How to get the most out of my DA* zooms?

Hi all,

I picked up a 16-50 and 50-135 and I've been kind of disappointed.

I've seen stunning shots so I know it's me, not the gear, but I don't get the kind of results I'm used to with my 35 and 40 Limited. I know part of it is the weight (I think I've gotten shutter speeds as slow as 1/6 without significant shake when I'm propped right), but there's got to be more.

What can I do to learn how to love my new gear?

If your body supports micro AF adjustments make sure the lenses are properly calibrated to eliminate back/front focus.

I found that UV filter in front of my old copy of 16-50 caused image to degrade quite visibly. Also older camera body model like the K-x may be plagued by front/back focus problem. My K-30 seems free of FF/BF.

So I'm using this guide; I've only tried my 50-135 so far, and it always hunts, even when in AF.S, and even if the image is already in focus; is that normal?

Edit: My 16-50mm's SDM died, and is listed in the marketplace.

Doesn't seem right that it hunt so much but I have not tried that screen method.

BTW you know you can convert your broken SDM lens to screw drive, right.

There is a thread in the lens forum.
