My Sigma 28-105 lens bit the dust today. Well, maybe it didn't bite the
dust, but it certainly broke. In the middle of shooting, it became unable
to stop down the aperture *if* the lens was at 70mm or longer. Under 70mm,
it works just fine. Above, nothing. If I stop it down and then extend it
past 70mm, the aperture is stuck closed (instead of opened), and not even
taking the lens off of the camera will release it - until the lens is back
down to under 70mm. A call to Sigma's tech support confirmed that the lens
will have to go in for repair (still under warranty - only a couple of
months old, with pretty light usage). Estimated repair time 3 weeks, plus
transit.

I had planned on avoiding Sigma in the future for other reasons, but I
guess I found yet another reason today.

On occasion I've been tempted by Sigma lenses, but I remember the quote:
"There is nothing in the world that some man cannot make a little worse and
sell a little cheaper, and he who considers price only is that man's lawful
prey." -- John Ruskin<!-- ~MESSAGE_AFTER~ -->

The sting of low quality is remembered long after the sweetness of low
price is forgotten.<!-- ~MESSAGE_AFTER~ -->

Of what I've owned:

Bronica (3 different) - no
Praktica (1) - no
Petri (1) - no
Zorki (1) - no
Soligor (1) - no
Vivitar (1) - no
Hanimex (1) - no
Spiratone (1) - no
Schneider (2) - no
Nikon (12) - no

So, I guess lens failures are rare as many of the above are 30 years old (or
even older) and still working fine. As for your Sigma theory...I'll leave
that to those who've owned one.<!-- ~MESSAGE_AFTER~ -->

Well...I have a Canon EF 28-70mm f/3.5-4.5. It's more than 10 years
old, and I've owned it for 5 of those. It works perfectly. I also
have a Canon EF 35-135mm f/4-5.6 USM. Again, over 10 years old.
Works perfectly.

I made the mistake of buying a Sigma 28-300 hyperzoom. At 15 months
old (and out of warranty), the aperture stuck, in a similar way to
the OP describing. I must have only put around 5 rolls of film
through the camera with that lens on.

I'm going to be *very* wary of buying Sigma again.

Actually of all the many lenses I have owned over the last 30 years I have
only ever had 4 go faulty.

1 Bronica, 1 Hasselblad, 1 Canon USM EF and yes 1 Sigma.
