B&H has several deals on the Canon Speedlite 600EX II-RT, starting with $100 off a single unit. If you are bundling multiple units, along with accessories, then you can save up to $245 off regular prices. Check out all of the options here at B&H Photo.
The PocketWizard Plus IV is in stock and now shipping. For those not familiar with the new Plus IV, it essentially takes all the functionality of the Plus III and added a top shoe for mounting speedlights.
Additionally, the Plus IV will pass through TTL data when mounted on camera but limits transmission to manual triggering only.
The Plus IV is a transceiver, so each unit can serve in a transmitter or receiver role. It is compatible with most Canon, Nikon and Panasonic cameras. It also works with many Fuji, Olympus and Sony models or manual triggering. It will communicate with the older Plus III models as well for tying together speedlight and studio flash commingled setups.
