I have the Tamron 28-75 too. It is constant 2,8 and quite useable at full opening at all focal lengths.

I have the Sigma 28-105 f/2.8 - 4.0, which I bought over the Pentax because it's a faster lens at wide angle. Given what I'm reading, I'm glad I got it; it's now the only zoom lens I own. I would like a something like a 28-75 or something else in that range with a constant aperture.
