Yes, the new Pocketwizard Flex (transceiver) units and Mini (transmitter) units work with E-TTL. Yes, you can do high-speed sync with them. Pocketwizards also developed a technology called Hypersync that allows another stop or so pastthe naturalmax sync speed of your camera using (I believe) any flash. The units are re-programmable using a USBcable and your computer.

This is exactly the shortfall I was talking about because of therushed the R&D and testing before releasing the units. The performance, I've heard, using a 580EX flash is abismal. There are steps you can take to improve the situation, but they are inconvenient and somewhat costly (at least compared to everything working great out of the box). The biggest reason to pay the premium price for Pocketwizards has always been range and reliability. With the new units, the range and reliability of the units have clearly suffered (using the 580EX units, at least) and thus have stained the Pocketwizard's great reputation.


As far as what you should buy--I suggest you do as much reasearch on the new Pocketwizard units as well as the Radiopopper PX units if you absolutely must have E-TTL capable, off-camera, radio-triggeredflashes. Otherwise, if youthink you can live without E-TTL, then read up on Cybersyncs, Radiopopper JrX, and CTR-301p (decent ebay) units. Personally, I use Cybersyncs after having had ebay units for quite some time. I enjoy the reliability and range of the Cybersyncs, and I don't mind adjusting the power of my flashes manually.
