I would ignore Mr. Strat (who apparently is made out of money) and
check the lens database in pbase to compare output from these 2 lenses.
You can check out the Canon/Nikon/Oly etc. equivalents at the same
time to see if you want to spend hundreds more for them.

Good luck.

It's all made together to work together. Sigma's reputation for poor QC
is well known, and Tamron isn't much better.

That's a pretty broad generalization. I have the Nikon version of the
Sigma 180 EX macro and mine performs very well and is very well built.
If someone happens to get a bad copy of a Sigma (or a Tamron or a Nikon
or a Canon et al) they simply exchange it for another. No manufacturer
is immune to QC problems.

They recommend the Tamron. With Sigma, their 150mm macro is better.
Chromatic aberrations are a bit of an issue with the Sigma 180.

You realize that the Sigma lens you so cherish may not work with your
next digital camera. That's because they're too cheap to pay the
licensing fees and reverse engineer the electronics.

they also reuse rom chips, resulting in the exif indicating a different
lens than what was actually used. i know someone who was looking at
the new sigma zooms at pma a few weeks ago and took some sample photos
with the 150-500. the exif info reported it as the 18-200.

tamron macro lenses, however, are very good.

NO...they wouldn't do that.

You realize that if that was to occur I can send the lens back to Sigma
for a free rechipping. (I'd have to eat the shipping charge of course
so it wouldn't be totally free)
The fact that they're "too cheap to pay the licensing fees" saves me money.

They'll only rechip it once. Wouldn't it be wiser to buy a lens that
doesn't require after-the-sale tinkering?

from what i understand, they do that only once and with some older
lenses they may not do it all all.

interesting rationalization.

Some of those Nikon and Canon branded lenses may very well be made by Sigma
or Tamron. Does Canon make a lens specifically for each camera? No, it's
not "all made together to work together". Their lenses are made to work
across their camera line.
