I've used (and just bought) a Sigma 28mm lens (not this particular model)- it's wide, but not super-wide. It won't be as wide as you think if your experience was with a full-frame camera - where 28mm is pretty wide.

I wouldn't trust that description -- the built-in filters in those things can be prone to getting hazy, and you have to choose one of the filters or it won't focus correctly. If it was the 18mm, which is quite rare, maybe go for it, but there are plenty of decent 28s to choose from without the gimmicky internal filters...

With the APS-C 1.5 crop factor of the K-r, a 28mm lens has roughly the same view as a 42mm lens on a full-frame camera. Barely wide angle. The roughly equivalent wide angle on the K-r is 18-19mm.
