Viewfinder EVF (0.40" type), aspect ratio 16:9, approx. 148,000 dots
Just got my hand on the SX1 manual and it seems I am right
If you shoot 10mp with the SX1 you have a 2.17" screen (something between the 2" from the S3IS and the 2.5" from the S5IS) with a 172.000 pixel resolution and your viewfinder will have a 0.31" with 110.000 pixel resolution and that is worse than the Canon S1IS from 2004 with EVF (0.33" type), approx. 114.000 pixelsDon´t believe me? Here is a 1:1 pixel count chart I made to believe it myself.
Since the viewfinder of the S2IS is even a bit better than the one from the SX1 in 10mp mode I made a side by side comparison so you will get an idea. Please concentrate only on the sharp parts of the image the unsharp is distortion of the picture taking camera not the actual clarity of the viewfinder.
Ok, so why am I so obsessed with the low resolution viewfinder you might ask.
When I brought my brand spanking new Canon S2 I wanted a camera with manual focus but with that low resolution viewfinder and the low resolution display what was too small (1.8") also I was not able to use successful the manual focus. It did frustrate me so much that most of the time I did not use the S2. Now 3 and a half year later I will not make the same mistake.
