Product Description
The new Nissin Di700A with Commander Air1 is a 2.4GHz radio transmission wireless flash system that links up to 21 Nissin Air System Flash guns. Radio transmission is more flexible than optical systems as it doesn't rely on line of sight and is less susceptible to angle and obstacle limitation, plus coverage of the new Nissin Air System is up to 30m. Transmission Channels and radio transmission IDs can be set to prevent misfiring in the event of signal interference on the same channel. The Nissin Commander Air1 can control 3 groups of new Nissin Di700A flash (maximum 21 guns).
