Well since we're only guessing I'd say the Pentax is sharper with better flair resistance while
the sigma will have less distortion, if you can tell through fog. BTW the K 17mm looks like a
nothing more than a 24mm with lots of barrel distortion.

I understand that nobody may have personal experience with all of the following lenses, but from what you know how would you rank (sharpness & distortion) the following lenses?

Sigma Digital 18-50mm F/3.5-5.6

Pentax SMCP-DA 16-45mm F4 ED-AL



Also, we currently have

Fisheye Zoom 17-28mm f/3.5-4.5

Would the "digital" lenses offer much less distorted picture than the 17-28 'analogue' ;-) lens?
