Does the A setting work well? There has been some reports in the reviews of it not working.

I've never had a problem with it, though i shoot manual a lot. I just tested it against my DFA 100mm Macro and got the *exact* same readings in a few different lighting conditions.

Usually people complain that the aperture ring is stiff, but this one doesn't seem too bad.

I'll post examples over lunch.

Attached photos all shot on K-5, Av mode, comparing Pentax 100mm DA-F Macro vs Sigma 50mm Macro, Center Weighted Average metering, no post other than resizing the images. I moved the camera closer for the 50mm photos to make the Field of View the same. Marginal (1/3EV) changes in shutter speed in 2 of three settings.

At the moment wondering why I paid so much for the 100mm...
  • 50mmA = 1/20 at f2.8, ISO 400
  • 100mmA = 1/15 at f2.8, ISO 400
  • 50mmB = 1/2000 at f2.8, ISO 100
  • 100mmB = 1/1600 at f2.8, ISO 100
  • 50mmC = 1/200 at f8, ISO 100
  • 100mmC = 1/200at f8, ISO 100
