Flash Mode Manual, S1, S2: Many photographers like the manual mode in strobist photography, because it gives them most freedom in composing their pictures. You can adjust the power level from 1/128 to 1/1 in 1/3EV steps. Also you can use the optical slave modes S1 and S2. Which allow optical triggering by other flashes without need of an additional trigger. The S2 mode supresses the TTL metering flash.
Multi Mode: In this mode a sequence of rapid flashes is fired and give interessting effects. You can adjust the number and frequency of flashes.
Big LCD with advanced settings: The big back-lit LCD is quite comfortable and for newer Canon cameras all information is also available in the camera menu and can be set there as well. Settings can be saved to a hot key which makes it fast accessible right if you need it. The last settings are automatically saved.
Auto Zoom Head, Wide Angle Diffuser and Bounce Card: The flash head zooms automatically or manually to the focal length transmitted by the camera in steps of 24, 28, 35, 50, 70, 80, 105mm. The zoom range can be extended to 18mm by the diffuser. Also the head can be rotated horizontally and vertically in wide angles.
Wireless TTL Slave: Use the comfort of TTL wirelessly with Canon eTTL and Nikon i-TTL! The YN-565EX serves as a wireless TTL slave which is triggered by a compatible master flash like the Canon 580 EX II or Nikon SB-900, a camera with commander function like Canon 60D or wireless commander like ST-E2. If there is no commander function or master flash it still can be used with TTL on top of a compatible camera.
