Either "green button" in M mode or you can cut off the aperture lever and
use it in AV mode. Can also be used completely manually.

Subject: Other than A
Hello
Inspired by "Pentaxians" - a Facebook Group, I bought a Pentax-K 2.8
120mm lens. It's supposed to be excellent according to Pentaxforums.com
(rated 10).
But now I can't get i t to work properly.
I did set the "Pentax Function" to "Other than A" - shutter will
release, disregarded the apeture is not set to A.
But the Aperture is only stopping down in M - Manual Mode.
Did I miss something?
Does the K-3 not have an aperture simulator????
Which Pentax camera was the last one to be equiped with one?
Is there anything I can do to make it work in Aperture Priority mode?
Or - how do I measure light - determin the "right" exposure?
Thanks in advance
Jens, Denmark
