The Metz mecablitz 50 AF-1 TTL Shoe Mount Flash for Canon DSLR is a Metz shoe mount flash designed to be compatible with all digital Canon SLR cameras, both current and future models. To better facilitate compatibility with current and future cameras, this flash now features a built-in USB port that allows for future firmware updates via the internet. A high quality metal base allows quick and easy attachment to the camera.
The 50 AF-1 is designed to fully support a Canon digital SLR camera's TTL system. Both E-TTL/E-TTL-II flash mode and E-TTL remote mode (slave and servo mode) are possible. It can be operated as a TTL slave unit that can be controlled by the camera's own built-in commander mode or as a manufacturer's flash with master capabilities.
The flash also features an auto zoom head from 24-105mm that can be set to match the camera's sensor, a full bounce and swivel head (with a fully swiveling reflector system which also contains a flip-out reflector card and a diffuser), a built-in wide angle diffuser for 12mm coverage, and in addition, full manual control with 12 variable power output levels.
