What does YMMV mean?
Sorry to hear about you bad experience with Sigma, Carlos. As you can see,
not everybody agrees on this :-).

My experience with Sigma hasn't been completely negative. The Sigma
lenses I've had, or used, have ranged, optically speaking, from
acceptable to good. But their electronic compatibility with Pentax AF
bodies has been another thing, and their mechanical quality, also lacking.
If you do some research, you will find that bad quality control issues,
electronic incompatibilities, and AF problems are not uncommon among
Sigma lens users. If I remember well, Mark Cassino reported that in low
temperature, the iris of his EX 70-200 2.8 froze open. He compared it
with the Pentax FA* 80-200 2.8, at the same low temperatures, and the
Pentax didn't suffer from that problem.
I have also had Tokina and Tamron AF lenses, and in my view they have
been more reliable than the Sigmas I've owned or borrowed.

Carlos
