Originally posted by Adam All Pentax cameras should behave this way AFAIK- you just need to allow the use of the aperture ring through the menu.
I was curious about it but wanted to wait until I had a Pentax with a stuck solenoid in my house.
Today a K-50 arrived, typical symptons.
I tried it the way member m42man suggested (lens: F50/1,7) and came to the same conclusions!
It works exactly the way he described.
Then I took an already repaired K-30, set it on AV but the lens not on A but a chose aperture:
Opposite you thought it did not work (wait, more will come!)
It would not fire when I changed the A-ring to any other position than A.
As soon as I press the the release button, the display goes off, as if there would be some kind of shortage and the K30 would not fire.
Back on A and all is fine.
So I tried it with the K5II and suprise: It works the same way as the K-30 with the stuck solenoid!
I then opened the K-50 for repair but then placed the battery back in and then the F50/1,7:
The solenoid does not actuate at all.
Then I exchanged the solenoid (white solenoid): All was working as usual and as it should.
I then tested it again in AV mode but the lens not on A but a chosen aperture and very strangly it works .. and yet, the solenoid does not actuate!
So I have no explanation at all but have to wait until further K30's or similar arrive here and I can test.
