Canon EF Eyecup

The rubber is firm but comfortable against my eye, and it fits snugly on my camera body without any wobble. After using it on a long shoot, I noticed it blocks out stray light much better than the old eye cup I had. Definitely worth the few bucks for the added comfort alone.

My glasses don't get smudged against the viewfinder anymore since this eyecup cushions everything so well, and it snapped right onto my EOS body without any fuss. The rubber is soft enough that it's comfortable for long shoots, but it stays put firmly.

Swapped out the old one on my DSLR and this fits perfectly—no wobble at all. The cushioning is firm but soft enough that my eye doesn't hurt during long shoots, and it stays put even when I'm adjusting the diopter.
