Di466 responds to Canon's E-TTL, E-TTL II system, and Nikon's i-TTL system.
Those new digital TTL flash systems control the flash light with greater precision and stability.

The TTL flash power level is pre-set for reasonable exposure at factory. You can, however, reset the power at the desired exposure level, in +-3/4Ev. by 1/4Ev increments.
The preset value is memorized as your personal standard after switching the unit off.
This unique system for customizing your level settings, called MY TTL, is a feature exclusive to Nissin.
The usual TTL flash level compensation works based on this customized level.

Back_panel 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.

BATTERY MAGAZINE Quick Loading System
Battery2 sec. loading by Nissin original battery magazine.
A convenient battery magazine has the slots for all four batteries in the same direction, with an anti-reverse loading guide so that the batteries can be correctly inserted every time, even in poor lighting. An extra battery magazine is separately available.

The oscillation circuit produces frequencies that are inaudible to humans.
The sharp humming of the oscillator can cause irritation, which may be quite severe in certain settings.

RemoteThe wireless remote flash system of Di466 works for either analogue (single flash) and digital (pre-flash) flash systems. Variable power in six steps is available.
Place the Di466 off the camera and the flash synchronizes with the master flash placed on your camera. This wireless remote flash system is called slave flash technology and is often used for a creative lighting efficiency.
Use the camera's built-in flash, the manufacturer's original flash, or Di466 as the master flash. Place one or more Di466 flash units away from the camera.
Off-camera flash photography offers a different lighting configuration.
Use multiple Di466 flash units to achieve professional flash techniques.

FilterWidepanelLight 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.
The flash beam covers the frame from 14mm (with a wide angle diffuser built-in) to70mm of the digital lens.(*) For a longer lens, the flash head reflector position stays at 70mm.
It turns 90 degree upward for bounce lighting.
The flash head also stores a small reflection panel for a fill-in shot.
(*) The focal length for the traditional SLR camera is to be multiplied by a factor of 1.5 times.


Energy saving system
The Di466 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 automatic turn off timing is prolonged to 60 minutes.

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 down to 1/32nd power in 1.0Ev increments.

AF Assist beam
In darkness or dim light conditions, the Di466 beams an orange LED light to create a sharp contrast to enable the camera's focus sensor to focus easily on the subject.

Color Filter Guide
The Di466 has a guide rail for filters. Color filters and density filters can slide into the slot provided at the front of flash window.

Flash Power Lock system
The Di466 is compatible with either the FE lock (Canon) or FV lock (Nikon) system.
Refer to the camera owner's manual for details.

Rear curtain synch. system
Nikon and some Canon cameras set the flash for rear curtain synch. photography.

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.
