Very good "walk around" lens, August 1, 2007 By This review is from: Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens for Pentax and Samsung Digital SLR Cameras (Electronics) Better than the standard kit lens for a few reasons; it's a little faster, a little wider and much longer, good macro capability. It's effectively a 28-105mm zoom (35mm equiv.), great for general purpose wide angle work, and a decent portrait lens at the tele end. Nice and sharp. You can get more pure speed by looking at the 16-50 2.8 constant aperture lens Sigma makes, but you'd be giving up a lot of zoom and paying somewhere around a 40% premium to do so. You can get more tele reach with the 17-125 that Sigma makes, or that monster 18-250mm, but you're giving up speed and close focusing. So just buy it already, along with a good long tele zoom (say, 55-200?) and a fast normal prime (say, the lovely Pentax 50mm f1.4).
4 of 4 people found the following review helpful Excellent zoom that is as sharp as my prime lens, December 14, 2007 By Petiteface "gadget lover" (Austin, TX) - See all my reviews Amazon Verified Purchase This review is from: Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens for Pentax and Samsung Digital SLR Cameras (Electronics) I have a Pentax K10D and a Pentax SMC-FA 35/f2.0AL lens. I bought the sigma 17-70 lens to meet my basic walkaround needs based on the recommendations given by various folks on the Pentax SLR forum at dpreview. I received this lens and I am thrilled with the quality of the photos even wide open. While the 2.8 wide aperture is only valid from 17-21mm, the lens is really sharp in the entire range.
I have compared the performance of this lens with my 35mm prime at equal 35mm and equal apertures and the photographs are just as sharp with more pleasing (warmer) colors. The sigma lens is also made in Japan and the construction quality looks really good. The only two downsides are 1. The lens does not balance well on the camera (even with the BG2 grip on) so one has to place the camera LCD side down. 2. The zoom is a little stiff and one has to turn in the other way (counter-clockwise) to extend the focal length (unlike my 18-70 Nikon zoom)
Vey highly recommended. 47th... Read more

Nice walk around lens, excellent color, January 23, 2008 By This review is from: Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens for Pentax and Samsung Digital SLR Cameras (Electronics) I got this lens about a month ago and it has been on my Pentax K10D for most of the time. The lens produces sharp pictures with nice colour and contrast in daylight and covers a good range from wide angle to medium telephoto. The only issue is that f2.8 is only available till 21 mm. Not the best choice if you want to shoot in low light.
