Pentax K-X with manual lesn Phenix f/1.7-22 50mm

vierx2007 · 05-14-2010, 12:50 PM

I purchased a new lens with manual focus out of curiosity. I set the aperture ring to permitted under custom camera setting to make the manual lens to work in my camera but when I started taking some picture it looks like if I choose f/1.7 compared with f/22 there is no difference. The picture always look like f/1.7 even though I set the aperture ring to f/22. Does anybody in this forum had the same experience from the past?

You have to use M mode for the aperture to work. Press the AV +- button to stop down and set the exposure.
