Have you had a chance to compare its IQ against the IQ of Version 1 (f2.8-4.5)?  Excluding the incoporation of OS, which not relevant to Pentax users since it is excluded from the lens and done in-body, is it worth upgrading from an optical performance perspective?

Thanks

I don’t understand why photographyblog rating the value for money is as 5. It’s not a cheap lens, and even not as sharp as Tamron 17-50mm 2.8 Non VC.

I’ve been shooting with one of these for about a year now as an upgrade from the Canon 18-55 kit lens,and have been very happy overall. I agree with Nam that it’s not a cheap lens, but I also agree with the high value-for-money rating of the reviewer.. it is a significant step-up from the kit lens in all respects, and as one who uses a polarising filter a lot, the internal focusing is a huge bonus. The closest Canon equivalent is the 15-85mm which also produces very crisp images, but it’s also almost double the price of the Sigma, as well as only fitting the APS sensor bodies.
The one shortcoming of the Sigma is the focus ring, which travels through a narrow arc of approx 50 degrees, making fine manual focus adjustments quite tricky.
Apart from that, it’s a very attractive lens, and I’ve not regretted buying it for a moment.

I don’t understand the use of many of the sample images with the Exif information posted. Shot information showing a zoom setting of 106 mm on a 70 mm max lens. Are you saying these are cropped? Normally we say 70mm 50% crop or 100% crop. It is confusing and not sure if the images are from an different lens not representative of the experience expected with the 17-70 mm Sigma.

Also the photos of the bikes in the bike racks….24 mm @ f/2.8 and 51 mm @ f/3.5. Maximum light is at 17 mm and reduces through the zoom to f/4.0 starting at 50mm. At 24mm it should be around f/3.3 and the 50 mm+  should not be less than f/4.0.

@Bob Komjathy this lens is for APS-C bodies,so you need to multiply the focal length by 1.6 (or 1.5 on Nikon bodies), hence the 106mm.
