1.) after a few days is canceled the right tab with me. Solution: I have that thing glued to the camera with a simple contact adhesive. With what we know today, I would give a small rubber strip between the tab and the context of the eye cup, which should resolve the issue.
2.) For vertical shooting can be difficult to turn the rubber shell. Solution: half a drop of sewing machine oil and even misses that.
3.) display for viewing the image made is covered by the shell. Solution: Pull rubber shell.
Advantages: much more convenient. No more prints on display (!!!). No flare or significantly reduced.
I'm not wearing glasses.
Limited buy recommendation. Nevertheless, 4 points, because the price is fair. I do not want to miss the eye cup.
