Pentax 10 17mm f 3 5 4 5 vs tamron 10 24mm f 3 5 4 5?

The two are both APS-C zooms that start at 10mm with f/3.5-4.5, but they're built for different jobs.

The Pentax HD DA Fish-Eye 10-17mm f/3.5-4.5 ED is a fisheye. It's a creative tool for bending the horizon and getting the whole sky into one frame. It has autofocus, isn't stabilised, and mounts on Pentax K.

The Tamron 10-24mm f/3.5-4.5 Di II VC HLD is the one I'd pick for everyday wide work. It reaches 24mm, which covers more normal landscape scenes. That's the classic wide-zoom job in my landscape guide.

If you want straight lines and a usable everyday wide, go with the Tamron. If you want the fisheye look, the Pentax is the one.
