[0.1 lb] I use this adapter with my B4 ENG lenses on the Blackmagic Pocket Cinema Camera with pretty great results, especially when stopped down to f5.6 for that sharp image.It's well built and very easy to use. The only downside about it is that it is mainly only for the BMPCC and Fotodiox really do need to produce a similar product for the Panasonic GH4. Olympus OM-D and also maybe the new Samsung NX1.Here is some test footage I supplied to -------

[0.1 lb] Love the portability and image quality. A downside is having to connect to a monitor anytime you’d like to make any changes, but once you rig it up and get a small 5” monitor you are good. I do not regret my purchase.

[0.1 lb] Purchased as a “set it and forget it” webcam.  I wanted very high quality, yet portability. I agree with other reviews the button navigation is a bit challenging but that is due it small size. It was smaller than expected and discreetly lives on my desk. If you see my photo here it, it is not distracting from 4' away behind my monitor..  If I ever use it for event recording, I won’t mind bringing my small FeelWorld monitor.  I spent an hour comparing models and am happy with this as a sole webcam plugged into a Blackmagic capture device.  Should I relocate this to the ceiling the SDI output will come in handy. I was more confident in this camera's image than less expensive models by others with PTZ abilities, so I am very happy with this choice.

[6 x 4 x 0.01"] Convenient and compact camera, convenient to place in hard-to-reach places. Of the studio functions, the camera supports RCP and Tali. Works great with Ursa Broadcast G2 cameras, the image is almost the same

[0.1 lb] I bought this camera for a specific purpose outside its core function - not for a secondary studio camera but as a lightweight solution to a gimbal rig. I wanted a 4K cinema camera (though it is limited to UHD only) that would work well on a DJI Ronin gimbal. The rest of the Blackmagic camera line, even the pocket models, were too heavy for these prosumer level of gimbals, especially once outfitted with a cinema-weight lens. The Micro Studio Camera, fitted with a stills lens and connected to a SmallHD monitor and a T7 SSD via its USB port, is a well balanced and practical solution. A few caveats: the lens needs to have manual shutter/f-stop control as the camera can only otherwise be controlled via an ATEM console (ditto for ISO and focusing); rack focus is not practical except perhaps via a wireless focus puller added to the rig (but even then monitoring is problematic); the crop factor is severe, so something like a Metabones focal reducer would be useful. But it works well for what I wanted to have and I now have a separate, complete rig for gimbal work I don't have to build and break down constantly.

[6 x 4 x 0.01"] It does what it's supposed to do.

[0.1 lb] The product is well made with subdued colors.
It fits perfectly with the OLIMPUS E-M1 mark III that I own, and the B4 lens can be firmly attached.
There is no metal rubbing, rattling, or distortion described in the reviews of low-end lens mount adapters.
You will have no regrets if you buy this product.

[6 x 4 x 0.01"] No problems using this adapter on my BMPCC MFT camera. Works great with all of my manual rokinon cine lenses. Plus the adapters manual iris will allow you to use EF automatic lenses.

[0.1 lb] Great price/value, great size, great connectivity.

[6 x 4 x 0.01"] Not just a studio camera, but a great compact camera for a handheld rig. I have it rigged with the XLCS Designs cage and am very pleased with the quality of the footage I am getting, even in low light with the dual gain/iso. Flies great on a gimbal also. Only downside to the camera is the placement of the function buttons. I think I have found the perfect budget cine camera which will cover all my needs,
