Dear Customer, so sorry to tell you that this adapter won't allow your nikon 1 s1 lenses to mount to my canon t2i. 

hello. the adapter can work with a nikon af-s dx nikkor 35mm f/1.8g to 6d mark 2 

For Canon DSLR+Marco Ring+E-TTL+GN14 can work with canon 6d mark ii 

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.
