A:Answer As of the latest firmware release the a5100 is not listed as compatible. Without trying one out myself it's hard to say how it would react, but I would assume that the ONLY functionality that would work for you would be the gimbal phone and hand controlled movement and the general stabilization. I say this because you have to calibrate the gimbal manually anyway to align the center of gravity, so as long as the camera is within the weight capacity of the motors with whatever lens you are using, there is no reason for it not to work. You'd have to use a different mechanism to trigger your shutter, auto focus, etc. remotely, or use servo mode and the like to automate some of it. You would also not be able to use the Raven Eye expansion if you wanted the image transmitted externally for remote operations. For that reason if you do get one, I'd get the stand-alone and not the pro kit, as that will have hardware you will pay for but not be able to use.
