That\'s true, and it\'s good to try to sort out the different issues that come up and not get them all mixed up as one big issue.

I\'ve rubbed elbows with guys shooting pro mx, which is a moderate challenge to af servo systems, since DLSR\'s became available. In that time, every 1D model since the first has had individual copies returned for QC issues. Some guys have never had issues.

Clearly the MkIII had some system wide hardware issues, at least early on, or Canon wouldn\'t have fixed the mirror box. That\'s a different issue from single copy QC.

And clearly there are going to be people who either don\'t use or set up their camera\'s as well as others. That\'s a different issue from design or QC.

I do think the set up variables became expontentially more complicated with the MkIII, and with that the opportunity to do mischief by setting it up wrong for a given situation. The IV has gone even further in this regard (e.g., selecting a single docus point with all 45 activated for tracking assist).

The guidance Les offered here in a couple threads a few days ago is a great place to start. Keep it simple, be patient, and tweak one at a time.

As far as whether RG is biased to Nikon or against Canon, I can\'t really be bothered with that because there\'s no way for me to know and I don\'t have the energy to chase that rabbit. That said, I don\'t think it\'s uncommon for people to have a different sort of unconscious bias ~ me, you, RG: the bias toward validating our own experiences and judgments. Makes it difficult to make sense of things sometimes when there are a lot of voices.
