Pentax DA 10-17, Sigma 10-20mm f/4-5.6 EX DC HSM, or Something Else?

Like GPGeneralPhoto...I also bought both but told myself I would only keep both for 6 months and then I would choose. After six months I kept the Sigma and sold the Pentax fisheye since the rectilinear aspect was more important than the fisheye and I didn't want to keep "de-fishing" photos.

Overall, I made the right choice...but I confess that sometimes I really miss the Pentax 10-17 because it is such a fun lens.

But be warned...bring that lens out at a family gathering and the women flee the area while the children will flock to you to pose for pictures.
