Vivek, you might
find this to be of interest. Sync up to 1/4000
The problem with this (if you read the whole thread) is the need to use very specific speed-lights , transmitters, and accessories. The speed-light required is pretty huge on these small cameras if used for fill, and won't hyper sync when used that way ... or if used off-camera with hyper-sync, they are still speed-lights which are incredibly limiting compared to off-camera strobes ... even smaller ones like the EL Quadra.
The sample the guy uses is quite nice, and the photographer knows lighting. However, it is a deceptive example ... a very contained situation with aux light used in a very small area on the subject, and the lighting was probably very close to the subject just out of frame camera right. Good for that specific creative situation, but perhaps not many more demanding ones. Speed-lights simply suffer from a crippling level of output when any distance is added to the equation. Even a lowly Quadra is 4 to 5 times the output of the most powerful speed-light.
I'd hazard a guess, that will not be a limitation of the VX since it is a Leaf Shutter lens just the same as those used in MF lenses like Hasselblad H lenses, Phase One LS, Leica CS, which sync to 1/800, 1/1000, or more. In the case of the VX more likely to 1/2000 using
ANY speed-light on camera for fill, or any strobe system, with no gerry-rigging, or hunt for rare parts.
Try lighting
this at such a distance with a speed-light ... trust me, it's not gonna happen:

Get closer, and yeah, a speed-light can work ... like this using a SF58 on an S2 using a HC 100/2.2 @ 1/500 sync rather than the S2s focal plane shutter sync of 1/125 (which would have been 2 stops brighter and blown out the background that was lit by direct sun). It just depends on how bright the background you are trying to expose correctly actually is.

In essence, it appears that the VX can be used with aux lighting the same way as the big Leaf Shutter kits. What fun :thumbs:
