Meanwhile, I could test this eyepiece a few days and have to say: a good thing (not only) for eyeglass wearers! Although the viewfinder is slightly smaller, appear to be farther away, but I have a better overall view. Reminds me so a little on the "High-eyepoint viewfinder" the Nikon F3. Light Vignetierungen in the corners have me still disturbed after the first use, but they are only visible with highly uniform surfaces and influence the function in any way. For normal shooting which falls no longer on. The currently 16, - EUR 'not such a big sum' are well spent in my opinion. A positive side effect and therefore quite well for people without glasses a recommendation: you do not have quite as much to squeeze the display nose ;-))
