عدسة عين قياسية ER-H من Canon لكاميرا EOS R3

Been using this with my glasses and the silicone rubber is soft enough that it doesn't smudge the lenses. Much more comfortable than the hard plastic eyecups I've tried before.

The cushioning around the eyepiece is nice and even, really comfortable against my glasses without any pressure points. It snaps right into place on the R3 too, no fuss at all. Exactly what I needed.

The silicone rubber is much softer than the hard plastic eyecups I've used before, and it actually stays put against my glasses. My eye feels cushioned even during long shooting sessions, which makes a big difference when I'm tracking fast-moving subjects.
