I've had an older version of the same zoom for some years now, and it has been extremely good, both on film and digital. Distortion is an issue on film at the widest setting, and sometimes it would balk at focussing, but otherwise I'm very satisfied - despite Sigma's reputation! On the other hand, a Sigma 28-80 I acquired as part of a kit was absolutely woeful - flat, unsharp, and everything wobbled.

Sharp all over the frame. I've been using the EX 4-5.6 10-20mm for some years. Actually always on the K-3. But the new 18-35mm is MUCH sharper - not only in the centre, but all over the place. Man it's nice. It is even possible to buy a USB-doc in order to adjust focusing. Very good for panoramas too: https://www.flickr.com/photos/bladt/15952210569/ https://www.flickr.com/photos/bladt/16137546972/in/photostream/ I guess It's my standard zoom lens now :-) Regards Jens -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
