Carl,

I'm very interested in this lens, because it is so good and cheap compared to de sony. The sony is probably somewhat sharper, but I don'nt think my 10mp can resolve that. Anyway I've read that with the tamron getting to 1:1 focus the aperture jumps to 5,6 in stead of 2,8. Is that so or is the DOF so think at 1:1 that you have to go to 5,6 and up? Does the sony do this also?

Cheers, Robert ... would like to see a test with the sony version.
