Just in case you were not aware, the a/f sensor is much larger then the red square in the viewfinder - it's roughly the size of the oval in the viewfinder.

That is something which i haven't actually really realized till today and i'm thinking that might have a lot to do with some of the more tricky autofocus tasks i was attempting. Thanks Screwdiver!

FocusTune

The current version of Focus Tune from Michael Tapes Design does NOT support any Pentax cameras yet. But they are working to resolve that soon. I was on their site today checking on that, since I am also interested in using that as soon as it is available.
