I bought with the eye cup for my D750 and am very happy. Sits not 100% fixed bombs, but it works. But what is still needed on the D750, which you can fix it is:
Nikon FM / FE2 and eyepiece Nikon DK-22
With all three parts you can just plug in or replace the eyecup.
I am satisfied, but because the mussel could sit a little harder and so threatens a loss, I give only 4 stars. I mean but not lost.
