The Nissin i400 TTL Flash for Sony cameras is a simple but powerful compact flash designed for use by both pros and enthusiasts. It features ADI / P-TTL functionality and a guide number of 131' at ISO 100 and in the 105mm position for providing coverage within a zoom range of 24 to 105mm, or down to 16mm with the built-in wide-angle diffuser.

The shoe-mounted flash head tilts upwards 90° and rotates 180° in both directions for complete 360° coverage. The i400 features full manual control as well as a range of preset modes to achieve just the right lighting setup. Choose from slow-speed, high-speed, and 1st and 2nd curtain synchronization in addition to variable power from 1/1 to 1/256. The flash runs on 4 AA batteries. This unit is compatible with Sony's Multi Interface Shoe and is not natively compatible with the older Sony/Minolta Auto-Lock Accessory Shoe. Though, with the use of ADP-AMA Shoe Adapter, Sony cameras with the Auto-Lock Accessory Shoe can be adapted to use Multi Interface Shoe external flashes with full compatibility.
