Extended Round Z6III Z5II Z7II Z6II DK-29 Eyecup, Upgraded Soft Silicon Eye Cup Viewfinder Eyepiece Eyeshade Cover for Nikon Z6 III Z5 II Z7 II Z6 II Z7 Z6 Z5 Camera, Replace Nikon DK-29 Rubber Eyecup

Good fit, very comfortable. I wear glasses and after a bit of time it would become uncomfortable to shoot. This gives me distance between my camera viewfinder and my eye so it fits comfortably. I also noticed less glare in my viewfinder. Not too expensive.

Perfect addition for the z8 user. Blocks external light and has a very comfortable feel.

I bought a scrap-heap Nikon D200 that had a host of problems, one of which was a missing eyecup. What little OEM supply remains is priced too high, and this one honestly just looked better to me. Before, with the missing piece, I was having to jam my face right up against the back of the camera; now I can keep a little more distance, since this eyecup does a great job of blocking out ambient light. It also seems to stay in place pretty firmly - the fit doesn't seem loose at all, at least not in the early going. If you have an old DSLR, you could do a lot worse than this one.

the eye cup is nice and pliable and blocks external light very well. installation is incredibly easy. only downside i've found so far is that on a nikon d5600 the screen is blocked from folding out while this is installed fully. it's not hard to partially take the shroud off to fold the screen out if needed, but it is a bit annoying.

Exactly what I needed. Thank you!! Recommend.

Wearing oakley rx with aggressive curvature, this one seals better than the stock eye piece. I'm sure it could be cheaper elsewhere Fits like OEM. Press the button next to the cup, old piece comes off, new one slips on.

Cup is nice and adds comfort. Unfortunately it came bent out of the box and after 2 weeks the shape still is not round. Returning from Europe to USA is too cumbersome, so I'll have to keep it...

Slid right on to the D3300 eyepiece and makes the data in the bottom of the view finder much easier to see
