My guess is slow/sticking aperture blades or lever.

Troubleshoot as others have suggested. You may also want to try turning the electronic shutter off in the menu. Some older lenses can't adjust the aperture quick enough and it can cause some anomalies if that is the case.

Your issue looks similar to what happened to my 70-210 beercan over the summer. The aperture lever was sticking, causing slow to respond aperture adjustments. Moving the lever several times using a pin or toothpick fixed mine since there was no oil on the blades to cause the sticking to occur.

Thanks Paul, I will do that. Could this also explain the "white haze" that I see in the middle of the photo and the lack of sharpness?

Should the aperture lever "spring" back to the closed position? It does on my 16-50, however on the Minolta I have to manually move it back to the closed position. Here is a picture (of the same pathetic tree) where I set the aperture to f22...

If this is f22 for same speed, the blades or pin is sticking or bent....

This is f22 at 1".  I am in A mode.  The aperture level does not spring back at all.
