Accessories: Case, Flash stand(FS-31)


Intuitive user interface for ease of use

The new dot matrix liquid crystal display is incorporated for this flash. Moreover, the D-Pad and dial on the side of the flashgun make changing settings, such as TTL auto exposure system, wireless flash, FP flash and rear-curtain sync, on the main screen and setup menu displayed on the LCD easier than ever. The flash is designed to disengage easily by one-click on the shoe lock lever. In addition, a flash sync terminal and notification beep sound when the flashgun is fully charged improves ease of use.

Three light distribution modes

The flash is designed to work in three light distribution modes. Normal emission mode has basic light distribution for general photography, and another mode prioritizes guide number to obtain an even larger output. Flat light distribution mode has a characteristic of uniform light distribution by reducing the fall off of peripheral light. It is possible to select the mode in accordance with the purpose.

Wireless TTL Flash Function

The wireless TTL flash function will adjust the desired flash exposure automatically by flash light even if the EF-630 is detached from the camera. Remote control operation is possible between the camera and flash.

When multiple flash units are used, the camera calculates the correct exposure automatically.

* It can be used with EF-610 DG SUPER and for wireless shooting with a built-in flash of a camera which has master function for wireless flash shooting.

Rear-curtain Sync flash function for natural representation of motion

When photographing a moving subject, the Rear-curtain Sync mode allows the flash to be triggered immediately before the rear-curtain of the shutter closes. Unlike Front-curtain Sync, this mode records blurred trails behind a moving subject rather than in front for a more natural expression of motion.

AF assist light for accurate auto-focus in low light conditions

Accurate AF may not be possible in dark conditions. However, the AF assist light of the EF-630 allows effective AF between approximately 0.7m and 10m.

* AF assist light is not available with some camera models.

Modeling Flash function to check for shadow

The EF-630 also offers a modeling flash function, enabling the user to check for reflections and shadows before taking a photograph.

Notification beep sound

When the notification beep sound is turned on by the switch at the front of the flash, it is possible to check the status of flash such as whether it is fully charged, exposure is ok, as well as error alert only by the sound without looking at the LCD display.

Catch Light Panel

This flash is equipped with a built-in catch light panel, which can highlight the eyes of the subject when the bounce flash mode is activated.

Guide Number 63 offering a greater output of light

The maximum guide number is 63 for a high light level (when the focal length is 200mm). It is possible to change the illumination angle from 24mm wide to 200mm telephoto. It also covers an angle of a 17mm when used with the built-in Wide Panel.

Bounce-flash function with movable flash head

The flash head of the EF-630 can be tilted up by as much as 90°and can swivel both left and right by 180°. Bounce photography, where light is reflected off a white wall, ceiling or a reflector increases the range of photographic expression. The flash head can also be tilted down by 7°for close-up shots.

Slave Flash Function

Slave Flash can be used with all camera models and it allows the flash to be fired away from the camera by the master unit though it is not possible to set flash exposure automatically.

The Designated Slave function for EF-630 allows the photographer to use two or more EF-630 flash units simultaneously. It is possible to designate flashguns by using different channel settings. In the Normal Slave mode, it is also possible to use the camera’s built-in flash or another flash unit as the Master.

* It can be used with other EF-630 and EF610 DG SUPER with different mounts.

FP Flash function for high shutter speeds

Cameras with flash focal plane shutters cannot perform flash photography at shutter speeds faster than the fixed synchronization speed as it is usually limited to coincide with the fully open shutter. The FP flash function makes flash photography possible at shutter speeds greater than the fixed synchronization speed. When the lens diaphragm is set to larger apertures to limit depth of field in synchronized daytime shooting, high shutter speeds can be used to balance the daylight and the flashlight at any shutter speed.

*This function is not available with some camera models.

Multiple Flash Photography

In a single frame it is possible to capture the frozen-in-motion image of a subject by a series of light bursts.

Manual flash power level control

The flash power level of the EF-630 can be set manually from 1/1 to 1/128 in 1/3 EV increments to meet the photographer’s needs.

Custom Mode Function

The Custom Mode Function is available to register two settings with the photographer’s preference. It is easy to set it with D-Pad and dial on the side of the flashgun.

Auto Power-Off function prevents power waste

To conserve battery life, the EF-630 will automatically turn off after a certain period of time of inactivity.

Synchronic Terminal

The EF-630 is equipped with a Synchronization Terminal to connect a camera with the commercially available synchronization cable.

Regular firmware updates

Photographers can update the firmware via the newly developed optional FLASH USB DOCK FD-11(Sold separately). The firmware can be updated by attaching the EF-630 to the FD-11 and then connecting the FD-11, via a USB cable, to a personal computer on which the exclusive software SIGMA Optimization Pro has been installed.
