For a guy who takes stuff apart all the time, I can't believe you can't solve the A50/1.7 aperture ring problem. The leaf springs that push the A button out will fall off the lens and foul the aperture ring movement. I've repaired it on the A28/2.8. The repair is trivial, the dis-assembly isn't tough...just keep track of the little ball bearing that makes the clicks for the aperture stops.

Most Pentax lenses very between very very good, and fabulous. One or two are only very good, none are crap.
Ok, here is one - A50/1.7. That damn aperture ring just won't turn smoothly. I had 2, and both had the same attitude. Not happy.
