JJC Oval Shape Silicone 360º Rotatable Ergonomic Camera Viewfinder Eyecup Eyepiece for Sony Alpha A6400 A6500 A6600 - Upgrade from Sony FDA-EP17 Eye cup Review

Love the shape and size - the only problem is that it interferes with the use and functionality of the touchscreen - it's too big to just pull the screen out

Found on A6500, the tilt screen cannot be fully opened. Otherwise it seems to be working fine. The eyecup should either be softer or protrude slightly from the camera and leave a little more room.

Love this item! In glasses, it is soft enough not to be afraid of scratches (although, of course, in this case it does not block all the light). When used without glasses it really doesn't let in the most light! You can also rotate it to better fit your face. I think the only downside I can think of, while necessary by design, is that it's so big that it covers a decent chunk of the screen. This isn't an issue all that often, but it can be annoying when you're switching between the viewfinder…
