    I love how Dpreview refers to it as "resin." Is that their P.C. term
    for polycarbonate scrap?
    This camera really is an inigma, Sigma apparently knowing they won't
    sell huge numbers of any of their offerings so the decided to see if
    the could recoup R&D costs at least by vastly over-charging for the
    body.

    Assuming of course that that is what it actually is. But even then if
    it has been recycled by blending with maleic anhydride grafted ABS you
    end up with a vastly superior material. You could probably use it to
    beat a metal-frame camera to death.

    i don't understand a reference to a rapid method of decoding.

    Nonsense. Which is why all pro cameras (and semi-pro) are made of metal.

    I don't care what it's made of. Sigma and their Foveon technology are
    both crap.

    Yeah, Rich. All polymers are identical.
    Well done.

  7. You mean like my Canon 7D? The Sigma SD1 is constructed the same way, plastic
    over a magnesium shell.

    And *all* the manufacturers are making their cameras out of supernova
    remnants. Why can't any of them use new materials?

    These are too expensive. ;-)

    Rich, beware, that "resin" is actually your ear wax that they have been
    stealing over the years.

    Its not nonsense. Polycarbonate is a seriously tough material and the
    recycled material I described is even tougher.

    Have you not seen the advertisments for polycarbonate windows where
    the window could bot be broken by a sledge hammer? How about:


    How long since anyone has had to replace a headlight lens broken by a
    flying stone? I know its nearly 20 years in my case. In the same
    period I have several times had the dents and chips in the hood
    repaired.

    Use your eyes, but make sure you are wearing polycarbonate safety
    glasses. :)

  12. boohoo booo hooo!


    about: Re: Sigma's $9700 APS camera's body is plastic,
    PLASIC!!!;

    "P.C.?" Don't only P.C. people say P.C.?
    ....like FoxLimbaugh&Co?
    Cuz it's more PC (manly) than saying "polite?"

    It's not manly to be polite these days, right?
    In fact, even saying "polite" is not PC in that crowd.
    Do tell, why do the hottest selling pocket
    pistols have plastic frames? Such as the
    Ruger LCP .380 and the Kel-Tec P3AT? ...long list....
    Ever heard of Glocks? How about Colts?
    Those are not for hunting or plinking.
    They are for saving and killing people.
    "Self-defense." CCWs to be specific.

    Perhaps mirror-bounce is worse than
    hurling lead to near the speed of sound?
    Or perhaps grabbing that shot with your
    digicam is more critical than with your
    weapon in a dark alley?

    Do tell!!!? Do tell!!!?

    I'm in the mood for a laff!

    In a dark alley I'd be more concerned with the sensor's high-ISO noise
    than the composition of the body.

    And most are concerned about paying $9700 for a camera that has a body
    like a D3100.

    Because it is MUCH cheaper to make them than machining metal
    components and they are easier to pass through metal detectors. Also,
    the components subjected to any kind of stress ARE ALL METAL.

    You mean the $5 glass headlights? A Cadillac plastic headlight cover
    is about $200 to replace.

    I think you mean _faster_ than the speed of sound (most center fire ammo
    breaks the sound barrier unless it is special sub-sonic rounds meant for
    use with a suppressor):

    speed of sound at sea level = 340.29 m/s = Mach 1

    ..380 auto: 380 MagSafe 380+ P+ Max, 52 grain, muzzle velocity 1,720 fps
    / 525.256 m/s = Mach 1.54

    9mm Parabellum: 9mm +p MG JHP, 115 grain, muzzle velocity 1,415 fps /
    431.292 m/s = Mach 1.267

    No, I mean the molded polycarbonate headlights which these days are
    just about standard on all vehicles, including Cadillacs.

  19. The D3100 has a magnesium skeleton?
