Subject: RE: How useful is SDM?
Is this something that should be ignored in making a choice? An
important factor? Somewhere between?
Fast auto-focus. How important that is depends on what you're doing with
your camera.
The sad fact is, this doesn't hold true with Pentax.
While SDM AF is nominally faster than screwdrive, it isn't a night the night
vs. day thing you will find if you pick up a higher end Canon.
Seriously, if really fast AF is someting you really need, Pentax is not the
camera maker for you.
