    No contaminated CHINESE plastic here.

    "It's the body's job to enclose and protect the cutting-edge
    mechanisms and indeed the potential of the Olympus digital SLR
    flagship. After countless tests and lengthy deliberation we finally
    arrived at the consensus that, due to its unparalleled durability,
    magnesium was the best material to use. Offering a solid feel and
    enabling highly airtight design for outstanding dust and splash
    resistance under severe environmental conditions, it was the most
    suitable material for the task."

    Oh get off it.

    1) The "quote" does not disparage plastic at all, just touts metal as
    their favoured material for high end cameras like the E series.

    2) Oly still use plastic in most of their bodies. And like everyone
    else they have metal bodies for the high end.

    3) I have 4 cameras:
    1 milled aluminum
    1 cast magnesium
    1 mainly cast magnesium with some polycarbonate panels
    1 100% molded polycarb.

    None are damaged despite long non-gentle use. All take great images.

    The whole linked "article" is very typical of the ads camera cos. put
    out to influence buyers as to the "durability/strength" of their
    products. The classic tag line in there was: "Offering a solid feel..."

    Rich: Get a camera and start making photographs. As it will "Offer you
    a solid feel" get a metal one.

  3. I've a load of cameras, plastic and metal.
    All of them are fine.

    As my plastic cameras have survived, what do you think I should do to
    shorten their life??

    Which metal bodies are those? The ONLY DSLR that had one (a great
    one) was the E-1. It left production a year ago.
    Yes, Olympus did go on a cost-cutting binge and it has brought them
    into the black now, thanks to the worthless taste and brains of the
    average buyer, who value 18x zooms and high pixel counts (even though
    the morons will never print beyond 4x6") and portability over qualilty
    of image produced. But only a fool would argue their new cameras are
    even a patch on the older ones, and I'm talking about the P&S
    cameras. The bodies on the current crop of their DSLR are merely
    acceptable for general use and they are all "entry level" at best.
    They have no prosumer and no pro bodies.

    I don't know about their life, but how about the photogs? Do your
    hands ever sweat when handling those cameras?


    CALIFORNIA
    Legislature considers bill to ban chemical from kids' products
    Bisphenol A found in pacifiers, toys and baby bottles

    Jane Kay, Chronicle Environment Writer

    Thursday, March 31, 2005

    An obscure chemical in hard plastic baby bottles, liners inside canned
    food and some water containers lies at the center of controversy as
    the California Legislature considers a bill to ban it in children's
    products.

    If passed, California would be the first state to limit its use.

    Bisphenol A -- the prime chemical in making the polycarbonate plastic
    popular in durable, clear Nalgene water bottles -- has come under
    increasing scrutiny in recent years from scientists who caution that
    it's found in thousands of consumer products and has invaded the human
    body.

    Industry representatives say the chemical in the products remains at
    insignificant concentrations, and they maintain that nationwide tests
    compiled by the Centers for Disease Control and Prevention show that
    the bisphenol A levels in people aren't worrisome. The Food and Drug
    Administration permits its use.

    But researchers have found that at doses below or at a federal safety
    guideline, the chemical can disrupt hormone systems of lab animals,
    affecting the workings of their brains.

    Bisphenol A has been used for decades in the manufacture of tough
    plastics known as polycarbonate plastics. The plastics make up a wide
    variety of products, primarily food and drink packaging and containers
    such as hard, clear and sometimes tinted Nalgene water bottles, and in
    toys, pacifiers, baby bottles and teethers.

    The chemical is also used in epoxy resins that coat food cans, bottle
    tops and water supply pipes, and as sealants for children's teeth for
    the prevention of cavities.

    Assemblywoman Wilma Chan, D-Oakland, became aware of the chemical's
    possible hazards through her work on the Select Committee on
    Children's Health and School Readiness and introduced a bill last
    month that would prohibit the manufacture or sale of any product
    intended for use by a child 3 years of age or younger, if it contains
    bisphenol A.

    The bill, AB319, also would ban in toys and child care articles
    certain forms of phthalates, plastic softeners.

    The committee, which she heads, has turned up a number of studies
    showing that bisphenol A and some phthalates can cause hormone and
    nerve damage in young children, she said.

    Chan, whose legislation led to the banning of two forms of flame
    retardant two years ago, said she was "shocked to find out that there
    were chemicals in toys that babies put in their mouths and in baby
    bottles.''

    "We just shouldn't have these products on the market in California,''
    Chan said.

    According to 1999 industry data, about 2 billion pounds of bisphenol A
    are produced yearly in the United States. In the last 10 years,
    criticism has grown with studies showing that bisphenol A can leach
    from products under high heat and alkaline conditions, and the rate of
    leaching is affected by the age, condition and wear of the products.

