Question: I own a black magic 2.5k  camera and a Sony Ex3 will it hold either of them?
Document: I wanted a portable jib that telescoped without spending $900 for the aviator, that would hold up my work with DSLRs. This is for light-light dslrs only. I put a t3i on it, and the counter weights that came with it still were not enough to balance it out. I prefer to have a bit more weight than the camera so that it "assists" and makes a smoother up shot. It is a bit fidgety.
I used a Sony FS700 with this. It's a little bit heavier than a DSLR. It's not 5KG though, even with a lens. The counterweights weren't heavy enough so I had to add my own.I've used it twice and in that time I've discovered that the connector to the base of a camera was designed by an evil person. It's impossible to connect this to a camera with any real confidence as you can't actually reach the screw in mechanism.
While I've about maxed it out with a Sony FS700 on there and small lenses I'd say it would work better with a DSLR. The screw that tightens the camera plate is hard to reach and the whole thing can get a little sketchy unless you crank it down. That said, it's still a good buy.
It won't hold 11 pounds as listed ( I would be nervous ) but because of that this jib is very lightweight and packs down very small.Check out my full video review with setup and example shots from this jib on youtube!

)I put on a 5d Mk III with a 35mm 2.8L lens, extended the jib out all the way and extended the counter weight all the way, and it bent the rig's top bar significantly at the fulcrum (pivot point)and that was just with the 3 weights provided. I'm a bit discouraged by this.
Very adaptable to different lengths (up to 4 feet) and comes with its own weights (3 sleek black ones), which is nice; I don't have to be shopping around for ugly gym weights! The rod they screw on is also adjustable so you got some room to play, come balancing time and you can lock them with each other so they won't be falling off at all. It comes with a ball head adapter, if you have one; I won't use it.
...why it's as cheap as it is.It's rather flimsy in every respect. Oh, and the design makes it biblically hard to mount your camera with the thread. That being said, I have used it on a few jobs and it's done what it's advertised to do.
I haven't found this to be a problem since I am very tall and the camera is counter-weighted enough to still get smooth, effortless movement across the whole range of motion, but it's something to be aware of.There are really only three gripes I have with this jib.
It arrived with parts falling out. You can't get your finger under the knob to secure your camera to it. Calling that FRUSTRATING is an understatement, and I have small hands! You will need to buy an additional ball head if you don't want to be stressed out so much but then once attached it won't fit in the carry bag anymore.
The space underneath the screw is so tight that my fingers had almost no room to twist the knob. I "screwed" the camera for a couple of threads and THEN, tighten it from underneath. No biggie, though. Just a bit of practice.I absolutely recommend this item and the seller. Great product, great service, happy customer here.Happy shooting!
Answer: It should hold them, but it will not be steady. I used mine for about 2 months before it started to give out because of too much weight. I've used the 2.5K BMCC and know how heavy it is. I was using Canon DSLR's, namely a 5D MkIII with L prime glass on it, and the weights provided, and it started to bend the tubes at the fulcrum. It was great while it lasted, but I ran into problems with not being able to clamp the locks down tight enough to keep it from slipping out of place. Also, in any wind, it wasn't very sturdy, even with everything tightened down. The design is good in that it compacts down nicely, but overall I'd recommend getting one that is a bit heavier duty, like a carbon fiber one. Long story short, yes, it will hold them. Will it balance? Probably not. Unless you are shooting with a Micro 4/3, or lightweight DSLR like a Rebel Series or D3100, this ePhotoInc Portable DSLR Mini jib just doesnt' cut it.
