Profoto releases the first firmware upgrade for the B1 off-camera flash and the AirTTL system, enabling TTL metering with Canon EOS-1D X.
When launched in November 2013, the Profoto B1 off-camera flash caused such a buzz in the photographic community that the company’s website crashed. The B1 was the world’s first cordless monolight with TTL. The words “game changer” have appeared in reviews and forums ever since.
The TTL metering is made possible with Profoto’s patent-pending AirTTL system. Already at launch Profoto promised to continuously update the AirTTL system. One of the most frequently requested features is TTL metering with Canon’s flagship model: the Canon EOS-1D X. Today, this feature is made available free of charge through an easily installed firmware upgrade. But note that it is not the B1 off-camera flash itself that needs to be upgraded; it is the small radio transmitter that is mounted on the Canon camera’s hot shoe: the Air Remote TTL-C.
The process is very simple:
1) Go to www.profoto.com/support
2) Sign in with an existing My Profoto account or create a new one
3) Register your B1 and Air Remote TTL-C
4) Download the upgrade
5) Open the software and follow the simple instructions.
