waideangle choices for the SD1m?

[Spanik]

I'm fairly well decided to get a SD1m while they are still available. But what are the wideangle choices? If I look at the lens lineup then there is the 24/1.8 which is usable as a 35eq. But all those below 24mm seem to be fisheyes.

Aren't there any rectilinear wides wider than 24mm? I'm looking for something in the 16mm to 14mm range.

I use the Sigma f/3.5, 10-20 mm DC lens. If you don't need something that wide, the 18-Sigma f/1.8, 18-35 mm lens is excellent.

I was looking for a prime. But the 18-35 might be an option. Rather large and heavy isn't it?

The Sigma mount is a pentax one isn't it? Any options that way?
