I think the important meaning of this lens is that Pentax is not yet dead in the eyes of other manufacturers. It has been quite a long time that there is no new 3rd party lenses released for Pentax and in the K-mount. Now, Sigma is there! And yes, now Pentax needs the support from 3rd parties! It is really true..

The reviews of Sigma AF 18-50mm f/2.8-4.5 DC HSM OS are not very pleasing:

Pentax 18-55mm ƒ/3.5-5.6 AL II SMC DA ~$160 http://www.slrgear.com/reviews/showproduct.php/pr...
The Pentax kit lens is also very good. Sharpness is on par with the Sigma, if not better - at 43mm and ƒ/5 it's tack-sharp across the frame. CA is well-controlled, better than the Sigma at 18mm, and comparable across other focal lengths. Distortion and corner shading are slightly better on the Pentax, again showing a point of zero distortion at around 35mm.
