Question: Is this Flash Wireless or do I need to purchase another purchase another product to make off shoe, I also have canon 580exII please advise
Document: The product descriptions says for Canon but I received the Nikon version instead.The flash works but not ETTL on my Canon DSLR. Doesn't sync as a slave flash either.
I have used this as an off-camera for sometime and its truly excellent. It works great when paired with the YN622 receivers and my canon 60d. I can control zoom and expose right from my camera menu. Its a great entry model into wireless flash.
Love this one , i got this mainly because i also purchase YN622 and they work together just fine ..
everything about this thing feels better than my canon one does, and for a fraction of the price. the screw on hot shoe connector is a lot better than that canon lever-system. the canon one attaches and detaches easier, but it has also fallen off my 5diii a number of times. the screw on one takes a seconder long to switch, but i know that sucker ain't goin' nowhere.the master/slave feature works perfect with my 430EXII, but i don't really use it. if i'm using multiple lights, they are all off-camera, in which case i pop on my YN-622C's.
i'll start off by saying that i'm a wedding photographer mainly. i LOVE using flash. if i'm using studio lights, then all these features are meaningless to me, however, out in the field when you don't have time to use light meters and take a billion test shots you need these features. the ETTL on this thing has been flawless, and the HSS is waaaay more powerful than i thought it would be.i have a canon 430EXII along with other flashes, but i don't even use my (overpriced) canon flash unless i'm using multiple strobes.
The Flash was well packaged for safe shipping, it arrived on time and works great. I can't say I have any problems with the entire transaction as they lived up to my expectations. I am still using the Flash and so far it is a great purchase no regrets at all.
I pulled my flash out and mounted it to the camera after having it sit in a closet for one month. To my dismay they battery door popped open. The only thing I can think of that might have prevented this was not to leave the batteries in the flash. However I also don't want to be opening the door all the time for fear of wearing out the tabs that way either. In either case this is a great flash, but has a critical flaw and I would avoid it for that reason.
I am thinking of selling my 580exII and getting more of these. I just ordered my third one. So far these flashes rock.
My photo friend had been shooting with Yongnuo flashes for sometime and recommended I add a flash to my wish list for a future purchase. After a recent photo shoot along the Amgen bicycle race, I noticed the riders faces were dark and difficult to see the stressed features so I took the plunge and bought a Yongnuo for myself. Within days of the flash arriving, I found myself at an outdoor, evening 40th birthday party where the flash was required. I had no training, no practice and the pictures captured on the 50mm were stunning.
the power is great. if you need an ETTL flash this is a no-effin'-brainer.
Answer: Yes it is. You can use it as a slave and trigger it with your master
