I just got my 16-50, and after a few test shots, it seems like a good copy. a few questions though...

1) Is the zoom ring really a little stiff, especially around 28-35mm? Unlike the 50-135 that's smooth? (Is it because of the weathersealing in the front part of the barrel where the lens extends?)

2) Focusing wide open is sharp at 50mm, but when I focus at 16mm, it's a little soft. Is this normal when used with the K10? (as with my 50-135, focusing is soft at the wide end, whereas focusing at the long end is hella sharp... but when I tried the 50-135 on a k20, it was sharp all the way.) Is this a K10D only issue?

Thanks!
