CLIP & SHOOT
1. Clip it on the camera.
2. Switch it on.
3. Release the shutter button .
The flash fires and its light is automatically controlled by the camera + flash TTL dedicated system.
EVERY OPPORTUNITY
Many photographers think of using a flash only at night or in poor lighting. However, a flash can be very useful in daylight too. Eliminate the shade under trees. Use fill-in lighting to sharpen the subject. Address catchlight in the eyes, and stop motion. Emphasize the lighting contrast. Enjoy more opportunities to use your flash.
FIRMWARE UPDATE
Tired of your flash no longer working whenever a new camera comes onto the market ? A firmware upgrade service is available for the Di622 , which provides a service terminal to upload the latest software. A charge for the firmware update service will apply, varying depending on the area. Please check at your local dealer for details about the update service.

KEY FEATURES
TTL FLASH
Di622 MARK II is compatible with Canon's E-TTL, E-TTLII system, and Nikon's i-TTL system. Those new digital TTL flash systems control the flash light with greater precision and stability.
BOUNCE FLASH
The flash beam covers the frame from 14mm (with a wide angle diffuser built-in) to 70mm of the digital lens.(*) For a longer lens, the flash head reflector position stays at 70mm.
It turns 90 degrees upward and 270 degrees horizontally for bounce lighting.
The flash head also stores a small reflection panel for fill-in shots.
(*) The focal length for the traditional SLR camera is to be multiplied b a factor of 1.5.
WIRELESS REMOTE FLASH 
Di622 Mark II has a wireless remote flash system as a slave unit.
You can enjoy creative flash photography with multiple lightings from the various directions. There are 3 slave modes provided.
Slave Digital (SD): Di622 Mark II synchronizes to the pre-flash system. The master flash is to be set at TTL (E-TTL for Canon and i-TTL for Nikon) mode.
Slave Film (SF): Di622 Mark II synchronizes to the traditional single flash system. The master flash is to be set at manual mode. Studio lighting system synchronizes to this mode. This mode is also available for open flash, and for a standard flash in the market.
Wireless TTL: Di622 Mark II synchronizes to the wireless remote flash system. The master flash is to be set at Channel 1 group A in wireless remote mode.
TTL FLASH LEVEL COMPENSATION
The power of the flash can be controlled with TTL flash level compensation.
Whereas total exposure is controlled by the camera's EV compensation function, the flash can compensate for the exposure on the main subject only, with little impact on the exposure of the background scene.
The flash power level can be adjusted from -1.5EV through +1.5EV by 0.5EV steps.
NISSIN ORIGINAL ?MY TTL? SETTING
The TTL flash power level is pre-set for exposure at factory. You can, however, reset
at the desired exposure level, in +/- 0.75 Ev. by 0.25 Ev increments.
The pre-set value is memorized as your personal standard after switching the unit
The usual TTL flash level compensation works based on this customized level.
X-Contact and External Synchro Contact 
Di622 Mark II can be used without hotshoe cameras. Some cameras provide a flash synchronization contact at X-terminal instead of hotshoe. For this type of cameras, Di622 Mark II has a X-terminal socket for flash synchronization.

HIGH POWER
G.No.62(ISO 200) is obtained at the reflector position for 105mm focal length lens, and 45 at 35mm. (Reference: The guide number of the flash built in the camera is 16 approx. at ISO 200)
POWER ZOOM
The light distribution angle is automatically adjusted for the lens focal length. A high quality stepping motor sharply traces the lens movement with the same speed as that of the camera manufacturer's original flash model.
ENERGY SAVING SYSTEM
The Di622 MARK II has a dual energy saving system.
It automatically enters sleep mode when it's not in use for 5 min., and is reset with a touch of the shutter button or any button of the flash.
If the unit is not in use for 30 minutes, it will automatically power off.
With the flash unit set for slave mode, sleep mode is cancelled and the unit will not automatically turn off until 60 minutes have elapsed.
VARIABLE POWER
When selecting manual power operation, choose from one of the six variable powers for the best lighting effect.
The power level is provided from full power (G.No.62) down to 1/32nd power in 1.0Ev increments.
AF ASSIST BEAM
In darkness or dim light conditions, the Di622 MARK II beams a red light to create a sharp contrast to enable the camera's focus sensor to focus easily on the subject.
FLASH POWER LOCK SYSTEM
The Di622 MARK II is compatible with either the FE lock (Canon) or FV lock (Nikon) system.
Refer to the camera owner's manual for details.
REAR CURTAIN SYNCHRO.
Nikon and some Canon camerra's set the flash for rear curtain synch. photography.
The Di622 MARK II follows the command signal of theses cameras.
RED EYE REDUCTION
Available with Nikon cameras only. A small flash beam is automatically produced for short distance portrait shots to prevent the red-eye phenomenon.
