Last weekend I had a modest fashion-shoot and while I normally work 100% with the mamiya and film, this time I only used it at the very end, just to make some pictures of the models who were friends. The lighting was balanced with an umbrella and available light, resulting in a shutterspeed of 1/4th to 1/8th of a second. I was using Pocket Wizards to trigger the flash, and since the hot shoe on the camera body doesn't work, I connected the Pocket Wizard to the lens X-sync connection. Now what happened was that there were 2 flashes, one on the opening of the shutter (normal) and just on closing as well. It's this 2nd flash that had me wondering. It's like a 2nd curtain thing. It's on the negatives, so they're slightly overexposed (flash was just used for fill, so the power was very low), and when the models weren't standing perfectly still, there are double images, so I know the film 'saw' the second flash. My question now is: could someone verify for me if this is also the case when using the hotshoe? (note: same effect when I connect the flash (nikon SB28) directly to the lens). If it's not, I'll get the hot shoe fixed, it's quite annoying.
