If this hasn't been covered already, I thought I'd share. I'll be trying it out very soon. :)

And hi all! Long time no see. I'll be back though...

great little video... i can't wait to try it out though i only have sb-600's and use cls which i dont' think will work for me... also as a note it seems that most for most nikons the shutter goes the other direction ie. top to bottom...

i'll experiment around with my cls setup tomorrow and let you all know if i can get it to work or not...

Saves you from having to shoot upside down, eh? Looking forward to your experiments.

@stereoblind ... lol yeah... it would... and unfortunately no i didn't work via my CLS... my d80 syncs at 1/200 and even at 1/250 there was almost no flash power... i think it's just as i have heard before that the strobe is just trying to do short bursts instead of normal flashing...

so i guess i'm stuck at 1/200 :(

You can also use the focal plane shutter mode "FP" on the 580 EX II and the Sigma Super flash to synchronize at very high shutter speeds such as 1/2000 of a second to be able to shoot wide open with a smaller depth of field. DSLR cameras use focal plane shutters because they can be behind the lens to facilitate less expensive removable lenses.

You can also use a point and shoot camera such as the Canon G9 which has a RAW capability. This camera has a leaf shutter which is in the lens and allows you to sync at high speeds without a special FP mode.

The duration of light is effected by the amount of power that you use. If you use a lower power setting the duration is lower. Strobes are usually specified at t= 0.5. The intensity of the light versus time is shaped like a playground slide. There is a significant amount of light at the bottom of the slide.

Look at some of the high speed photography sites for how to modify one of the Vivitar flash units to sync at higher speeds.
