Features:

• TTL FLASH LEVEL COMPENSATION: The power of the flash can be regulated using the TTL flash level compensation. Whereas the total exposure is controlled by the camera's EV compensation function, the flash can compensate for exposure on the main subject only, with little impact on the exposure of the background scene. The flash power level can be adjusted from -2EV to 2EV in 0.5EV steps.
• 3 SLAVE MODES: i40 can be set to Group A, B or C and controlled wirelessly in TTL and manual modes. Using the 3 slave modes, multiple flashes can be set up to enjoy creative photography in any situation.
• SIMPLE SELECTOR DIAL: The i40 has 2 selector dials, a function dial and a power dial. The small lamp indicates the current settings so that even beginners can quickly get started and the video light function. 9 levels of output can also be achieved by using the dials and the i40 can support up to 1/8000 shutter speeds.
• POWERFUL MINI: The pocket-sized Nissin i40 weighs only 7.2 oz. and is perfect for use as a fill-in flash even on the sunniest of days. Its compact dimensions make the i40 the ideal flash for family outings, indoor and outdoor shoots and perfectly suitable for traveling. The flash head rotates horizontally 180° to right and left and tilts up 90°which is suitable for close up photography. This makes bounce shooting more arbitrary, with more angles that can be used.
• NISSIN AIR SYSTEM TRANSMISSION: The Nissin Air System, NAS, is Nissin's 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 Nissin's ID technology, the ID's give each of the NAS compatible devices a unique identity and can be set to prevent misfiring in the event of signal interference.
