Yes, it really seem to be an entirely naming issue...

Also, do you think Autofocus Micro Adjust is at all useful? I've been reading completely different opinions on that. Some people say it should be on every SLR camera as most lenses will need calibration to properly work on a body, others say it is an emergency measure just in case you are unlucky to end up with a non-calibratet lens and don't have time to have it serviced.
