So I got couple toys to play with for my K10D:

Pentax 50-200mm F4-5.6 for my Zoom (bought it for a great price ~150)
Tamron 17-50mm F2.8 for my Walkaround lens

Metz 58AF Flash (Deliver today)

So I'm looking for a wide angle now that can capture indoors rooms as well as landscape.

I've been eyeing the Sigma 10-20mm for the extra 2mm over the pentax 12-24mm and cheaper price, but also the Pentax Fisheye 10-17mm for a whole $100 cheaper than Sigma mentioned.


As an amateur, I'm torn between the two. I'm leaning more toward the "wide angle look" instead of the barrel distortion of the fisheye. But the fisheye is kinda cool, and can sure capture a lot more of a closed room.

What do you suggest base on what you've been using more often?

Thanks.
