Today, we are happy to introduce the first firmware upgrade for the B1 off-camera flash and the AirTTL system, enabling TTL metering with Canon EOS-1D X.
Ever since its release in November last year, the B1 has been able to perform TTL metering with the majority of Canon cameras. But there was one exception – Canon’s flagship – the EOS-1D X. Today, this feature is made available free of charge through an easily installed firmware upgrade.
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 upgrade can be downloaded free of charge at our user portal My Profoto.
The process is as follows:
- Go to www.profoto.com/support.
- Sign in with an existing My Profoto account or create a new one. If you create a new one, you’ll have to click the activation link in the email we send you after creating your account.
- Once you’ve logged in to My Profoto, register your B1 and your Air Remote TTL-C. Having your product registered is also a great help if your product is lost or stolen!
- Once your products are registered, click “Upgrade Product”.
- Choose the Air Remote TTL-C and enter its serial number, which can be found in the remote’s battery compartment. This is necessary to verify that your specific remote is compatible with this particular upgrade.
- The download buttons will be activated as soon as a correct serial number has been provided. When they’re active, click either “Download Upgrade for MAC” or “Download Upgrade for PC”.
- Open the downloaded software and follow the simple instructions.
Anyone can create a My Profoto account and register whatever Profoto products they have. As mentioned before, it can be a great help if a product is lost or stolen. But the only firmware upgrade available at the moment is the one for the AirRemote TTL-C.
We’d also like to remind you that this is the first of many planned upgrades for the B1 off-camera flash and the AirTTL system. We’re currently working on the firmware upgrade for high-speed sync (HSS). We’re also busy developing the new Air Remote TTL-N that will enable TTL metering with Nikon cameras. As promised, both the HSS upgrade and the Air Remote TTL-N will be released in 2014. Stay tuned for more info on that.
Last but not least, if there is any confusion around this, leave a comment below and we’ll do our best to reply.
