عدسة عينية هيدروفوبيا EP-R3 من ثينك تانك فوتو لكاميرا كانون R3

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.
