I wonder...Canon makes the AF slower with a teleconverter attached, perhaps because the longer focal length requires more critical focus. Perhaps Canon intentionally slows the AF slightly for greater accuracy due to the longer apparent focal length?


I dod notice when doing AFMAs that with some lenses (e.g. the 85L), when focusing from MFD to the target (but not the reverse), the 7D would overshoot slightly then come back to focus, whereas the 5DII just went straight there.
