  1. Comedy is not your thing, don't quit your day job.
    I was addressing the lens reliablitiy, try reading what I wrote. Never
    mentioned the camera reliablility.
    You are talking about one incident, I know the thread you are talking about.
    My out-of-warranty camera years ago required a repair that was taken care of
    at no cost to me and I was offered a loaner until mine was reparied. I
    guess we can put you into the "Anti-fanboy" club. If it makes you feel
    good, go ahead.

    What was the Sigma lens you bought and didn't like?

    You're basically saying "Nobody else in a do-not-blame culture
    does blame Sigma (in a way visible to you), so they must be wrong".

    How do you know that the "specific conditions" aren't "higher
    prices than they would take for non-sigma lenses of that
    price point and features"?
    They seem to demand that lenses actually work. That's sheer
    arrogance. They should be glad that someone actually lets
    them buy broken crap. Right?
    What's interesting is that *you* ask credence to a "Sigma isn't
    bad" mantra on the basis that all the reports of variable quality
    and problems from Sigma aren't personal experience.

    Will you ask next to trust resellers whose resellerratings are
    unearthly with matching comments on the basis that we, personally,
    haven't been burned many times yet?

    Because that would shatter his conspiracy theory, and thus it
    just can't be.

    It's not comedy, it's the plain truth: you *can* fit all Sigma
    owners in the big blue room with the curious yellow ball ...

    A used 100-300mm zoom. After buying it, I discovered that the one mode I
    hadn't tested it with (aperture-priority, set higher than wide-open)
    caused an Err 99 on my (Canon) DSLR. Also, the grip started coming away
    from the body of the lens.

    Thanks for the warning. In general you should avoid those third-party
    lenese at all costs. There are often compatibility problems because the
    lens was designed for the cameras available at the time, without any
    knowledge of what future camera models with the same lens mount would be
    capable of (not only mechanically, but in electronic communication
    between the camera and lens).

    Every time I'm tempted to but a third-party lens I take a deep breath
    and think about the Canon lenses I have that have lasted 12 years with
    no problems at all, and decide that if I buy the more expensive lens
    then within a few months I'll forget that I paid more for a better lens,
    but if I buy the crappy lens I'll have to live with that forever.

    No, it's not an error to try to please everyone, it's an error to
    actually please everyone.

    Very true. And with an 85% failure rate, if that's true, they are at
    least displeasing the renter that is the last one to rent the lens when
    it fails.

    I have seen one, and apparently there were a few people that bought
    them. The list of issues with the SD10 was so long that it's hard to
    believe anyone would have chosen that over a Canon or Nikon, but
    apparently most of those customers had been using the Sigma film SLR and
    wanted to continue to use their Sigma mount lenses.

    The Foveon technology held great promise at the time it was introduced,
    but when they moved from three separate sensors to the stacked sensor
    with silicon color separation, it didn't work out.

    Most of their customers would probably not bother to research & find the
    info anyways <g>. That said, when I bought my only Sigma lens from the
    Calumet pro store in SF, the salesman sneered at me: 'you don't want
    that lens' as I handed over $800 or so... that's their 12-24 full format
    which has been one of my most used lenses and I'm quite happy with it.

    Details on that lens:
    It is the widest thing available for FX DSLRs ever. While not razor
    sharp, it is good and holds respectable sharpness to the corners very
    well. There is almost zero barrel/pincushion (except at close focus)
    which is great for architectural work. In many ways it is a well built
    pro lens, metal body & mount, smooth focus, etc. CAs are not reasonably
    well controlled considering it's acrobatics.
    It has slow max apertures. There was a (CPU?) flaw found for which I
    could have sent it back to fix where it messed up metering or something
    on certain camera bodies... never been a problem so I haven't bothered.
    The hood is a crap design with some kind of crap foam cushion to hold it
    in place that ripped off and it slides off all the time (argh!). The
    sturdy metal barrel is coated with some sort of powder coating flocking
    crap that has peeled off & looks like crap, near the mount. I treat
    lenses roughly, they get a lot of use and banging around in the bag.

    They have a bunch of very tempting and often quite good lenses that keep
    the big guys in competition. The Nikon 14-24 wasn't out yet when I got
    this and while stellar, it's more than twice the price and not as wide.

    I think the 14mm f/2.8 Sigma prime gets better reviews than the Nikon,
    or very close, or better in some respects and significantly cheaper. In
    this case the Sigma came years after the Nikon and Nikon now has a much
    better zoom. There are other examples of pro lenses like 300/2.8 where
    the Sigma performs very well for a fraction of the preposterous cost of
    the OEM. And old examples of Cult lenses from Tokina, Cosina, etc, or
    the Nikon Series E lenses that were supposed to be cheap and weren't
    given the Nikkor label but in fact were really great lenses. Lots of the
    third party Macro lenses are excellent.

    : I have to agree Paul, I got a Sigma 12-24mm back in 2005 to use with my
    : D70, and other than some initial operator errors resulting in
    : vignetting, which I have now overcome, it has performed flawlesly ever
    : since on the D70 & my D300.
    : I have since picked up a Tokina 11-16mm f2.8 which is wonderful, sharp
    : and fast and the Sigma isn't getting much use now.

    Where did you find the Tokina? Both B&H and Adorama have had it back-ordered
    for months.
