Welcome to the club
1. I second i_trax on getting an LCD Loupe, whatever the brand
2. Don't know about other DSLRs (perhaps high-end models don't do that), but my K-30 clacks its mirror 4 times per shot when using LV (CLKose, CLKopen, *shutter*, CLKose, CLKopen)... with the K-01 you only have the shutter to worry about
3. I second AfterPentax Mark II on portability... slips just about everywhere, with the XS, a 18-55, a manual 28mm...
4. It's fantastic for macro and tripod work, with big, clear indications on the LCD and no unnecessary clutter. I find it very easy to read.
