Good point. I have no idea. It only occurred to me this past weekend that I might want something in this range. I've never heard of the Pentax 20mm. Could someone please post some samples? I checked Pbase and Google but I couldn't find any examples of anything from this lens. It is attractive if only because of the size - the Sigma is rather large. > If yes, then you have no choice - go for the Sigma.

Thanks for the info! The samples from that one look great, but I think he is actually thinking about getting my Sigma fisheye. :) Amita