    Nalge Nunc International, which makes Nalgene bottles, didn't return
    calls.

    The American Plastics Council, which represents companies that use
    bisphenol A, maintains that the amount of leaching isn't significant.
    The group opposes the Chan bill.

    "The bill is written fairly broadly,'' said spokesman Steve Hentges. A
    ban on bisphenol A could potentially eliminate the coating used to
    line cans to prevent metal from corroding into foods. "You can't make
    polycarbonate without it.''

    At this point, Chan said, her bill doesn't attempt to regulate the
    bisphenol A in food cans.

    As for the health effects, Hentges said, "The evidence has been
    examined by governments and scientific bodies worldwide. In every
    case, the weight of evidence supports the conclusion that bisphenol A
    is not a risk to human health at the extremely low levels to which
    people might be exposed.''

    But an author of one of the new studies, Thomas Zoeller, a thyroid
    endocrinologist and chairman of the University of Massachusetts'
    biology department, said researchers had shown that humans were widely
    exposed to bisphenol A, a chemical that can disrupt animal hormone
    systems that affect the workings of the brain.

    Further, it appears to accumulate at higher concentrations around the
    fetus -- in the umbilical cord and the amniotic fluid -- than in the
    mother's blood, said Zoeller, a leading authority on fetal thyroid
    development. While it's not clear what the affects are on humans,
    Zoeller and his colleagues published a study in the journal
    Endocrinology in February showing that, in lab animals, bisphenol A
    altered the ability of thyroid hormone to correctly regulate brain
    development.

    In another study, expected in an upcoming issue of the journal
    Neuroscience, a University of Tokyo group found that bisphenol A
    inhibited the positive role of estrogen in enhancing neural
    connections in a part of the brain involved in the formation and
    retention of memory, the hippocampus.

    And a study by researchers from Yale University School of Medicine and
    Helen Hayes Hospital, affiliated with Columbia University Medical
    School, also found negative effects on the hippocampus. The study was
    published in February by Environmental Health Perspectives, the
    journal of the National Institute of Environmental Health Sciences.

    Scientists recognize that an increased rate of synapse formation may
    benefit memory, and the hormone estrogen in both the female and male
    brain is important in terms of increasing the density of synapses.

    Yet, when the Yale and Helen Hayes researchers injected extremely low
    doses of bisphenol A in rats, "the positive effect of the estrogen was
    strongly inhibited because there were fewer synapses,'' said Neil J.
    MacLusky, a developmental neuroendocrinologist at the hospital's
    Center for Neural Recovery and Rehabilitation Research.

    "We don't know that it necessarily means anything for human beings,''
    he said. "But if these kinds of biological effects occur in humans, it
    raises serious issues.''

    Do you have ANY evidence to support this outlandish claim that sweat
    can leach BPA plastic and that BPA can be absorbed through the skin?
    And do you have any evidence that shows this exposure is a health
    concern?

    Didn't think so....

    There's a scene in the movie _The Paper_ where someone complains about
    Robert Duvall smoking and says something about 'doctor found nicotine
    in my urine again'. Robert Duvall's response is a classic....

    IOW, don't let children chew on your camera.

    BTW, the California Legislature is STILL considering this bill.

    There's a new soap coming out with caffeine in it. Do you suppose
    things can be absorbed into the skin without having to be ingested
    directly? Like nicotine patches, for e.g.?

    Typical Rander avoidance technique - change the subject whenever
    called to task.

    Caffeinated soap is not new, and it is nothing more than soap with
    caffeine added. And all the caffeine does is give a reason for people
    to pay too much for ... a bar of soap.
    Not like a nicotine patch at all, doofus. You'd know this if you had
    even a smattering of exposure to pharmacokinetics or you resisted the
    urge to just make up stuff hoping it sounds good enough for people to
    believe.

    Nicotine is fat soluble and readily absorbed through the skin.
    Caffeine is water soluble, and it is not readily absorbed through the
    skin.

    Go adjust your tinfoil beanie (remember, the shiny side out). Buy a
    camera and go take some pictures.

    Tell them.


    Wake up, smell the coffee - or is it the soap?

    * Steven Morris
    * The Guardian
    * Friday April 20 2007

    Help may be at hand for the sort of person who is in such a rush that
    they don't have time both to shower and drink a cappuccino - a
    caffeinated bar of soap.

    The manufacturers claim that as a person lathers him or herself with
    the Shower Shock soap it releases caffeine that is absorbed into the
    user's system and provides the same hit as a couple of cups of coffee.

