Intuitive user interface for ease of useSpecifications
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

When it comes to action, photography and taking risks, Marcel Lämmerhirt is your man. Discuss anything related to these areas and it’s hard not to notice the anticipation and enthusiasm building in Marcel. With a particular passion for speed, Marcel has photographed everyone from snowboarders to professional cliff divers, and journeyed everywhere from the Swiss glaciers to Tokyo, seeking his perfect shot.See the entire article on the iamNikon Blog.
So, in November 2015, it is no surprise that we approached Marcel to see what he could do with the Nikon D500. It didn’t take long for him to come up with an idea: to photograph Alvaro Dal Farra freestyle motocross athletes in the DaBoot Superpark, Lentiai, Italy. It was to be one of the most challenging and exhilarating shoots he’s experienced so far. In this guest blog, he revisits this experience, sharing the unexpected challenges he & his crew came across and how they overcame them.
It's definitely true that there's a point, as shutter speeds get progressively faster, that the shake-prevention qualities of Image Stabilization really have little or no added effect. In other words, if you take a 600mm f/4L IS lens, mount it on a monopod (definitely NOT a totally stable platform, obviously!), and shoot at 1/8000th of a second, it's absolutely arguable that I.S. has no direct benefit in terms of minimizing camera shake. I think we can agree that with or without I.S., most users could get consistently shake-free pictures with that monopod-mounted 600 at 1/8000th of a second.Question: Extending your engineering discussion … I understand the benefit of IS to the AF system. What about when the subject is moving rapidly and IS is trying to hold the image still? It seems to me that the AF system would be better having the exact subject framing present at the moment it is making its decision. And, isn’t the addition of Mode 3 supporting this concept?
Turning I.S. off in situations like that (maybe not at 1/8000th, but perhaps at 1/2000th or thereabouts) will save a small amount of camera battery power... probably a minor consideration to most users, but perhaps a bit more relevant to someone working with a camera like an EOS Rebel or the new EOS 77D, which have smaller batteries with less capacity than, say, an EOS-1D X Mark II. Definitely a potential consideration for anyone shooting with a mirrorless camera like an EOS M5, which *always* have less battery life per charge, since they use more power-hungry LCD monitors or electronic viewfinders.
For sports, action, wildlife and so on, keep in mind the potential benefits of a more stable image in your viewfinder. Even if your shutter speed pretty much precludes any problems with camera shake, if I.S. is active and set to Mode 1 or Mode 2, you see a steadier, more stable view in your finder when working on a monopod or a gimbal-type tripod mount. This can be beneficial in a number of ways, from subtle benefits in frame-to-frame composition when following moving subjects, to being able to keep an AF point solidly upon a detailed area of a moving subject.
For those who consider the effect of visible stabilization during shooting to be an annoyance (for instance, it may seem to delay rapid lens movements to follow a moving subject), there is Mode 3 on lenses like the 400/2.8 II or 600/4 II. This is a specialized I.S. mode that does provide the shake-prevention effects, but ONLY when the shutter button is **fully** depressed, and a shot is actually being taken. Otherwise, at all other times, the effect of I.S. is disabled, although stabilization detection is continually taking place between shots, and the lens's moveable stabilization optical elements are held in a non-locked, "ready" position. In other words, in Mode 3, you don't SEE the effect of stabilization, but it still is there when you actually shoot each picture.
Here's one that never gets discussed among sports, action and wildlife shooters, but which our engineers HAVE said is a benefit of Image Stabilization, even at the fastest shutter speeds. Because Canon's I.S. is optical, if you do have your stabilization set to Mode 1 or 2, where it's continually active, the viewfinder isn't the only place where a steady, stabilized image is seen. The FOCUSING SYSTEM also gets the same benefit of a clean, steady and stabilized look at the subject, too. This matters, especially during fast, high-speed sequences, and even more so if/when you're shooting subjects that are (a) moving aggressively, and (b) may not have tons of detail, contrast and texture to them. The AF point or points being used must see some detail, and during a fast, AI Servo AF sequence, have less than 1/10th of a second in cameras like an EOS 7D Mark II, or certainly an EOS-1D X model, to read the subject between each frame. By using I.S., regardless of how fast the actual shutter speed is, the AF system gets a cleaner, steadier look at the subject during that interval between each frame, and is more likely to be able to read subject detail and provide continuous AF where most or all frames in a sequence are sharp (in terms of FOCUS).
I know there's a body of thought out there among some sports shooters that since they're already at fast shutter speeds, I.S. isn't needed, but they should contemplate what I just said. And, there's a body of thought that I.S. being active can slow down AF... I've directly asked our leading engineers that, and been told emphatically that this is NOT true, regardless of anecdotal "evidence" some shooters may feel they've experienced.
Bottom line, my basic suggestion would be to leave it on, unless you absolutely have deliberate reasons for not doing so. Consider the above points; remember the potential impact of Mode 2 (panning mode, so to speak) and Mode 3 (stabilization, but without visible effects in the viewfinder); and we do still suggest turning I.S. off if you know you'll be mounted to a completely rigid, locked-down position.
Like I said, if you have distinct reasons for shutting I.S. off, go for it. But, in the VAST majority of action-type situations, especially with human-subjects (football and similar sports), the likelihood the movement would be SO sudden that what I.S. projects into the viewfinder and the subject's actual composition at the same time or an instant later would be extremely different is probably pretty slim. At least, in my experience. Might be a little different for someone photographing small birds in flight with a big lens, from relatively close distances.So, there you have it. Even when using shutter speeds fast enough to negate camera shake, leaving image stabilization "On" is generally a good idea. If nothing else, it's providing a stable viewfinder scene for you and the AF system, allowing for easier tracking of moving subjects.
The addition of Mode 3 *might* bring some benefits if and when you feel this difference in what you see vs. what you shoot is happening, but it's not the sole reason for its existence.
Most of the time, I'm very comfortable to suggest using I.S. Mode 1 or 2, even at fast shutter speeds, and with nearly all moving subjects. But I repeat, if for whatever reasons you feel it's hindering your ability to compose in real time, either switching to Mode 3, or turning I.S. off completely, remain options as well.
