I have the Tamron 90mm f2.8 AF and the Pentax F 100mm f2.8. I prefer the Tamron for its handling, particularly the large focusing ring, as I'm often used MF for macro. I can't really see the difference in image quality, and when I tested them the Tamron gave higher contrast. The Pentax did have a fungus problem at the time (since fixed by Pentax), so I should probably test them again.

Pentax glass experts, It looks like I might finally be able to buy a macro lens soon. I was wondering, what's your favorite Pentax (or other) macro lens and why? It could be AF or MF. Thanks, Amita
