Thomas H. ★★★★★ Oct 21, 2026

Fits my EOS R3 perfectly and blocks out light much better than the standard one. The rubber is pliable enough to not feel stiff against my glasses, which I appreciate during long shoots.

Isabella W. ★★★★★ Oct 20, 2026

Finally, an eyecup that actually stays put when I’m shooting fast action—it locks onto the R3’s viewfinder securely without any wobble. The soft rubber rim makes long sessions way more comfortable against my eye.

I've been using this eyecup on my R3 for a few weeks now and it stays firmly in place even when I'm shooting in portrait orientation. The shape contours nicely around the viewfinder, which keeps stray light out during bright outdoor shoots.
