A:AnswerYes! I am able to use the Weebil with my BMPCC4K and a Canon 24mm lens with no cage but I also have to use a small rig counter weight to balance it. After that, it works perfectly!!!
A:AnswerYes. Works great with both my 70D and 90D. You have to remember to open the lcd if you use your camera that way, remove kens cap and if you are using a zoom, do the initial balance with the focal length in the middle of your lens.
A:AnswerYes, you need to buy one separately but Zhiyun provides a follow focus ring and it's very convenient to use..check it out before you buy it though.
