    I'm using a Canon Rebel and am new to digital cameras.

    I have a perfectly fine Sunpak Auto 511 flashgun which I used successfully
    with both my Olympus SLR and a number of lenses on my 4x5. Can this
    flashgun be used with my Canon or must I get a gun specifically for this
    camera?

  2. 1: Your Rebel may not like trigger voltages above 6V. To make sure
    you don't damage the camera, measure the voltage between the pins
    of the flash when fully charged /before/ you try putting it in the
    hotshoe - or get a Wein SafeSync thingy or a slave trigger unit.

    2. There is no need for a dedicated flash. Some may argue that you
    need a dedicated flash for E-TTL (which is true) - but I believe
    that auto gives just as reliable flash exposures as Canon's E-TTL
    system.

    I discuss the use of auto flashes on Canon DSLRs at the bottom
    of this webpage: http://folk.uio.no/gisle/photo/flash.html .

    Thank you very much. I went to your web page; it is very helpful and I'll
    have to take the time to study it further.

  5. You got a 401 return code - or was it another error?

    401, I can't explain. There is no access restrictions on that page.
    If you got another error code, the server hiccupped.

    Anyway - it appears to be working now. Plaese try again.

    Your owner's manual should be able to tell you if your camera is
    limited to a certain maximum trigger voltage. My 20D manual does.
