    Yongnuo YN-560, version III has even an integrated receiver. Note that Yongnuo's remote transmitter, RF-603, does not have active middle contact, they are compatible only with cameras they are designed for (i.e. modern Canons, Nikons...). Their older transmitter, RF-602, might have it active, I'm not sure this.

    The OP asked for a handheld flash to use with a Mamiya camera. So............ Distance X F/stop = GN. IE: 10' X 11 = 110 This has nothing to do with power into a light box/umbrella or parachute, it's simple and gives a guide not an absolute value.
    Makers use this as a basis of comparison using a reflector that will give an evenly lit area with a standard lens.
    With units that have changeable reflectors the GN on it's packaging may or may not give a GN for each variable
    but you can still determine a GN for yourself.

    FWIW the Vivitar 283 and 285 have the same output. The 283 is slightly smaller & lighter. The 285 has a variable power dial and Zoom head, effectively changing the coverage of the flash.

    The Vivitar 283,285 are shoe mounted flashes, hand held flashguns in my book are hammer head, spud masher type flashguns .

    Sunpak 622 Super Pro. It will fry the fur off an armadillo at 100 yards.

    Seriously very powerful, reasonably rugged, and a variety of heads available.

    Have you considered possibly going "off-the-grid" and trying something completely different like a handheld flashbulb unit? Perhaps a Graflex Graflite using Press 25 bulbs?

    Because of the much longer bulb burn times the quality of the light can be quite different from those instantaneous 1/10,000th of a second electronic bursts. You can get a much more natural looking light because the burst doesn't seemingly freeze the subjects at an almost molecular level.

    They'll also usually buy you the complete and totally fascinated attention of your subjects, which can be quite useful at times.

    Press 25s generally run about 50 cents to a dollar each on the auction site, so it depends on the volume you would use and the effect you might be wiling to pay for. The Graflite units themselves can be had very inexpensively.

    Just a (different) thought...

    Ken

    [Edit: Also worth noting is that flashbulbs are generally far more powerful than the average on-camera electronic flash units even from the glory days of film. Here's an example of an entire aircraft hanger lit up nicely by a single Press 25 bulb in a 5-inch reflector. You can see the shadows behind the spotlight housings in the rafters to get an idea of just how much light was thrown. The aircraft is a B-25G Mitchell medium bomber in ground attack configuration. Sorry for the hotspot on the nose. My bad...]

    Yes, a Sunpak 622 in good condition would be an excellent choice. Make sure the battery either has plenty of life left in it, or be sure that you can repack it.

    And Vivitar had a very nice "L" bracket with a removable handle for them.

    And there were brackets for 35mm and medium format cameras.

    If you are going to use a Vivitar flash bracket you may as well use the real thing, the guide number of a Vivitar 285 is 39 meters 120 feet and has 4 auto apertures, the Metz 45 CL5 guide numberis 45 meters (146 feet) and it has 6 auto apertures and is much more versatile and powerful.
