The Nissin Di600 Flash is a shoe-mounted flash unit designed for Nikon cameras with E-TTL / E-TTL II functionality. It features a guide number of 145' at ISO 100 in the 105mm position for providing excellent coverage within a zoom range of 24 to 105mm, or down to 16mm with the built-in wide-angle diffuser. The Di600 supports wireless slave functionality and can still utilize TTL metering. It can be controlled by using a master flash unit in channel 1 and group a. This allows you to be more creative with your lighting design. Additionally, manual control is possible with 6 different levels, from full 1/1 down to 1/32 power in full-stop increments. For utilizing techniques like bounce flash, the Di600 can tilt upward 90° and it features 270° rotation. This allows for simple adjustments for a big improvement in the quality of light you desire. It also has a built-in reflection panel for adding some fill light to your shots.
