interesting... that is fast enough for some of my shots, and it means I can do them in daylight!
but on the page it specifies that is the FLASH speed is 1/60,000, and the shutter is around 1/10,000... than means it is NOT fast enough for some of the ones I plan to attempt... but can that takes sequential shots?
That is interesting, maybe it's time to shop for a cheap used canon to hack.
Another effect I like though is to fire the flash several times to get a multi-effect IIRC, The Nikon F4 could do this with a control back, and I know the F801 could.
