After 20 years of OVF (Canon AE-1) I´ll never forget the day when in 2003 I first looked through the viewfinder of my first digital camera, a used Oly C-2100 UZ.
I thought OMG, how shall that work?!
But - it only took me a few days to get used to that EVF and pretty soon I really liked it! Can say during the next five! years I´ve got everything with it I wanted to get, but what I liked best, exposure was usually "spot on", thanks to the EVF´s WYSIWYG characteristic! Not the OVF way, everything looks nice in the viewfinder, you take the picture and then only in review you see that you better had dialed in EV-O.7 or better had used a different aperture or shutter speed.
Sure not the best advice for fast action shots, lol, but usually I had metering set to spot, looked at my subject through the viewfinder, moved the camera to different elements in the frame, often not even my main subject and watched how the brightness/darkness situation in the EVF changed. Once it looked good to me I pressed AEL, focused, recomposed and took my shot.
I really wouldn´t mind if my 520 had an EVF; I could do with the lousy year 2000 EVF technology of the UZI, so year 2010 technology should be "a piece of cake", as CC of Oly talk would have said!
