Happy enigma about crappy Sigma

    My Goodness! Had a Sigma 50-500 in my hand in a store, when I thought I saw
    a small scratch. I played a little with it, but a hole piece of the matte
    plastic came of and showed the shiny plastic underneath!
    Here they sell for 1300,- euro, or about 1800,- US dollars. For that amount
    of money they can not even give it some real plastic?

    What a crappy company!

    at least it's not held together with double-sided tape, like some older
    sigma lenses were. really.

    There is nothing more objective than direct personal experience, and
    I have owned a Sigma lens (puchased new) which contained a front
    element connected to the rest of the lens body by sticky tape. It
    eventually came unstuck.

    A few years back there were reports all over the net about Sigma
    lenses simply falling apart in their owner's hands. They were
    assembled with tape inside holding major sections together, and the
    tape was failing on a regular basis.

    Oh no...you're just another Sigma hater with an anti-Sigma bias.

    That's a bit harsh, although their quality can be quite variable ;)

    I once bought a 135-400 (istr) via mail order. Upon checking it I saw some
    loose particles of black plastic (like small slivers) deep between one of
    the element groups.

    Of course, I rang the company (Warehouse Express) who were happy to refund -
    but who also seemed a bit surprised that I was making a fuss. They seemed
    to regard this level of build as par for the Sigma course.

    On the other hand I've had some really excellent Sigma's - including the
    105EX and the cheapie 70-300 APO, so buying Sigma means paying your money
    and hoping for the best.

    I was under the impression that they were improving.

    Regards

    And regular one sided tape, I've seen it in one. Not to mention their
    higher end lenses sometimes cost as much as OEM stuff for the same
    f.l.s and speeds. At the local camera stores who sell this stuff,
    there is palpable hatred of Sigma products.

  10. I actually have two (older) Sigma lenses (both purchased 2nd hand on Ebay)
    -- a 28-70 AF f2.8 and a 70-210 AF f2.8 of which I am happy with. Both seem
    solidly built and perform well mechanically and optically. But my total
    investment is under $400 for both.

    My feeling was that the quality has gotten worse not better but other than
    my older lenses, and recent comments here and in some recent reviews I have
    not much information to base that opinion on.

    Not sure I would buy some of the higher priced current new Sigma stuff (not
    sight unseen and certainly not when new OEM equivalents are the about the
    same price).

    Is it possible that those were counterfeits of Sigma lenses?

  14. That's fairly common with discount brands of anything - cameras, TV,
    cars, home electronics, etc. The designs are less robust and the
    manufacturing quality is lower.

    Making a 50-500mm zoom range work, even marginally, is going to require
    precision ground glass. That's why the lens is so expensive despite the
    build quality.

    Has anyone ever gotten a Nikon 55-200 to find focus in under 7 minutes?

    Sigma always seemed to have the knack of making sure that the review
    samples submitted to magazines worked perfectly.

    I worked in a sudio and we bought a Sigma 28-70 f2.8, took us 3 lenses
    to find a sharp one, then we were shooting wwith it when the
    photographer tripped over the wire to the flash pack, a 2 lb head
    falling with a light weight light stand sheared off the front of the
    lens, clean shear.
    But the funniest cheap camera construction was with a Yashica 2 1/4
    twin lens. I was working at a college in charge of a about 100 Yashica
    twin lens cameras that student could take out. A couple were always in
    the repair shop, the camera repair guy called me and asked me to drop
    by. He had one of the cameras totally disassembled, one of the side
    panels was off and there was a color graphic on the inside of the
    panel, obviously something commercial. A friend of the repair man said
    it was from a Japanese beer can, useful recycling in the ealy '70s.

  18. They've also managed to get every one of my lenses to work perfectly too.

    Someone who wants to make a $290 profit on a $300 lens.

  20. Actually, 3M VHB ("Very High Bond") tapes have been in use for decades
    to bond all sorts of things, so their use in a camera lens is not that
    surprising.

    Done properly, it's a fast, clean, low-waste method of construction, and
    it's used in everything from cell phones to skyscrapers.

    However, it is CRITICAL that the surfaces be prepared properly, and the
    correct tape (there are hundreds) be selected for the materials to be
    bonded together. If that gets screwed up, it will almost certainly fail
    at some point.
