A classic high-plains shot with a twist. Well done.
(And a perfect set up for a Wile E Coyote an' the Roadrunner scene, eh? :D )

Now that's a nature picture. Subtle, like all good natural subjects. And I'd bet it would stand the test of time if posted where folks had the time to give it a second look. I could watch ghostly-grouse cross that patch of snow forever!
Brought a smile to my day. Well done.

I had a Sigma 10-20/4-5.6 in hand for a few weeks and I agree that it's earned its reputation and place in its class. But I also stumbled on an irresistible deal on a Tamron SP AF 10-24 which is generally given lower marks in reviews and third hand advice.
These two lenses were my introduction to the UWA focal length range after all this time so I don't have an educated approach to the nit-picky UW stuff. After two days in the field using mostly available light and 200+ images each, most of the time I couldn't reliably tell the difference between the two lenses on the monitor without referring back to the originally recorded SD chips. There were just too many external variables that overrode any individual attributes of the lenses for me to prefer one over the other for overall optical quality.
I'd like to say I thought the Sigma might have been a tad sharper at the short end but its just as likely I was being swayed by the opinions I've seen on-line. Both lenses seemed to have situations they were particularly suited for and the extra 4mm at the top end made a noticeable difference for me with the Tamron.
Here's an image from one of them, picked because I had identical shots for both lenses and the color was almost exactly the same in both files. This has just been cropped with a bit of compensatory sharpening and exposure adjustment to match the two back-to-back JPG exposures in a K200D, ISO 400, 20mm, F 4.5 & 1/250 sec.
I couldn't tell one from the other after minimal PP-ing so the decision as to which to keep was based on functional attributes and cost. I'd have been pleased with either lens and the learning curve will be fun as I've come to UWA late in the game but I kept only one of 'em (for a change!).
Which one? Well, that's sort'a my point here as both were nearly identical in practical use. I'm gonna enjoy that extra 4mm regardless, but then, this IS a Sigma thread, huh?
