Sony FDA-EP18 Eyepiece Cup

I was worried the rubber would feel flimsy, but it’s actually sturdy and grips the viewfinder snugly. Makes composing shots much more comfortable without stray light sneaking in.

This little cup slides right into place and stays put, no wobble at all. The fit is perfect on my camera's viewfinder, making long shooting sessions much more comfortable.

My old cup cracked after years of heavy use, and this replacement slides right into place with zero wiggle—the fit is exactly like the original. Feels solid when I press my eye against the viewfinder, and it doesn't pop off when I'm shooting all day.
