Tom, The creative flash system sells for just about what it did when new even now, but it is multi-dedicated. There is a switch on the main, shoe-mounted unit for Ca (Canon), Ni (Nikon), Me (Minolta & it also works on most R's as well), Ol, (Olympus), Px, (Pentax) and std for plain hot shoes. All the dedication does is sets the proper flash sync speed for each manufacturer's camera bodies. If you have an R8~9, even TTL, SCA351 flashes won't even set the shutter speeds on the bodies, but they will show the proper flash charged indicator. When I had my R8, I used the pre-flash function on the body and set the aperture and shutter speed by the viewfinder bar-graph to zero it in. It's a pain but what else is there? Or so I thought. The twin-head Hasselblad macro-flash made by Metz will hook-up to the SCA351 module and maybe, with the proper SCA300-to-3000 series adapter cable, it may be able to utilize the SCA 3501~3502 Modules?????? Has anyone tried this yet?? I'm stretching the envelope here guy's. A friend of mine loaned me his Hassy, Macro-flash and it worked perfectly with an R5, R6.2 & an R7 that I had. I found out that this flash has a combined guide number of somewhere in the neighborhood of 98 or so (ISO) and that's pretty overpowering! you may need to use ND-4 gel filters on the heads for close-up work, that's what I finally did and at about 8" & f/11, it worked out pretty much right on. Hope this helps.
