Transmitters and receivers for sending signals between cameras and flash units have been legion in the last few years, but few of them have combined all of the features that people wanted - now PocketWizard have released their new Plus IV
and it looks as though it redresses the situation.
What it provides:
Radio-frequency command between your camera and your flash out to a long distance.
TTL through-put to a flash mounted on the camera - in other words you can send out a manual signal to outboard units while your TTL flash on camera does the usual measuring and quenching thing.
Control for 4 separate flash groups.
Control for 32 channels.
Note that you get an orange back-lit panel when you press the Mode button. When you are using flash in dimly-lit venues any on-board illumination is a blessing. Rocket Wizard have decades of experience in the field.
Auto sensing for pairing the transmitter and receiver.
Two-stage remote camera triggering. Just like the shutter button on your camera - half and full-press and then turns off to save battery power.
Receiver will accept and fire up to 14.5 FPS.
Runs on 2 x standard AA batteries or you can put external power in through a Mini-USB port on the PocketWizard IV.
And best of all - they have lain the body of the thing down forward instead of making it stick up like their old units. Much easier to move about with the camera if it lies along the top of the lens. Note that they have been wise enough to make the battery door a hinged fair rather than a slide-off cover that would be lost and trampled on.
1/4" screw socket on the bottom and TTL hot shoe on the top. A stand-alone independent outfit.
