The Phottix Mitros+ TTL Transceiver Flash features a built-in Odin transmitter and receiver with full ADI / P-TTL functionality for use with Sony Multi-Interface Shoe cameras. With a guide number of 190 at ISO 100 in the 105mm position, it is capable of lighting subjects within a zoom range of 24 to 105mm. Rotate the flash head 180° in each direction and tilt from -7° to +90° for full control over bounce. Radio transmission is compatible with Odin and Strato II wireless triggering systems in 4 channels and 3 groups with a range of up to 100m. Memory functions make it possible to save up to three sets of flash and function information for convenience. Recycling time is a fast 0.1 to 5 seconds that can be kept to just 2.5 seconds with a quick flash mode. An AF-assist light makes it possible to work in poor lighting conditions and a modeling flash setting makes it possible to preview how your shot will turn out. The Mitros+ also includes full manual controls and customizable shooting options that include high-speed sync and stroboscopic shooting modes. The flash runs on 4 AA batteries and comes with an attachable diffuser for softening light when needed. Other accessories include a soft case, 3.5mm sync cable, USB cable, USB drive with manual and a flash stand. A bounce card and wide-angle diffuser are built into the flash head. This model comes equipped with the Sony Multi-Interfrace Shoe and is not compatible with the older Sony/Minolta shoe.
