This is really wierd, I just switched lenses for the first time in maybe 2-3 weeks and ran into a really weird issue. My K-30 is always stopping down to the minimum aperture on all of my lenses except for the DA 16-45. The optical viewfinder still looks normal and wide open but when it snaps the picture or if I switch to LV it closes the aperture down all the way.
It takes the picture with the exposure that it should take at the f-stop that is set but it always comes out under exposed unless I set the ap to the max.
Attached there are three pictures of the same seen taken in AV with the maximum aperture set using three different lenses.
DA 16-45 @ 45 mm Av f/4 actually at f/4
DA 21 mm ltd Av f/3.2 actually at f/22
Sigma 50 mm Av f/1.4 actually at f/16
Has anyone else ever had this happen and if so how do you fix it?
