Sony FDA-EP19 Eyepiece Cup

Finally a cup that actually stays on my a7 IV during long shoots—the fit is snug against my eye and blocks stray light way better than the worn-out original it replaced. Was a little pricey for a hunk of rubber, but it's genuine and clicks on perfectly without any wobble.

The rubber is firm enough to stay put but not so stiff that it digs into my eye socket during long shoots. It snapped right onto my a7 IV and blocks stray light exactly as it should, which is all I really needed.

After a few shoots with my a7 IV, I can finally frame without my nose smudging the LCD — the cup’s soft rubber sits high enough to block stray light, and it hasn’t budged once during a long handheld session. It’s a tiny part, but it makes the viewfinder feel like a proper sealed window.
