I bought the viewfinder, because taking pictures with display is a little difficult in strong sunlight. Besides, I'd rather be with an eye on the viewfinder when the camera having to keep one meter away from me. The electronic viewfinder is actually processed 1a, has all the necessary impressions of the information (can be set as on the screen as well) and a super resolution, the image is sharp adjustable by the small diopter slider. It is very well thought out, that the display is concerned, once you no longer covers the viewfinder with the eye - thus you can use the touch screen for settings immediately. However, it is the camera if you do not want this, set on manual switching. So completely satisfied? Not quite, unfortunately is a fatigue of the eye to versprüren extremely quickly, so you need a break after half an hour taking pictures, so as not to spoil the eye. I always try to work without flash, it does not bother me much that the insertion is confirmed by the viewfinder. But that is a minor drawback. All in all, a very expensive accessory, on that one, but no longer want to do without.
