I'd go for the 180mm. I really want the Tamron, but it's not for Pentax. So I'm thinking about the Sigma. But a 105 with 2x converter isn't bad either. And I already have that.
The focal length is just for distance really. Since you have a 50 already I mean. I have a 105mm, and want more distance. I thing I would want the Pentax 35mm 2.8 Macro as well to have 35mm and 180mm, then maybe sell the 105, or just 35mm and 105mm-2x converter.
