As your lens has a tripod collar, if you mount that on the bracket, you will have even more room to choose the postion of the flash guns.Rotatable tripod mounting collar provided
Good luck.

Are you sure you are shooting at 1/8000, thats certainly fastgeorgedingwall wrote:Hi Karl,
It is universal Karl, and has quite a large range of adjustment. It is also able to pivot the camera between landscape and portrait orientation without having to re-adjust the flash guns.Carl_Constantine wrote:That bracket also looks pretty universal, should work on any camera/flash system.
I ordered one yesterday, and it arrived at lunchtime today. It works fine with my D200 and pair of SB800s.
The only problem I've found is that I cannot use FP Synch on the camera when the camera is acting as commander for the two SB800s. I don't know if this is how it's supposed to be or if I have not found the setting yet. The work around I've used for now, is to designate one of the guns as the commander and the other as the remote. I then connect the commander flash to the camera using an off-camera SC17 cord.
In order to do this I had to remove one of the hotshoe adapters from the bracket and drill a clearance hole through the bracket so that I could use a tripod screw to attach the commander flash to the bracket.
This now enables me to use the FP synch option and get shutter speeds of upto 1/8000 sec with enough ttl flash power to capture my macro subjects. Who needs vibration reduction when you work at these speeds.
Bye for now.

That is the general case for film cameras (I don't delve into the black arts of digital).Leif wrote:I might be wrong here, but I though the flash sync speed allowed the shutter to remain open while the flash went off. So basically if the ambient light is low enough, only the flash will record, and the effective shutter speed will be ~1/8000", or whetever the flash duration is. However if the ambient light is bright enough to record, then the exposure duration for that will be 1/250" assuming 1/250" flash sync. For macro work we stop the lens down lots, and that helps ensure that the ambient light does not record.
Digital sensor versus film has nothing to do with FP mode. It's all about how the focal plane shutter interacts with the flash.Harold Gough wrote:That is the general case for film cameras (I don't delve into the black arts of digital).Leif wrote:I might be wrong here, but I though the flash sync speed allowed the shutter to remain open while the flash went off.

The real advantage of FP mode is that it allows a picture to be exposed almost entirely by flash lighting even when the ambient lighting is bright enough that it would record at 1/250 (or whatever the minimum sync speed would be). In terms of freezing action, FP is nowhere near as good as the usual single-pulse mode because different parts of the picture are exposed at different times, up to 1/250 second apart.The trick is that in FP mode, the unit does not put out one big flash, but rather a string of very short low power flashes. The string lasts long enough for the shutter curtains to complete their movement, and the pulses come close enough together to produce smooth illumination even when the curtain slit is very narrow to produce a short exposure time at each pixel.
