Strange: 10 Mpix with a 2 by 3 ratio makes 2582 x 3872 pixels (more or less a few...). 1.3 conversion (compared to 24x36mm "full frame") gives 18x27mm sensor size. If my math is correct, 18mm / 2582 = 7 micron, NOT 9... The 5D is approx 2920 x 4380 in 35.8 x 23.9 mm, which makes about 8,2 micron sensor pitch. Unless my math is bogus somewhere, which is more than probable at this time in the week... Patrice
