so , again , these can change depending on the triggers or brand of camera gear you ' re using . don ' t assume compatibility of groups and channels unless both the trigger / receiver model match and the hotshoe protocol of the camera / flash match .
connect your portable flash with one of our highly - compatible cactus shutter release cables , laser or wireless flash triggers . you will need a controller and a receiver ( or a transceiver that does both ! ) – the controller sends the signal to the off - camera flashes that the shutter is released , and the receiver registers the signal from the camera to fire flash .
citroën c3 wrc is the sporty cousin of new citroën c3 which marks the brand ' s great return on rallies around the world . if we can guess the unique morphology , the charismatic face , the look and the curves of citroën c3 , its engine is the most efficient ever built by citroën . its extraordinary performances are to be discovered live on the social networks of the brand following the hashtag # c3wrclive !
with technology moving on so quickly , and photographers themselves always exploring new areas and styles of working , it’s increasingly commonplace for them to change cameras or own a number of different types . while some photographers stick to the same brand , it’s not always possible to do so . for those who shoot with a variety of different brands , the cactus v6 offers an inexpensive way to build an off - camera flash kit for all your cameras . recently , a lot of photographers who use fujifilm compact system cameras have adopted this as their off - camera triggering system for that very reason .

i ' ve just made my cactus v6 review available . i hope people will find it useful . the v6 is the perfect on - camera trigger for the rf60 but can also remote control the power levels of many modern digital flashes as well as legacy ttl flashes .
both the v6 ii and iis now has an automatic led af - assist light that makes autofocusing in dark environments possible â€“ even in pitched - black ! besides the camera - mounted v6 ii / iis , off - camera units will also activate the af - assist light , which helps focusing even when camera is far from the subject .
most flash - triggering systems need a transmitter attached to the camera and a receiver attached to each flash that users wish to fire . the cactus v6 works slightly differently , because it is what is known as a transceiver , meaning it can do the job of both the receiver and the transmitter . in order to use flash off - camera , you will need one cactus v6 mounted on the camera and one on each flash . a button on the side of the unit can be switched to use it either as a receiver or a transmitter . cactus also makes a flashgun called the rf60 , which has the same transceiver technology built into the unit . it boasts a decent specification sheet and a street price of around £120 , so if you’re buying into new kit , it’s worth taking a look at that option first .
lighting , aperture , shutter speed , the elements , photography equipment— there are plenty of factors to consider and skills to master when it comes to floral and nature photography . we deeply respect and admire these world - renowned floral photographers for their uplifting , inspirational , and thought - provoking work .
pocketwizard , radiopopper , and phottix all make triggers that interoperate with each other within the brand . you can mix both ttl and manual - only triggers , and they will all sync together , sometimes with group control .
the re - engineered and re - designed cactus wireless flash transceiver v5 ( cactus v5 ) , like its predecessors , remain powerful and reliable , and is ideal for photography of any kind . it sports a new transceiver design and powered by 2 aaa 1 . 5v batteries ( sold separately ) , each cactus v5 unit can serve as either a wireless flash transmitter or wireless flash receiver . different transmitter / receiver combinations are now possible , giving photographers unparalleled flexibility and control over their strobist setups .
other improvements in cactus v5 include support for any maximum sync speed supported by camera up to 1 / 1000s , working frequency of 2 . 4ghz , effective range up to 100 meters , implementation of a low battery indicator and 16 - channel rotary dial for channel selection , and dual hot shoe design to allow concurrent firing of an on - camera flash . together with the provided pc sync and 3 . 5mm cables and 6 . 25mm plug adapter , photographers may use cactus v5 with any * * portable flash and studio strobe with trigger voltage up to 300v .
both the v6 ii and iis now has an automatic led af - assist light that makes autofocusing in dark environments possible – even in pitched - black ! besides the camera - mounted v6 ii / iis , off - camera units will also activate the af - assist light , which helps to focus even when the camera is far from the subject .

mrfizzbin : yes , power output control is possible and sometimes requires manual profiling of the flash . but the supported flash systems are canon , nikon , and pentax ( flashes can be from any brand as long as they have one of the aforementioned system dedications ) . the v6 ' s hot - shoe is pretty brand - agnostic but does not include minolta . as i wrote , a bit of diy may work wonders , but it would be best to contact cactus about it . p . s . : it is a v5 with group control added , if you don ' t have one of the many compatible strobes .

