But Canon seems to have some big problems in this regard. My EOS digital rebel can't focus any of my lenses properly. The 1Ds I just got can't either. The thing I've noticed that bugs meore than everything else, is that the same camera and lens on a tripod pointed at the same target will give different readings if you actuate the AF via the shutter release several times. Initially I thought it was a settling down sort of problem and after tapping the release a few times the lens had homed in. ----------------------------- Javier,
There is more to it that this and if you are having issues with both bodies and lenses something is really wrong. There were issues with early 24-70mm lenses, this caused backfocusing due to reflections off the sensor. But this is also a problem what was found in Nikon's D70 and yes, even the D2X, and especially the D1H, which was very problematic with focusing. If you ever see a PJ using this camera you will see them take about 8 shots of each subject. Reason being the first 1-2 are always out then the camera acquires proper focus. I would send your cameras along with the lenses that are giving you an issue to Canon for calibration.
