  1. The OP is a regular for making anti-Canon, pro-Sigma posts. Pay
    attention.

    I know it's hot there this time of year, but I don't think it's quite
    *that* hot. And Queensland is a big place, what part are you
    traveling to? What's the nearest post office from the cities on this
    page?

    For general Australia summer temps:

    In January, average maximum temperatures exceed 35 degrees C over a
    vast area of the interior and exceed 40 degrees C over appreciable
    areas of the north-west. The consistently hottest part of Australia in
    terms of summer maxima is around Marble Bar in Western Australia (150
    km south-east of Port Hedland) where the average is 41 degrees C and
    daily maxima during summer may exceed 40 degrees C consecutively for
    several weeks at a time.

    For fellow 'murkins on this newsgroup:

    45 Celsius = 113 degrees Fahrenheit
    41 Celsius = 105.8 degrees Fahrenheit

    I worked in Port Headland during the 80's. It is bloody hot and cyclone
    prone. 150k east is in the desert country.
    You wouldn't really want to go to marble bar in the summer or the winter
    unless you had business there.

    "May exceed" is an understatement in the extreme. It was 43 C in suburban
    Brisbane (85% humidity) and 41C in suburban Perth this week! Armchair
    travelling is a great past time. Unfortunately the sort of information you
    have quoted is what is responsible for people perishing in this country.

    Warning signs all over 3000 Klm road linking Western Australia to the rest
    of the continent tell you it is unsafe to travel during summer months
    without large quantities of water. Hardly a year passes without reports of
    British or Japanese tourists being found perished for lack of water. You
    can't just wander off here with a bottle of vittal in your pack and hope to
    survive!

    Randall, are you just trolling or what?

    Get your facts straight for a change.

    We shot an outdoor wedding in Sept. in nearly 100F heat with about 70%
    humidity and no problems, with our 20Ds. I'm inclined to think Doug's
    problems, or at least his camera's problems, have their source somewhere
    else. But one thing occurs to me, the flashes we were using were Quantums,
    mounted on frames, so the heat from their capacitors was well removed from
    the camera.

    Thanks for that last, converting temps from F to C has always defeated me.
    Other metric things, I'm comfortable with, but for some reason the Celsius
    scale has never clicked.

    No, he said, despite it's other quirks, or words to that effect, it's
    reliable.

    That's not the same as "The daytime temperatures are over 45C every
    day this time of the year" as you said 2 posts ago. Note that you
    used "over" and "every day". If you had said "it can get up to 45C
    out there this time of the year" I wouldn't have questioned your
    statement - but that wasn't what you said.

    Perhaps so, but he's working in heat a good bit higher than 100F
    though. It's a lot to ask of a consumer grade camera.

  11. I am not in the habit of carrying around the official armchair
    traveller's mini weather station when I have to hike 35 or so Klm up a
    remote coast with 60 Kilos of camera gear and food on my back in 45C
    heat ...so my quote of temprature are "best guess estimations". What
    precisely does your fixation with temratures in remote regions of
    Australia have to do with DSLR photography?

    F = C * 9/5 + 32
    C = (F - 32) * 5/9

    How simple can it get? For a common range of temperatures just remember that
    Celsius is about half of Farenheit when you remove the 32F bias.

    Cheers,
    Alan.

    Neat! Works for length and mass too! eg: "22 m in feet", "72 Kg in lbs" prob
    others too... (I have a PC tool called Penta Calc).

    Also suggest bookmarking the mother of all definition pages:
    http://www.unc.edu/~rowlett/units/ which not only has the units but a lot of
    fascinationg history and cultural info linked to the units, variations of the
    units, etc.

    Cheers,

    A bit off topic, but count yourself lucky your dealer would honour the
    warranty, mine passed me straight onto Canon and they refused it blaming
    me for misused. Will not buy another Canon product.

    That is why you buy an extended warranty. Most stores and more and more
    manufacturers are turning to crap.

    For those interested... The camera has fired off nearly 5,000 frames since
    the last lockup. It has been running on only the internal battery without
    the grip and it has discharged to below 30% on several days. The internal
    flash was used all day today when the camera was used hand held while
    following Santa around. Temprature = 28C with 78% humidity. We shot 400
    frames with about 300 using the internal flash.

    Yep, battery life sucks with the flash and yep, the camera got bloody hot
    but never missed a beat or looked like locking up. All I can say is that the
    grip must have been the cause of the problems. Maybe a fault in it's circuit
    (hopefully) so it will be going back next year along with the camera for a
    check out.

    We got some images from another Photographer for enlarging a few days ago.
    Nikon D100 stuff. I've been able to blow up 10D and 20D high res jpgs up to
    400 ISO and get some nice 20"x30" prints so naturally I said "yes we can do
    them". Well what an eye opener that was. I have never seen high ISO files
    from a Nikon before so I was really shocked to see the amount of noise in
    the shadows. Has anyone else seen this sort of thing? I find it hard to
    believe that a Nikon has a noise problem as bad as this.

  19. I use only the internal camera battery, keep two others charged and in
    reach, and seldom have to go to the first one. I have a 550 EX, and
    either I suck real bad at flash, or something's wrong with the camera or
    flash, or the Lumiquest tiny soft box is screwing things up. But the
    flash uses AA batteries, just fine. I use manual when I can set up and
    check, but I am not confident using it when roaming, so I switch to all
    auto, with frequently underexposed shots. They look fine on the preview,
    so I need to check in other ways.

    Glad you are having success again with the 20D, but really, the internal
    flash is, IMO, just for emergencies. Shooting seq. with the internal in
    high heat is abuse. Plus, like any internal, it's too close to the plane
    of the target.

    .. I have a 550 EX, and

    Set the camera or the flash to give about 2/3 stop overexposure on TTL auto.
    You will get much better results with any of the Canon D series this way.
    DO NOT trust the LCD as your exposure guide. It is simply not going to be
    right.
    Use the histogram to see your range of the exposure.
    Remember, you can change the LCD brightness quite a bit, so it does NOT
    represent the true picture.
