Which one to buy: Tamron SP 180mm F/3.5 Di Macro or Sigma EX 180mm F/3.5 DG Macro

Tamron SP 180mm F/3.5 Di Macro
Sigma EX 180mm F/3.5 DG Macro

I have found those which are not so different in paper but what do you
think? Yes I know that the Tamron is cheaper.

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. :-)
