    I have an OLD Sunpak Canon dedicated flash and I want to use it on my 'new' Sony DSC-D770 digicam.

    is this possible?

    the flash has three contacts on the bottom, but the hotshoe on the digicam only has the center contact.

    The Sunpak is a good flash with a guide number of 160.

    If I can't use this, what flash should I purchase? I need a minimum guide number of 120.

    The flash will work, it just won't have any "auto" features. it will probably fire at full blast each time, and it won't communicate with the camera to adjust aperture, etc....

    Guide # divided by distance to subject = f/stop at ISO 100

    Test this though, sometimes it seems to me that somehow the manuacturer's GN is about a stop weak or so.
