Opinions on the Tamron SP AF14mm f/2.8 Aspherical?

Anyone ever use the Tamron SP AF14mm f/2.8 Aspherical? Any ideas on the price premium over the PentaxDA Fixed 14mm f/2.8 ED (IF)?

I'm looking for a UW and can't decide on what gives me the best price / performance ratio.

I've had one for a while now. It's nice, sharp, and is relatively well-controlled for both distortion and CA. (I say *relatively* in comparison to other 14mm lenses - it has both distortion and CA.)

It is a full-frame lens, and I think the price premium over the Pentax is mostly because of all that extra glass supporting it. The only real in-depth comparison I've seen is from Klaus over at, who reviewed them both. The Pentax seems to have less distortion and less vignetting. My copy is probably sharper than the one Klaus tested.

A few of mine (click for the bigger version):

Those are nice, I've heard some negative things in the past about the Pentax and I'd never heard anyone that had the Tamron. I think at this point I'm looking at the 10-20 Sigma.

I saw the thread title and I thought "Sean has that lens....."

I loved my 10-20mm so much that I ordered one for my 40D now.....
