Profoto Updates B1 Firmware for Canon 1Dx Users


Profoto today released its long-awaited firmware update allowing TTL metering for its B1 flash with the Canon 1Dx.

The B1 was announced a few months back as a professional wireless battery-powered monolight with TTL capabilities, the first ever. If used together with the Air Remote TTL-C, the B1 works just like any TTL-capable flash system, but offers the output of a monolight instead of a small speedlight. The Air Remote is currently only available for Canon.

Previously, the remote didn’t work with the 1Dx, a curious oversight, since the B1 is aimed at the same professional photographers as the 1Dx. That’s now fixed.

The firmware updates the remote, not the B1 unit. It can be downloaded here.

The company also said it will offer a firmware update for high-speed sync and a Nikon compatible remote later this year.

I’ve been curious about the B1 since its launch, but Profoto has been slow providing a review sample. So, I just bought one unit with a remote.

In the coming weeks I will use it alongside my Canon flash and my Elinchrom Ranger RX, mostly to see how they compare in practicality and usability. After that, either the RX or the B1 will move to new pastures.
