They do not operate with the precision of the old designs and do not inspire confidence.
Presumably newer models have improved. But you can keep them!

Back in the days of manual focus I was always making minor adjustments to my focal point, to alter the depth of field. Forward or back depending on the image, AF can't guesss what you want to do. You can't expect an AF system to make such adjustments, if you want that kind of control go to manual focus. That has nothing to do with Pentax by the wy. That's just AF. However for wildlife or birds in flight AF can make adjustments much faster and accurately than MF. Out in my blind MF is slow, unpredictable and will cost you many images. So, I don't know what you shoot, but my guess is, your opinion is based on stationary objects. The fact that AF is an amazing thing, doesn't negate the need for MF where really tight control is required. The problem being, you're asking AF to do more than it's capable of. When I'm out in the field shooting mushrooms etc. MF using "live view" is every bit as good if not better than my old split image focussing screen. You just need to learn to use your camera to it's strengths.

Originally posted by E-man I have no problem with well-crafted plastic lens barrels that can save weight but I draw the line at plastic lens mounts. I have a couple and they just feel cheap and flimsy to me. I just prefer the perception (and yes, I realize it's mainly just perception) of solidity that a metal mount delivers when it clicks into place. Plastic on metal just doesn't get it for me.
If you are going to use that criteria to select lenses, you're probably going to miss out on a few lenses you might otherwise enjoy.
