The Raven is the best kept secret in the industry.
I bought it and only use it with PocketWizard units for now since it's not yet compatible with Elinchrom and SMDV at this time, but I still get incredible value out of it.
So many awesome features on this transmitter, but my favorite is SpeedCycler. It's able to trigger different zones and alternate between them each time you take a photo. This gives you a way to shoot portraits with multiple lighting setups at the same time, giving you way more different selling opportunities for the same amount of shoot time.
This transmitter is perfect for creative business people. If you are always thinking about how to set yourself appart and be unique, the Raven features will unlock business ideas not possible with anything else on the market.
