    Hello John!
    I did. and I did that too.
    Metz is probably the only choice for a professional flash. Has been
    since I was a child and probably will be long after I'm gone - despite
    what Nikon claim about their speedlites.

    Thank you for your input.

    Gee, so who buys Speedtron and Elinchrom and Bowens and the like?

    Last time I looked Bowens and Elinchrom were studio strobes. Hardly a
    camera mounted flash you can run around a reception with, wouldn't you say?

    No, you set them up to light the room and then put a Pocket Wizard on
    the camera.

    I know John but that's not how event shooters work. I often take 400
    shots in a 4 hour time in company with another shooter intending to do
    the same. What doesn't fit on the camera, isn't going to work in such
    situations.

    Anyway... My Metz (and the former SB900) are very capable at lighting a
    whole 100 feet square room, firing into a fibreglass balloon with
    mirrors inside. Sometimes just bouncing the flash off a white ceiling if
    one is available.

    My complaint is not about how well the said SB900 works - it works
    exceptionally well. My complaint is that it can't keep working for any
    length of time without being cooled and Nikon neglect to mention the
    short duty cycle in their pre-sales blurb.

    When you buy a welder or any devise that generates heat, their
    specifications contain a little clause called "Duty Cycle". This is the
    number of minutes expressed as a percentage number that the devise can
    work in any one hour period.

    Even a cheap welder will have a 30% duty cycle at 60% load. The better
    ones as much as 100% at full load. If Nikon published the duty cycle of
    their speedlites, they would never to sell them to anyone who knows how
    to read specifications.

    Example:

    Ambient temperature = 82.4 ºF
    Flash at iTTL in daylight used for fill. 15 shots @ 3 FPS = use time of
    45 seconds, results in a totally unacceptable duty cycle of less than 2%
    (assuming it was at full power). Even less if it was working at less.

    Really pathetic stuff John. Incidentally, whenever possible I do set up
    lighting in advance. Often it is already installed and I only need to
    measure the temp of it but this is a rare event indeed when I can do that.

  6. It doesn't have to fit on the camera hot shoe. There's plenty of event
    shooters who hold the flash in the other hand, or get an assistant to
    hold it, or fit it to a flash bracket bolted to the camera tripod
    mount.

    Jurgen's post seems to have vanished into the ether.

    I don't understand how taking 400 shots in 4 hour time precludes
    setting up the lighting in advance. I'd think that the more shots you
    need to take and the faster you need to take them the more benefit
    there is to prior preparation.

    Pros that make purchases after reading only sales brochures have
    only themselves to blame. Nikon's speedlights have the necessary
    information spelled out quite clearly in their downloadable manuals,
    so any "pro" that isn't aware of the short duty cycle of camera
    mounted speedlights probably is clueless in many other areas as
    well. Would that include you? Let's revisit your previous posts :
    So the question now becomes "How much better are the duty cycles
    that you can get from Metz's flashes?" According to the manuals,
    Nikon states that the SB-800 and SB-900 should be allowed to cool
    off for at least 10 minutes after 15 rapid full power flashes.
    Metz's manuals for the Mecablitz 58 AF-1 and 48 AF-1 state that
    after rapidly taking 15 "full light output" shots, "make sure to
    wait for at least 10 minutes after 15 flashes. Otherwise, the flash
    unit will be overloaded." So it appears that you're either a
    remarkably ignorant "pro", or just a Metz fanboy internet troll.

    Which brings us to
    and my assessment stands. To see the real idiot you only need to
    look in a mirror. The last guy that KF'd me because he couldn't
    tolerate having his bogus facts corrected was our good friend SMS.
    Having so much in common, the two of you should get along famously.

    As shown above, Nikon *does* publish their speedlight's duty
    cycles, and you obviously don't know how to find and read the
    specifications. That you think Metz's speedlights are superior in
    this regard only shows that you've also never read Metz's
    specifications. For your personal aphorism you are hereby awarded
    the well earned and familiar "Ignorance is bliss."
