JJC EN-DK19 Large Eye cup for Nikon D500 D800 D800E D810 D850 D3 D4 D4S D5 Df, Ergonomic Design Oval Soft TPU Rubber Eye Piece, D850 eyecup, D800 EyeCup, D810 EyeCup, D5 EyeCup, as Nikon DK 19 Eyecup

Well made product. Very comfortable and blocks the sunlight so I can see the viewfinder screen.

I use this Eye Cup on the Nikon D810. It fits well and works wonderfully. To me, it is so much better than what the camera came with. You can adjust it to block any side-light from obstructing your view and is much more comfortable as well. Definitely worth the small price.

I have one for A Canon 5DSR and it fits perfectly. I both not for the D850 and it needs to be larger to be usable. I would not buy this again.

Great way to reduce stray light when trying to focus or compose image in camera Nikon D800 and D810. Easy to install and once in place the cup can be rotated depending on vertical or horizontal holding of camera.

The lens is not clear blurry. I had to remove the one that was shipped with it and use it on the one i had.
