    Me too.

    I 'm sure the grip fits the M645. My father had a friend who liked the Mamiya left hand grip so much that he drilled a couple of holes in the base of his Hasselblad to make it fit! I think I would have removed the pins from the grip instead.

I doubt it would hurt the SB600 in manual mode, but we can flip a coin to see which of us tries it first and maybe fries his camera.
    You should get 1/60 flash sync just by putting the SB600 on the hot shoe and using the focal plane shutter as normal. I doubt there is any danger to the camera, since the X-Sync is likely to be a simple mechanical switch, and in any case the SB-600 uses a low voltage trigger. However since your PRO is already on the way, I nominate you to try it first - I still have to get mine!

    I was particularly interested in syncing with the leaf shutter lenses since they can sync up to 1/500, which is a great benefit when the ambient lighting is strong. I already struggle to get daytime fill and reasonably shallow depth of field with the 1/200 sync of my Nikon, so won't even try outdoors at 1/60"!

    Yes there are leaf shutter varients of many of the 645 lenses, plus the 70mm which AFAIK is only available in the leaf shutter varient. This is why I'll need the sync cable, to connect the X-SYNC of the lens to the flash since the camera hotshoe only connects to the focal plane shutter's X-SYNC.

    Good point. Interestingly, the early prism finders for the original 645 and 645 1000s have hot shoes on top of the finder for use in landscape orientation, but this apparently useful feature was dropped for the Super and Pro. I'll look into a flash bracket as others suggest if I find this a problem.

    Thanks to all for your help.

    I use a variety of different flashes with my Mamiya 645 Pro. I have a leaf shutter lens, and I have used it with some of those flashes.

    The hot shoe on the side of the camera isn't really suitable for mounting the flash. The geometry would result in a flash putting too much strain on the shoe, unless you used the camera turned sideways at all times. The shoe is actually designed for connecting something like a corded connection for an off camera flash.

    There is a grip that works with the 645 Pro, and it is not the grip that works with the RB-67/C330. That grip's trigger actuator won't connect physically with the camera's shutter release - the geometry is close, but not quite.

    The correct grip is the one pictured below. It has an electronic shutter release and a working hot shoe, as long as it is used with the correct connector (the connector for the Pro is different than the one for the Super). The hot shoe will only help you though if you are using the focal plane shutter. If you want to use the leaf shutter, you need to use a pc to hot shoe adapter mounted on the grip (the SB600 doesn't appear to have a pc cord option).

    If you want a rotating flash, you could try a grip like the one pictured here:

    Hope this helps.

    I think the RB67/C330 grip will fit but possibly, as you suggest, the shutter linkage will not line up.

    There is an M645 in my father's collection and I'm fairly sure he had the same grip on it as I have on my RB67. I will have a look at the weekend.

    If you're going to want a flash bracket for a 645 Pro or Super get one that does it right....

    I bought one of these on the 'bay a few years ago for about the same money and use it with either a Vivitar 283 or Sunpak 383.

    Steve:

    I just tried my RB-67 grip (again) on my 645 Pro. When fastened, the shutter linkage is pushed fully into the shutter release - the button on the camera is permanently pushed in.

    On the RB-67 and C330 the shutter release is mechanical, and has a fairly long throw. On the 645 Super and 645 Pro bodies, the shutter release is electronic, and has a fairly short throw.

    To add complexity to the question, there was also a left hand trigger grip for the older M645 bodies (the ones that did not permit multiple film backs). IIRC, those bodies have a shutter release that is similar to the RB-67 - mechanical, with a fairly long throw. Those grips had a mechanical shutter linkage as well. They were/are similar to the RB-67 grip, just smaller. At one time I had one of those grips as well as my 645 Pro and two different 645 Super bodies. One of those 645 Super bodies must have been modified at some time during its life, because the old style M645 left hand trigger grip could be used with it. The other 645 Super body (and my 645 Pro body) couldn't be used with that grip, because of the position and operation of the shutter release "button".

    I don't know whether the RB-67 grips can be used with the older M645 bodies.

    Yes, My SB-600 works with my M645.