cactus v6 iis hss wireless flash transceivers for sony mi shoe ( $ 95 at b & h photo ) join the quickly growing list of wireless flash triggers supporting high - speed synchronization on sony cameras . i have not had a chance to try this one out – but it looks interesting . please note that while cactus’ press release mentions focus assist – external focus assist lights are normally not compatible with mirrorless cameras , so don’t hold your breath on that one . please note : this is a transceiver which means you need one unit for the camera and one additional transceiver for each flash you wish to fire .

the combination of the nissin commander air 1 and the receiver air r will give sony owners with a new dimension of flexibility allowing them to wirelesslycontrol almost any kind of nissin camera flash andoriginal manufacturer ' s flash with nas and ttl & hss support . camera users who currently own a sony original flash will be able to make their existing
it ' s all proprietary , i ' m afraid , and interoperability is pretty much in - brand when it ' s there at all . ( though you may expect third - party makers to a least try compatibility with canon ' s rf system at some point . ) some pro - level equipment is compatible with the pocketwizard system , or at least versions of it , but that seems to be licensed . ( i ' m sure the good folks at pocketwizard have nothing against convenience , but they ' d probably just as soon you bought another of their units rather than simply copy their signalling system . oh , and you wouldn ' t be able to say you ' re
pocketwizard compatible
without violating their trademarks either . )
unlike shutter release cables , laser triggers allow more complex high - speed photography setups , ideal for freezing high - speed action like bursting water balloons or gravity - defying dance moves that are normally invisible to the human eye . even though they require a direct line of sight , nifty infrared camera triggers like the cactus lv5 allow you to set trip - traps for fast - moving , shy creatures in the bushveld .
the cactus lv5 is a clever flash trigger hybrid that works with a wired connection , and remote or wireless flash units such as the cactus v5 , v6 , rf60 and rf60x making it the ideal investment for the prosumer . not only does it allow you to trigger flash from 100 m away , but other impressive features include high - speed sync ( hss ) up to 1 / 1000 sec ( subject to the camera’s sync speed limitation ) , and 16 radio channel frequencies that allow multiple photographers to work within the same environment without triggering each other’s flashes . weighing a mere 300 g , there is no reason not to take this trigger with on wildlife photography expeditions .

while it may have started life as a humble flash trigger , the sixth generation of the cactus offers something no other device does . it can fire a multitude of flash brands from almost any camera with a standard iso hotshoe or pc sync port , while being able to adjust the power output remotely . canon , nikon , fujifilm , olympus or panasonic cameras can be used to fire canon , nikon , olympus , panasonic or pentax - fit flashes .
don’t forget to soften your light with the cactus 60 cm foldable softbox that controls the quality of light with its reflective silver interior and two white diffuser cloths , and the angle of light with the tilting lock handle . its soft rubber clamp allows for easy fastening .
besides remote power control , remote zoom control is now available to all compatible ttl flashes , which was only available on cactus rf60 series wireless flash before . this will give photographers much quicker controls by swapping controls of power and zoom settings directly on the v6 ii .

it is a very cool much more to come . however cactus surprised me by saying you can share the majority of the features . note there are going to be more however i believe what we have so far gives a good over view of the product at its current state .
the functionality the v6 boasts could easily cost four times that price . of course , the downside of anything built to be inexpensive is that the construction quality doesn’t compare to many of the more expensive options . however , the device’s plastic case appears to be robust enough . in summary , the cactus v6 is one of the best - value flash triggering systems currently available , and offers a wealth of features to satisfy everyone from the beginner to the enthusiast off - camera flash photographer .
great product . no misfires . love that i can change all receivers ( light power ) from camera transmitter . just make sure you update firmware before using or you may have sync issues like me .

petepixxx : i wonder if cactus is able to test with one once they go on sale since they will be a distributor of the godox v860 through gadget infinity from my understanding . considering you already have nikon flashes you can mix together with them and the v6 . as long as it uses the same protocol and pins as canon , nikon , and pentax it should work . again should , although it would be nice to get on the official list some how . i will ask if they have access to both of those . thats the idea behind the v6 is to consolidate all your existing equipment into one remote power controlled system . : ) i really liked being able to bring my nikon sb24 out of retirement . its a relatively powerful flash . i already tested it with my friends sb800 and sb900 .

