Well, to my Oly he sees in black truly like a foreign body, since I have the white model. But I also have the E-PL5, because the viewfinder looks very harmonious.
The gain in comfort for me is almost priceless: the viewfinder is bright, clear and not really pixelated, the image is large. The sensor for automatic switching works flawlessly. It is as if I have new cameras.
If I do not need the viewfinder, which makes the camera (s), of course, much more massive, I take it off easily and put it in the storage bag, and then in his jacket pocket.
A real investment that has paid off but for me the very first day, I have but now raised my cameras to a new level.
What I like: the ability to fold the viewfinder upward. Herrlich. I use quite often.
