Originally posted by Sailor When I saw the radically overexposed shots from my K28/2 in M mode, I tried my A*85/1.4 using the aperature ring (instead of what one normally would do: set the lens to A, and use the e-dials on the camera). I saw the same extreme overexposure.
A few hours later, I was playing with my FA35/2 and decided to try it in M with the aperature ring. Every exposure was spot on, and I wondered why the aperature ring on an FA would behave differently than that of a K or A lens. Then it hit my aging brain; right after I "tested" M mode with the K28 and A* 85, I noticed the battery was low and put in a freshly recharged one. So with the reinvigorated battery, I tried the 28 and the A* with aperature ring and both lenses (with green button or stop down lever) yielded spot on exposures in M mode.
So, was the battery low and causing erratic behavior or did removing the depleted battery (and installing the new one) reboot the system so that it could - as my Dad would have said - straighten up and fly right?

Pass my a serving of crow.
I got home early enough this evening to retry my K10D and the K28/2 I mentioned in the OP outside in natural light. Sorry to say that it overexposes at lens openings of less than f/4 - as others are reporting. Experiments with my FA35/2 using the A setting and the aperature ring indicate that the overexposure is about 1EV. Guess I was fooled last night by the low light conditions (also I was "testing" durng the cocktail hour).
Anyway, sorry for the misleading reply quoted above.
