I have both lenses. The Pentax 10-17 Fisheye is a fun lens, but can introduce quite a bit of distortion above and below the horizontal centerline, when held normally. However it has a 180 degree field of view that is great when needed.

The Sigma has much less distortion, but only about a 90 degree field of view. The Sigma has much less CA (purple fringing) as well.

Both are nice lenses, when used appropriately.
