Anyone use the Quantum Radio Slave 4i with their Dslr?

I’ve read some good reviews on it, and I'm wondering if you need to purchase the canon module in order for it to function properly.

I can't answer your question on the Radio Slave but I can tell you that I use the Pocket Wizard Plus with my 10D and studio lights as well as my 550EX in Manual mode without problems. Quantum is a reputable company. They make great flashes. I use their Q Flash.

I've used Quantum 4i with my 10D in studio - works like a charm. Of course you don't get the wireless-TTL that you get with multiple 550EX's.

The newer Quantum FreeWire slaves require a module to work as TTL, but they don't work with digital cameras because of the pre-flash which is necessary with digi-cams.

All in all, 4i's are a great thing if you shoot in a studio or if your relationship changes with respect to lights.

If you are shooting in the studio (or intend to in the near future) get a Pocket Wizard transmitter and buy power packs with built-in receivers. Less cords, less bateries, less head aches.
