Paul, I have the SMC-FA 28-80mm 3.5-4.7, which isn't very good in my view and doesn't have a good reputation on this list, and I have replaced it with the 24-90mm. This lens is great, and I can recommend it without any hesitation. At 24mm there a slight pincushion distortion, and at 90mm this is more noticeable. The sharpness is excellent, and I am not the only one on the list who likes this lens. With the Sigma you have a lens that has a stop or so more light, but it doesn't go to 24mm, which is a BIG difference. Some people have reported compatibility issues with Sigma lenses and Pentax cameras, concerns about build quality and poor service. I don't own a Sigma anymore, my old one was OK though.
There is one thing I don't understand from your question: what is it that you don't like about the lens? Is it the lack of sharpness, or..
