I put a blog together about the SX10/SX1 where I compare them with the S2IS since this is my Canon still in use.
When I read about the SX1 viewfinder resolution yesterday something bogled my mind.
Normal resolution with the SX1 or SX10 3.648 x 2.736 = 10 mp.
Wide resolution with the SX1 3.640 x 2.160 = 7.8 mp so just a crop of the 10mp
Now if you shoot normal 10mp with the SX1 widescreen, the picture will be resized for the screen and you have a black bar on either side that leaves 110k effective viewing pixel for the viewfinder and 172k pixel for the display if I did my calculation right.
SX10 screen 2.5" 230k ca 552x416 - 4:3 10mp
viewfinder 0.44" 235k ca. ca. 560x420 - 4:3 10mp
SX1 screen 2.8" 230k ca. 639x360 - 16:9 7.8mp
(172k ca. 478x360 in 4x3 10mp)
viewfinder 0.40" 148k ca. 513x289 -16:9 7.9mp
(110k ca. 383x289 in 4x3 10mp)
So manual focus will be almost impossible with the viewfinder and not so good with the display.
If this is right then the viewfinder from the SX1 in 10mp is even worse than the one in the Canon S2 (115k) and will be a deal breaker for me.
Somebody please proof me wrong
