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,it can fit sigma contemporary 150 600mm.the compartment inside the backpack is removable, you can DIY according to the size needed. 

The adapter is designed for Nikon lenses, including D mount. If the Tamron fits the Nikon D80 it should work. As for the lack of aperture ring on the Tamron ... not sure about that. Perhaps the Nikon D80 has an in camera aperture selection. 

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.
