Nicholas B. ★★★★★ Oct 22, 2026

This eye cup snaps onto the Canon R3 and feels snug enough to block stray light when I'm shooting in bright sun. It’s made of a slightly firmer rubber than I expected, which actually helps it stay in place better than the stock part.

Finally, an eyepiece that stays put during fast shooting; the rubber seal grips the Canon R3's viewfinder really well. It's a small upgrade but makes a big difference when I'm out in wet weather.

The seal is tight enough that I don't worry about rain on the viewfinder anymore, and it attaches securely without any wobble. Definitely solved the fogging issue I had with the stock eyepiece on my R3.
