The irony of plastic use in DSLRs and other cameras

    What is the irony? The only part that would benefit from coming
    technology that will see plastic as a suitable replacement is the LCD
    which uses glass in it's construction. The only part of a camera where
    it would actually make SENSE to use plastic, and it's not available!!!

    Glass is not a requirement, but it tends to be more scratch resistant.

    A computer monitor is unlikely to be in contact with various objects
    that could scratch it, while a camera tends to be placed against shirt
    buttons, zippers, etc.

    Glass is a plastic in the true sense of the word.
    Hint, it was once sand, or something like it.

    Actually it's a fluid - a very viscous fluid to be sure, but
    a fluid rather than a plastic.

    I see he's also still confused about when to use it's and when to use its.
    Poor bugger.

    Well, not quite. I said it wasn't plastic in nature, but
    fluid. The reference you cite says "different views can be
    justified since characterizing glass as either 'solid' or
    'liquid' is not an entirely straightforward matter" and
    quotes a reference:
    http://math.ucr.edu/home/baez/physics/General/Glass/glass.html

    The conclusion says: "There is no clear answer to the
    question "Is glass solid or liquid?" ".

    It does appear to be a myth that glass flows, but that isn't
    what I said. Either way... it isn't a plastic!

  11. Scientifically speaking, ordinary glass at room
    temperature is a solid, no quibble. There is a
    clear change in heat capacity between a typical
    liquid value at high temperatures to a typical
    solid value at low temperatures. The transition
    is not sharp, but still represents a phase transition.
    My ex-colleague Peter Wolynes worked out the theory
    of all this.

    Is that why you bought one?

    $6000 for a rangefinder camera and a limited selection of focal lengths
    won't sell to very many people.

    So it would not matter if it was made of wood, you are still not getting one
    are you so just why would you care what it is made of?

    Then lock him up in a tower with a spinning wheel... and no

  19. The Irony here (Cue Alanis - it's like raaaaeeeeeeeeaaaaaaaaiiiiiiinnn)
    is that you don't have a Digital SLR and yet here you are day in day
    out.

    Get a camera or get a life
