I'd like to know if it is possible to have the Nex-7 perform the motion blur flash trick of the CLE described here, on the Cameraquest site:
"For example, I used to shoot controlled blur-plus-flash action shots, fully automatically, via the following trick:
I'd set up my two 360PX units, joined by an "extra-long" Cable CD I had made by cutting off the ends of the Minolta cable and splicing in about 20 feet of four-conductor telephone cord. One of the units would go on a light stand, the other on the camera.
First, though, I'd prepare the camera by putting a strip of masking tape in the flash shoe, so it covered the sync (center) and flash-ready (left) terminals, but NOT the TTL (right) terminal.
Then I'd dim the room lights and tell the model (usually a ballet dancer) to start moving. With the flash-ready terminal taped over, the CLE's auto exposure system would set a long shutter speed appropriate for the ambient light. I'd watch the action through the viewfinder during exposure (impossible on an SLR, of course!)
When I saw exactly the peak action I wanted, I'd press the "test" button on the camera-mounted flash. Both flash units would fire; the TTL system would control them for correct flash exposure; and the sudden burst of light would terminate the ambient-light exposure immediately afterward!
The result would be a long, liquid-looking blur terminated by a sharp flash image of the exact pose I had chosen. Slick, huh? No, you can't do this with "second-curtain sync" because you don't have exact control over WHEN the flash exposure is made. But with the CLE, it was a cinch!"
I'd like to do the same trick but use a radio trigger if possible; I've been playing with the hotshoe adapter and the cowboy studio triggers to good effect but haven't been able to do what is described above.
