The 20-40 isn't wide at all, I'd skip it (it's intended for a Full-frame camera) and the 16-50's a general purpose zoom. This is one case where I'd unabashedly recommend the Sigma. The 10-20 f3.5 is simply a better lens than Pentax's good but not exceptional 12-24 and the Sigma's cheaper as well. The only lens in this range I'd consider over the Sigma is Tokina's incredible 11-16 f2.8 but it's not available in Pentax mount. Don't get me wrong, the 12-24's a good lens (as is the Tokina 12-24 where the design originates) but the Sigma is definitely better. It's wider, faster, sharper and has better AF. -Adam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
