Could it be due to inaccurate calibration of the aperture mechanism of the
lens since it shares the traditional 'A' design (something difficult to
avoid because it would be too labour intensive to adjust them just right)? I
have tested all my lenses with Z-1p and found some of them open up the
aperture 1/3-1/2EV larger than they should be when the lenses are set to
'A'. Since exposure is critical with digital, the problem is obvious.

I am very disappointed in my DA16-45 which I bought with my istD. I cannot
count on it to produce useable photos. My first outing was to see my
daughter at an equestrian event on a bright day. Everything is washed out,
even close ups of my daughters face.
Is there a fix for this? Is Pentax acknowledging this? I do not want to
have to make additional settings to cope with this problem. I would like
to trade it in for a DA14. Anyone else notice this problem? I have
compared it to other lens and it is obvious.