    Happily the soap is also infused with peppermint and citrus scents so
    you don't end up smelling like a jar of coffee beans . A shower gel is
    also on offer, although the makers, Think Geek, warn that neither is
    recommended for pregnant women or children because of the caffeine
    content.

    Jennifer Kuropkat, of Think Geek, said both products were aimed at
    people who just did not have time to get the coffee on and get washed.
    In America, where it was invented, it is being sold under the
    advertising strapline: "Have smelly co-workers that sleep in too much?
    Give them the gift of Shower Shock."

    Ms Kuropkat said: "We love caffeinated products and our designers came
    up with the idea to combine it with a soap. Every full body wash with
    the Shower Shock soap will provide the equivalent of around two cups
    worth of coffee.

    "The caffeine is absorbed through the skin and into the bloodstream.
    It has exactly the same effect as if you were drinking coffee. Your
    blood pressure and pulse rate will increase, making your brain feel
    more alert and awake.

    "The caffeine will then last in your system for approximately four
    hours - the same as two cups of coffee. They really are time-saves as
    you don't have to wait around for your coffee to brew in the morning."

    The 4oz bars of soap, available via the internet, cost £3.50, and
    there is also a smaller travel version. The Mountain Dew shower gel
    costs £6.50.

    [press release for ThinkGeek snipped]

    No matter what the fine folks at ThinkGeek say about their product, it
    is NOT a vehicle for caffeine. And saying so in a press release
    doesn't make it true.

    All of the effects they reported (increased blood pressure and pulse
    rate, feeling alert and awake, etc) can all be attributed to taking a
    shower and oil of peppermint and citrus.

    Go adjust your tinfoil beanie (remember, the shiny side out). Buy a
    camera and go take some pictures. And quit making stuff up.

    You're pretty gullible if you believe this, and are engaging in
    your usual trollish behavior if you don't. Try to work it out,
    based on estimates of the number of washes the 4oz bars should be
    good for, the amount of caffeine that could be added to the soap
    without changing it into a product that doesn't resemble soap, and
    the estimated percent of the caffeine that doesn't get washed down
    the drain, assuming that you aren't so foolish as to believe that
    100% of the caffeine is absorbed into the body. Coffee has about
    80mg of caffeine per cup, btw. My bets are on trollish behavior.

    Forget the coffee, it was a tangent and doesn't matter. As usual, a
    thread can't go two posts without some baby getting their feelings
    hurt because an engineer stated the best material for a camera isn't
    what the little baby's camera happened to be made of. Plastic,
    polycarbonate is a great material for a camera body...except for all
    the other choices.

    There was a mention in yesterday's news about a new bridge design
    that replaces steel with plastic. It was estimated to increase
    bridge longevity by about 50 years. A good part of this is
    supposedly due to the steel deteriorating rapidly when its
    protective concrete coating is breached, exposing it to the
    elements. You probably won't really be happy until transparent
    metals are discovered that can be used for lenses. You do realize
    that glass is plastic, constantly flowing, so that if you leave a
    camera undisturbed long enough, the bottoms of lens elements will be
    thicker than the tops! :)

    Man, oh, man. I sure hope you don't have such a runaway mouth when
    you're speaking to people in person. What a series, "fool," "moron,"
    "worthless taste and brains," and on about people who don't do as you
    think they should do.

    In my old neighborhood, someone would dropkick your ass over a

    It's not that. Rander is getting worn down from all the campaigning,
    each and every day aiming for the top, month after month, Asshole of
    the Week. The wear and tear now has him thinking he's important enough
    to stalk, or to otherwise take seriously.

    So if we accept your assertion that we accept the head engineer at
    Olympus as being credible, what this also must mean is that *all*
    materials that Olympus chooses to put in their cameras have been
    approved by this gentleman.

    In other words, for whatever material selection that Olympus makes in
    its camera product lines, then there's some credible reason why *the
    guy RichA selected as authoritative* chose it as the best engineering
    solution for that product.

    And directly to the point, this means that if Olympus uses any
    plastic, it must be okay by this guy ... who RichA has selected as
    credible!

    So....has Olympus used any plastic in their cameras?

    A....Yup.

    Thus, Olympus's head engineer approved their use.


    And henceforth, let it be known throughout the realm that RichA,
    through the use of a subject matter expert *of his own choosing*, has
    utterly discredited his own anti-plastic arguement.

    Why? Does he determine the engineer specifics for even the cheap
    (made by Sanyo) P&S cameras?
    Also, you missed the term, "best material." As in magnesium is the
    best.
    Acceptable might be polycarbonate.
    Barely usable might be polystyrene.
