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

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. 

We installed it on our Canon RF 24-105 lens and it was possible to use the lens hood on this lens because the lens hood attaches to the lens via the bayonette mount which is on the outside of the lens diameter and the magnetic filter adapter screws into the thread on the inside of the lens. 

hello if your nikon camera is af mount, yes, you could make the sigma 70-200mm f/2.8 ex dg apo hsm large aperture macro zoom lens work with canon with this adoptor 

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.
