Create your own unique lighting effects by triggering remote flash heads with the Profoto Air Remote TTL-O. This flash remote allows you to connect the Olympus OM-D E-M1 or OM-D E-M5 Mark II camera as well as a variety of AirTTL and Air flash heads. The remote uses a 2.4 GHz radio-transmission system that supports up to 8 channels and 3 groups. In normal mode, the remote synchronizes the flash at 1/250th of a second. However, it extends the synchronization down to 1/8000th of a second as you shift the remote to the high-speed sync mode. The remote has an operating range of 300 m for non-TTL and 100 m for TTL flash heads. With the mini-USB port, you may update the firmware of the flash remote. The remote can stay operational for 30 hours on two fully charged AAA batteries.
