I have the Tamron 90mm f2.8 and use it a lot. Excellent macro lens, second to last shot in this series was taken with the tamron 90mm, gives you a good idea of it's macro capability.
People have mentioned the AF shift on the Pentax. I don't own the lens, but I NEVER use AF for macro work anyways, in fact for realclose in work I move the camera in and out to put the focus emphasis where I want it.

NaCl(wouldn't trade for the Penatx or the Sigma)H2O

My "vote" should be construed more as "I have one and am happy with it" rather than I like it better than the others in the list, because I can't say that.

The only thing I might comment on is that switching from AF to manual. On the Tamron this is a 2-step manual procedure: 1. click the ring 2. switch the camera whereas on the Pentax it is automatic (ie. 0-step) and with the Sigma its ring disengages the AF internally at the same time as it engages the manual focussing (ie. 1-step). Not a big deal to me, might be to others.
I am deciding between the Pentax and Sigma (Tamron is almost the same price as the Pentax here). From what you are saying with the Sigma lens, you don't need to change to manaul focus on the body to use the lens in manual focus mode. All you do is disengage the AF on the lens. Is that correct?
