If you look at for instance a G10/11/12... they use exactly the same imaging/computing core, which also manages the contrast AF from the imaging sensor (Digic). So it is not that... Canon has contrast detect AF from the imaging sensor + Digic computer covered well.

Yes, I realize that. I just wonder in how far the APS-C, APS-H, and FF sensors and circuitry are really prepared for this. There are a few Canon "compacts" which use USM, so therefore it should really be possible <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='

Kind regards, Wim
