Profoto is releasing new firmware today for its B1 and B2 flash systems that will enable TTL functionality for Canon’s 5DS and 5DS R cameras, correcting an issue with over-exposure that some shooters using the new Canons were experiencing.
The new firmware also delivers several new features for the B1 and B2 including faster shooting in manual mode for Canon cameras. According to Profoto, the quicker pace will be most noticeable for those shooting with the 1D-X. Thanks to better integration with Canon models, it will also be possible to select TTL or manual mode in the camera menu instead of only on the Air Remote itself.
You’ll also now have the option to deactivate auto power-off, which before turned off both flashes after 60 minutes of inactivity. The Air Remote display will no longer turn black after 30 seconds of inactivity but will instead dim partially after 20 seconds but stay readable for up to 100 seconds before going dark.
The new firmware is required for both the flashes and Air Remotes and is available for download here.
