Free yourself from cables and optical alignment with the built-in Nissin Air System of the Nissin Di700A Flash, which provides reliable 2.4 GHz TTL triggering from up to 98' away. This system works with Sony cameras with Multi Interface Shoe that feature ADI / P-TTL metering and offers wireless slave capabilities for off-camera flash use when using the optional Air 1 Commander. The Di700A is also a very capable flash with a guide number of 177' at ISO 100 and 200mm as well as a zoom range of 24-200mm, which can be controlled manually through the Commander. A built-in wide-angle panel is available for coverage of lenses down to 16mm on full frame. Bounce flash capabilities come in the form of tilting from -7 to 90° and rotating left & right 180° for a full 360° of coverage. Specific to this model is a color LED control panel that allows users to quickly and easy see and adjust settings. Also, it has support for slow, high-speed, 1st & 2nd curtain sync modes and has a recycle time of 0.1 to 4 seconds. Additionally, it runs on 4 AA batteries and uses the BM-02 quick loading battery magazine. This flash features the newer Sony Multi Interface Shoe and is not directly compatible with the older Sony/Minolta-style Auto-lock Accessory Shoe.
