    Vivitar flash on Mamiya 645 Pro?

    I've recently acquired a Mamiya 645 Pro (non TL) and wanted to know if I could use a Vivitar 283 flash head on it. I've heard conflicting reports that say some older flash units (this one is from the 70's) put out higher voltage and can fry the circuits on some newer camera bodies. I don't have the manual on this flash so I was wondering if the two are compatable or if anyone has had any experience with this. Thanks

    Daniel,

    I have been using a vivitar 273 for many years now on all of my 645s with no problems.

    I use a Vivitar on my Mamiya 645, no problems to report.

    Thanks Dave. From what I gather the problems mostly result from using old flash units on modern/highly automated 35mm SLR's but I wasn't sure. I also heard that the newer versions of Vivitar 283's use less voltage and are OK but the ancient ones can be a problem so I wasn't sure.

    Congratulations on your new camera. I, too, use a Pro TL and really, really like it. Unfortunately I can't advise on flash as I shoot modern Metz flash.

    Thanks Robert. I really like this camera and I also use a 645 Super that conked out on me but with a CLA its as good as new and with a backup body I figure I'm prepared for anything! lol

    I had a 645 Super that I used my 283 on quite often. I have also used the 283 on a Pentax *isd D**** camera with no problems. I do have the newer Korean made 283.

    I also read the reports about the older 283 putting out high voltages and even in some cases damaging the pc socket contacts. However I've used it on several TLRs, a Hasselblad and an old Olympus with no ill effects.

    CAUTION

    The high voltage units work fine on older cameras - it is the newer ones that are vulnerable. The more electronics, the more vulnerable.

    Mamiya advises caution - I have been specifically warned that my old Metz 202 is likely to damage my 645 Super or 645 Pro. The leaf shutters on my C330, however, are fine with the 202. The answer with respect to my Metz 60CT1 or 2 is, maybe.

    A couple of years ago I was speaking with a camera technician who advised that one of the most common repair requests they get now is to fix either digital or small modern 35mm cameras with either a pc socket or hotshoe, that have been "fried" by using an older flash.

    The damage can either be instantaneous, or cumulative.

    Here is a link to a site that lists trigger voltages for a large number of flashes, and related recommendations:

    Please note that I haven't independently verified any of this.
