I bought this after reviewing DSLR Video Shooter on YouTube. It's big enough for my Nikon D600 but can also be used with my Sony a6000. Lots of bells and whistles and gadgets, but NO instructions. I think someone should already know how to assemble it before buying it? But the grip is a big plus and if I place it on the left I can hold the camera on either side and the results are much better. The top handle can be mounted on the front or back of the cage, allowing me to attach either a Rode Video Pro video mic or a small monitor to it. Plan to play around with this to find the best configuration for you.
