If you want really narrow depth of field, particularly with wide angle lenses, you might find micro four thirds limiting. You can always stop down a lens, but you can't open it up beyond a certain point. Obviously to say that you lose total control over depth of field is incorrect.

The subject will be far from exciting - an old Nissan Sentra :) - but hopefully the results will be useful to you. I'll post the pics tomorrow evening.

Pentax claim to have fixed this problem, and lenses manufactured in the last 18 months should be fine.
Also of note: since this thread was started, a firmware hack has been published which allows users to disable the SDM and convert their DA*16-50 or DA*50-135 to nice reliable noisy screw drive. I did this to my second DA*16-50 when its SDM failed, and it still goes like a two bob watch.

Hey chuck,
I'd say it matters what effect you want. I got some books from the library that helped me understand some of the basics of photography that using a P&S camera never taught me.
I can suggest understanding Exposure by Bryan Peterson. IMO when in aperture priority you can get 3 "effects" 1. isolation and bokeh(up to f5.6) 2. sharpness(between f5.6-f11) and 3. increased DOF(F11+)
1. Isolation and smooth bokeh. Portraits with that dreamy effect. Isolate a flower or other subject.
2. Sharpness f5.6-F8 Is where most lenses get maximum sharpness. Used when sharpness, color and contrast matter most. vignetting and other issues lessen as well.
3. Increased DOF F11 and above spot sharpness starts to fall off, but total DOF increases which can make the whole composed shot sharper. Used for macro, or landscapes if you also want foreground subjects
