The Metz mecablitz 58 AF-2 TTL Shoe Mount Flash for Canon DSLR is the premier Metz shoe mount flash designed to be compatible with digital Canon SLR cameras. To better facilitate compatibility with cameras, this flash features a built-in USB port that allows for future firmware updates via the Internet. Advanced features include a secondary reflector with 3 light output ratios, built-in reflector card for soft light, a metal base for easy attachment, and a constant modeling light for pre-visualizing the flash.

The 58 AF-2 has evaluative pre-flash and is designed to fully support a Canon digital SLR camera's TTL system.  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. If the camera has a built-in flash, the mecablitz 58 AF-2 can also be employed wirelessly in the system, even in servo mode.
