This lens covers a handy range of focal lengths. At 24mm (equivalent to 35mm on a 35mm film camera) it replicates the popular moderate wide angle that is handy for car shows, architecture, landscapes and group shots.
Go down to 12mm, and you get a very wide view, great depth of field, and essentially no barrel distortion.
Although there is some overlap in the focal length of the Pentax 10-17mm lens, that one has the pronounced "fisheye" distortion (though not too much at 17mm), while the 12-24 maintains straight lines (it's "rectilinear") though if you are tilted up (or down), your subject will lean in (or out).
More expensive than some lenses but less than others, I say it is worth it. Its constant f4 maximum aperture is part of the cost (and weight).
It is a little bulky, not lightweight, and has a rather large lens hood, so you might have to rearrange your bag divider...

Pop Photo (Apr-06) designated this lens the Wide Winnerfor its superb performance on objective tests. I agreed whenfirst documenting home inventory, or picturing dark churchinteriors.Once in the field, I became disturbed by the pronouncedchromatic aberration ['purple fringing'] of trees or powerlines outlined against an overcast sky. To ensure thiswasn't a user or equipment error, I took manually focusedRAW test shots (with a K10D and lens hood) at f4, f8 and f16each at 12mm, 18mm and 24mm and examined them at 100%magnification in Lightroom. To clinch matters, an identicalshot with the 100-buck kit zoom lens at 18mm and f4 yieldedfar less edge fringing than this 13-element costly zoom,boasting high-dispersion glass and aspheric lensconstruction. Only a 10-buck plastic disposable camera hadmore notable CA!Its otherwise sterling performance (crisp clean images,minimal vignetting, and indiscernible linear distortion)cannot compensate for the inexcusable edge diffraction.

Pop Photo (Apr-06) praised this lens as a "Wide Winner" for spectacular performance on bench testing: excellent image sharpness and contrast; imperceptible distortion ["best of breed"]; and barely notable vignetting at the short end. I can add breathtaking color, crisp contrast and ruler-straight linearity to that list. At first glance, a 2X zoom doesn't sound impressive these days - until you realize that this parafocal zoom sweeps an incredible 100 to 60 degree viewing range, that's just perfect for cramped interiors, group pictures or landscapes. This zoom is a landmark of stellar engineering: combining extra-dispersion glass and aspheric lens elements into flagship "great glass".
But a finely-tuned optical engine performs optimally only if all cylinders fire in unison ... at daylight trial, I noted a hideous 'purple fringing' [chromatic aberration] of trees and power lines outlined against an overcast sky -- something was badly remiss. Rather than returning the lens, I packed it up
