Profoto Releases Firmware Update for Portable B1 Flash System Enabling TTL Metering for Canon 1D X


MARCH 31, 2014

By Dan Havlik

UPDATED: Profoto released new firmware for its battery-powered B1 cordless flash system, allowing TTL metering for the Canon EOS-1D X and then promptly pulled it when problems with the firmware occurred.

After releasing the new firmware for the B1 last night, the company sent the following email around to customers this morning saying there was a bug with the firmware that causes the B1 to "get stuck at full power."

"As some of you might have noted, the firmware upgrade we released on Mar 31 contains a bug that causes the B1 to get stuck at full power," the email read. "The bug only appears when shooting in TTL mode with Canon EOS-1D X, but considering today's announcement, that is more than enough to remove it from our site.

The short, non-technical explanation for the bug is: we were too eager and didn't test the upgrade properly. For that we are sorry.

Rest assure that we're now working hard to fix this problem. Vacations have been cancelled, the coffee is brewing, and we will get back to you as soon as we can with an update.

For the meantime, it is not possible to download the firmware upgrade from the Profoto site.

Those of you who do not shoot with Canon EOS-1D X will not notice this bug, regardless if you've performed the upgrade or not. Everything will work just fine."

According to Profoto, one of the most frequently requested features for the B1 since its launch last year has been TTL for the Canon's flagship DSLR, the 1D X.

The firmware update would have applied to the small Air Remote TTL-C radio transmitter, which attaches to a cameras hotshoe, not the the actual B1 off-camera flash itself.

Look for a review of the Profoto B1 in the April issue of PDN and forthcoming online. We'll keep you posted when the new B1 firmware is fixed.
