Nikon DK-33 Rubber Eyecup

The rubber is slightly tacky, so it grips the viewfinder rim perfectly without slipping off during a shoot. It’s a simple fix that makes composing through the eyepiece much more comfortable.

The rubber is just pliable enough to create a good seal around my eye, blocking out stray light when I'm shooting in bright sun. It hasn't budged or popped off since I snapped it into place.

The rubber is just stiff enough to stay put against my eye while shooting all afternoon, yet it doesn’t press too hard around the viewfinder. Snaps on and off in one clean motion, exactly like the original.
