Promaster Nikon DK28 Eyecup

Fits my Nikon perfectly and stays in place even when I’m out shooting all day—the rubber is just soft enough to feel secure without being flimsy.

Finally, a replacement that actually stays put on the camera — the rubber lip grips perfectly, unlike the loose-fitting ones I’ve tried before. It feels just like the original, and installation took about two seconds.

Lost mine on a hike and this replacement feels just as sturdy as the original, with that satisfying click when it seats into the viewfinder. The rubber is tacky enough that it stays put against glasses all day. Glad I didn't have to buy a whole new camera over a tiny piece.