the dedicated sony version – v6 iis , embodies all the desirable functions of its sibling v6 ii but with a sony compatible hot shoe on the transceiver body , ensuring a seamless and secured connection with sony cameras and flashes . mounting the v6 iis on a sony alpha camera allows the photographer to shoot above camera’s maximum x - sync speed and control power and zoom of sony , including those with a minolta / sony hot shoe via an adapter , and other v6 ii compatible flashes . it is the perfect wireless flash trigger for existing and new users of sony alpha cameras , especially those who may still have non - sony system flashes in their camera bags .
frequency self - tune ( fst ) , a new and groundbreaking feature , enables cactus v5 to automatically tune itself to its last working frequency when exposed to extreme weather conditions such as a sudden and large temperature change . not seen in any other solution on the market , fst effectively minimizes

v6 supports ttl pass - through on canon , fuji - film , nikon , olympus , panasonic and pentax systems . when using ttl pass through , make sure that camera and flash unit belong to the same ttl system .
the reversing camera displays the view behind on the cars touchscreen when the reverse gear is engaged . this view is enhanced with colour guidelines which show the proximity to any obstacle . a real expanded view to make reversing manoeuvres easier !
does the pixel adapter do ttl passthrough to a standard shoe size ? not sure the minolta pin structure would be able to be implemented via the mss shoe . note that is if you want to use a flash on camera as passthrough ttl . of camera power adjust is manual through the v6 transceiver on camera . currently , canon , nikon , and pentax flashes are support for remote power adjustments on comparable modes . the shoe is universal hot shoe standard shared size . and the older sony flashes would not even fit . only way i could see it working was if the adapter pasted through ttl , and the mss was configured for the sony , and they could crack the ttl handshake .
though it may seem pricey at $ 624 , the turbo 3 will reduce your shoe - mount flash’s recycle time to around a second and can make it last for upwards of 1 , 000 shots . it can charge up to two flashes at once and has a gauge to let you know how much power you have left . you can also use it to power a wide variety of camera bodies , and it can power your camera and a flash at the same time .
once you start dabbling in flash photography , you realise that the single most important accessory to your camera has to be your flash . it has the ability to transform dull , flat images into warm , flattering images that complement the subject .
wireless flash control for multiple off - camera flash units can get pricey quickly , since most manufacturer’s systems won’t work together . the $ 140 cactus rf60 has a built in 16 - channel transceiver with a maximum range of 328 feet , thanks to its 2 . 4ghz rf transmission , and a guide number of 183 feet at iso 100 when zoomed to 105mm . best of all , it can control multiple brands of flash units simultaneously in up to four groups . if you don’t want to use the flash as a controller , you can add the v6 transceiver for $ 55 .
cactus v6 triggers all other flash models via hot shoe , and studio strobes with pc sync male port , 3 . 5mm or 6 . 35mm port via optional cables ( see section 20 ) . this includes high trigger voltage portable flash models , and all strobe models with trigger voltage 300v or under . power remote control is not supported .
the fuji x - t1 was a major offering from fujifilm in 2014 with their first enthusiast - grade , dslr - styled camera . it packed a lot of firepower and terrific image quality but lacked in a few key areas compared to its dslr rivals of the day . with the improved x - t2 , the fujifilm engineering team has really stepped up their game and added some serious upgrades both internally and externally , bringing the camera line up from the enthusiast realm and into serious professional territory .

the first wave of firmware releases will be for fujifilm , sony and sigma . other camera systems , i . e . pentax , canon , nikon , olympus and panasonic , will follow one by one as we complete system integration on the v6 ii .
designed for use exclusively with sony cameras , the cactus v6 iis wireless flash transceiver is capable of controlling canon , fujifilm , nikon , olympus , panasonic and pentax system flashes all at the same time . it can support high - speed synchronisation ( hss ) at shutter speeds of up to 1 / 8000s , and also features a power sync mode that boosts flash contribution
the tricky thing about mixing different flashes is that most will have different power levels . for this reason , there is an option called absolute power control . this benchmarks the guide number of each flash and matches the light intensity . the flashes can then be adjusted in ev numbers . this means that no matter what brand of flash is being used , the power will be adjusted equally . some models of flash can be adjusted in 0 . 1ev increments , even if this isn’t offered on the flashgun itself .
