ProMaster EyeShade Sony FDAEP10

Finally, an eyecup that doesn't pop off every time I press my eye to the viewfinder. The rubber is soft but holds its shape perfectly against my glasses.

Replacing the old flimsy stock eyecup with this one made a huge difference—the rubberized grip is much more secure when I'm pressing my eye to the viewfinder. It's a simple swap that just fits perfectly, no wobble at all.

Finally, an eyecup that actually stays put on my Sony body. The fit is perfectly snug over the FDA-EP10 mount, and it blocks out side light much better than the stock piece ever did.
