I think both of you are right, but just happen to be talking about different things.

I want to test one thing on my Pentax cameras tonight with a Pentax-M lens and then I'll post. I want to confirm one thing with Pentax-M lenses in manual exposure mode. I also want to confirm something that someone told me a long time ago about how to make a Pentax-M lens act like an adapted lens to get a sort-of (not so consistent) aperture priority mode on Pentax dSLR cameras.

But the "one" question I have is . . . if a Pentax camera suffers aperture block failure, then when you press the shutter button (to take a picture) when the camera is in manual exposure mode, does the aperture block motor actuate and attempts to stop down the lens? Basically, I want to know if the motor moves, even if it is not doing exactly what it is supposed to do. And . . . even if the cameras suffers ABF, does it still let you take a picture in manual exposure mode.

Take care & Happy Shooting!
