The flash is equipped with a built-in diffuser to provide a 16mm lens coverage. A soft box is included for the specially designed flash head to soften light output and to reduce shadows while the integrated fill-in reflector bounce card can be extended even when the soft box has been attached. SELECTOR DIAL AND COLOR LCD DISPLAY: The combination of color LCD display and selector dials enable the user with an extremely convenient way to take full control of the flash and the video light function and has 9 levels of illumination. The i60A has TTL and HSS enabled speed light with various slave options for flexible optical wireless flash combinations. LIGHTWEIGHT & COMPACT: The Nissin i60A Flash is a compact, lightweight, high power wireless flash system that delivers an incredibly high power output of 60 GN or 196 feet. Its flash head rotates horizontally 180 to right and left and tilts up 90. This makes bounce shooting more arbitrary, with more angles that can be used. Nissin i60A has a video light function, which has 9 steps of output level adjustment and supports up to 1/8000 second shutter speeds. NISSIN AIR SYSTEM TRANSMISSION: The Nissin Air System, NAS, is Nissins newly developed 2.4 GHz radio transmission wireless flash system. Compared with the traditional optical wireless transmitters, 2.4 GHz radio transmission is less susceptible to angle and obstacle limitations. Equipped with Nissins ID technology, the IDs give each of the NAS compatible devices a unique identity and can be set to prevent misfiring in the event of signal interference.
