I have heard of this and was wondering why some of my shots arent coming out as sharp as I thought they should. Look at the pic of the macaws below. My cameras focusing point was actually on the bird that was closest to the camera, right over his face. My other settings were as follows File Name IMG_1798.JPG Camera Model Name Canon EOS 10D Shooting Date/Time 3/29/2005 12:40:09 PM Shooting Mode Manual Tv( Shutter Speed ) 1/2500 Av( Aperture Value ) 4.0 Metering Mode Evaluative ISO Speed 800 ( Don't laugh about this one it was the first shot I took and didn't realize the ISO setting) Lens 70.0 - 200.0 mm Focal Length 109.0 mm Image Size 3072x2048 Image Quality Fine Flash Off White Balance Auto AF Mode One-Shot AF Parameters Contrast Normal Sharpness Normal Color saturation Normal Color tone Normal Color Space Adobe RGB File Size 2470KB File Number 117-1798 Custom Function C.Fn:01-0 C.Fn:02-0 C.Fn:03-0 C.Fn:04-0 C.Fn:05-0 C.Fn:06-1 C.Fn:07-0 C.Fn:08-5 C.Fn:09-0 C.Fn:10-0 C.Fn:11-0 C.Fn:12-0 C.Fn:13-0 C.Fn:14-0 C.Fn:15-0 C.Fn:16-0 C.Fn:17-0 Drive Mode Continuous shooting What am I doing wrong??????
