Just wondering if anyone has tried this with any success or had certain settings they used. When I got my D200 the salesperson told me I could still use my 430 but with about 4 stops over exp. Basically useless but possible in a pinch I suppose if you didn't have a Nikon unit. The Canon unit is missing a couple contact points though. I did try it for about 3-5 exposures with various settings and varying results. If there would be potential problems would it be with over voltage damaging the flash?
