Don't forget the Hyper Manual mode. http://www.ok1000pentax.com/2009/04/pentax-hyper-program-and-hyper-manual.html http://forums.dpreview.com/forums/read.asp?forum=1036&message=36220193
Shooting with m42 lenses is best on a Pentax, because of Hyper Manual. Also, you should try to use an old preset lens on your Pentax (like the inexpensive Tele-Takumar 200mm f5.6). Presets work great and aren't hard to get used to at all on a DSLR.
