Soft Silicon Camera Viewfinder Eyecup Eyepiece Eyeshade for Canon EOS 6D2 6D 5D2 5D 90D 80D 77D 70D 60D 50D Rebel T7i T7 T6s T6i T6 T5i T5 T4i T3i T3 T2i T1i SL3 SL2 SL1 Replaces Canon EB Ef Eye Cup

Fitted well on D750 Nikon.Excellent product except country of orign not mentioned while odering. Though imported from USA but made in China. I desist on buying products made in China.

Blocks out extraneous light and doesn't hurt your eye. Not quite as solid as the OM one but the functionality is far greater

It was perfect for my a6000. More secure than the original and very comfortable.

LOVE this eye cup! It helps me use the eye view better especially on a sunny day. Great quality and easy to install.

semble tres bon et c est installé tres bien

So in theory, this product is great. I see the appeal of it and love how it can block out all other light when looking through your viewfinder. The product works great for that purpose. I, however and unfortunately, wear glasses and the product is designed to fit into your eye socket, not over glasses. Take that into consideration if you wear glasses.
