I'll try to find the best adjectives here. The focus ring is loose compared to my PENTAX-M 50mm F1.7 and goes through 45 degrees; but the resistance is constant. The zoom ring is smooth, heavy with constant resistance and also goes through 45 degrees.
It was cloudy outside, but I felt it was a good day to test the expected chromatic aberration at 17mm. I haven't done pictures with the kit lens in the same situation, yet, so I'm not posting the cropped corners, yet: so check out the photezone.de review. I tried the "cloudy" white balance. The attached photo is shot (hand-held) with F8, 1/30s shutter speed, ISO100, at 17mm (Av, autofocus, autoexposure +2.0).
BTW, this was the only blue sky I found.
EDIT: pentaxforums.com seriously degraded the sharpness of this photo. 
EDIT 2: Here's the flickr version:

Unless you're shooting an object that's completely flat and parallel to the sensor's plane.
How's it using the lens though? I mean, your experience with it. Is the AF fast enough, the feel of the zooming etc
