I have a 50mm prime, 24-70, 70-200 and a 35mm prime and it fits them all. If day as long ss your lens has internal filter threads and is one of the sizes listed you will be good to go. 

Yes, it will fit any Sony e mount body, either full frame (a7..., a9...), or aps-c (like a6500, etc) 

I don’t think so. I night this to use on my Nikon D3100 with a Tamron 70-300. Neither are very heavy but this head would not keep my camera still. It crept down no matter how tight I made it. I think your camera and lens are heavier so I would go with a better name brand. 

FD-EOS fit for Canon FD mount lens and canon EF mount camera body. canon 60d is EF mount, so the adapter ring can work with your camera, but you need to check your lens mount. could you pls let us know your lens specific model? service(AT)kentfaith(DO NOT)com, Please note: It is not same between Canon FD mount and EF mount, this adapter ring is only for Canon FD mount lens, please contact us if you want to purchase for Canon EF mount lens. 

Yes, I use it with my Canon 6D and Tamron 24-70mm. It's an amazing tripod.
