I don't know why either (for sure) but I suspect that it was a cost cutting move. Electronic operation of the aperture means that that manufacturer no longer has to build the mechanisms into the lens that communicate the aperture setting to the camera. It also seemingly eliminates an entry point for dust, moisture etc. If it makes the lenses cheaper to manufacture then Pentax will have to follow suit to compete. I've used a Canon camera and lenses and I didn't miss the aperture ring at all. The thumb wheel on the back of the camera was quite easy to manage. > Personally, I don't miss the aperture ring much. I wouldn't miss it either as long as there's some other way to set the aperture. Tom Reese
