January 22 2008


I’ve posted the camera name that belongs to each picture below, but I threw you a curve.  On the soft 75-300mm lens-bottom row, I used the Konica Minolta 5D 6.1mp camera to compare to the A700.  It doesn’t seem to make any resolution difference with the addition of twice the megapixels, but that’s no surprise.  On the top row, it appears the A100 is sharper, but it’s really just the in-camera processing that’s adding extra sharpening over the more reserved A700. If I sharpened the A700, it would be the same as the A100.  For the top row test I used the Sony 50mm F/1.4 lens at F/8, which is much sharper than the full telephoto (at F/5.6) shot with the 75-300mm.  As you can guess, it really makes no difference simply adding 20% more megapixels with a sharp lens, or 50% more with a soft lens. This topic might make a good page length article…coming soon.
