Profoto Air Remote TTL-C for B1 Air (Canon E-TTL)
The key to wireless triggering and TTL remote control is Profoto's Air Remote TTL-C transmitter, available for Canon cameras but also for Nikon DSLRS (TTL-N) in 2014. Operating on 2.4GHz bandwidth, the transmitter, really a controller, has 8 frequency channels and with 3 groups per channel and a range of up to 330' for TTL triggering and 1,000' for normal triggering. Each channel has power ratio capability of +/- 2 stops. If you prefer to use manual you have +/- 9 stops power variation. You've also got modeling light, unit shut-down and first or rear curtain control. Both the TTL-C and the B1 500 Air TTL have mini-USB connectors for firmware updates directly from Profoto's website. The Air Remote TTL-C will also trigger non-TTL Air heads and packs from Canon cameras but without the TTL feature.
