With a guide number of 60' at ISO 100 and 200mm, this YN720 Lithium Speedlite from Yongnuo is a portable lighting option for those that do not require TTL functionality. Built into it is a 2.4 GHz wireless transceiver, allowing it to be fired remotely at distances of up to 328' or used as a master to directly control the mode and output of compatible flashes. Additionally, it can also be used as an optical slave for multi-flash setups without radio transmission. The speedlight offers a wide zoom range of 20 to 200mm, and can have its panel configured to reach 14mm if a wider spread is needed.
