The Leica SF 58 is a shoe mount flash that revels in its versatility. For starters, the SF 58 is compatible with the TTL metering systems in select Leica-R SLR cameras, Leica-M rangefinders, and the Leica-S medium format digital cameras.
Furthermore, this flash's performance range extends to its light output as well. The head both bounces and swivels with a powerful guide number of 58. An automatic/manual zoom head that goes from 24-105mm with the option to use a diffuser that spreads the light to accompany lenses as wide as 16mm with an accessory diffuser (14489 - not included) and 18mm with the built-in one.
The most intriguing ability the SF 58 possesses is two separate light outputs that can be mixed and matched for illuminating effects. The main reflector has 25 selectable output levels and the secondary one has 3. Preset profiles include a mode for standard and one for soft light.
