hi,this Pro Kit filter can not used on 95mm size lens,because we do not have 95mm adapter ring. 

as long as it has a 1/4 screw mount,the tripod could work with the Nikon z6. 

Make sure you get the kit that is compatible with the canon. The step-up rings are threaded to fit the lenses filter size and the light fits on the ring adapter. 

hello , we are the seller, you could use an adapter to step the 52 down to a 49 , there is a adater ring kit https://www.amazon.com/dp/B00JL4HGAI, 

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.
