That's right. With some third party flashes the D70 will even sync at all shutter speeds down to 1/8000. (I've seen this in practice with a Metz flash). Me too (with a tiny and ancient Starblitz). But it does require a Don't-try-this-at-home warning that the manual warns that "Negative voltages or voltages over 250 volts applied to the accessory shoe could not only prevent normal operation, but damage the sync circuitry of the camera or the flash" I assume any single pin flash unit (plus some with extra pins which manage to avoid sending or receiving the wrong signals to or from the camera) would be able to perform this trick, but you have to know that the flash won't exceed that 250v limit, or at least have protection against excessive voltage. Also, I noticed underexposure (just perceptible at 1/4000, pronounced (about 1/2 to 2/3 of a stop) at 1/8000), presumably because the electronic shutter closed before the flash had finished firing, and that may be one of the reasons why Nikon don't allow their own flashes to exceed the 1/500 speed limit. -- Apteryx Treat anger like gold.

Not 100% sure on the D70, but I was told by someone in Olympus's training
section that the E-1 can synch at any speed - it does this by telling the flashgun what shutter speed is in use. If the shutter is fasterfaster than the normal synch speed (ie, speeds where the 2nd curtain starts closing before the first curtain has finished opening) the flashgun holds it's flash on for the entire duration of the shutter. Presumably this function only works with Olympus flashguns, and i'm not sure what the conventional synch speed is with the E1. I wonder if the D70 is doing something similar?? "Alan Browne" wrote in message . .. http://www.dpreview.com/reviews/nikond70/page2.asp According to the link above the sync speed of the D70 is 1/500. Can anyone confirm this? If so I would guess since the curtain travel is a bit shorter that they could shorten the time... but 1/500 is a real improvoment for this class of SLR... or any SLR (not counting leaf shuttered SLR lenses). The only other SLR's at near this speed are the F5 and Maxxum 9 (both at 1/300). Is it limited to the built in flash ... does it apply to attached speedlights?

No Alan, it's not HSS. The flashlights mentioned certainly do not support HSS. This is real thing. Of course, you need some experimentation and adjustments to get correct exposures at faster shutter speeds, but this is quickly done with a digital SLR.
