Every so often a technology comes along that not only helps photographers and filmmakers to take shots that were not previously possible, but actually improves the quality of the end result. The Canon 球探体育比分_欧洲杯足球网乐￥在线直播5, 球探体育比分_欧洲杯足球网乐￥在线直播6 and 球探体育比分_欧洲杯足球网乐￥在线直播3 are the first Canon cameras with 5-axis In-Body Image Stabilisation (IBIS), and can deliver an industry-leading 8-stops of IS¹ when the cameras are paired with certain lenses.

The 球探体育比分_欧洲杯足球网乐￥在线直播7 is also equipped with IBIS, which delivers up to 7-stops of IS with RF-S lenses.² It is possible to achieve even more stability with certain full-frame lenses, though, as Mike Burnhill, Senior Product Specialist at Canon Europe, explains: "When using either the RF 28-70mm F2L USM or the RF 24-70mm F2.8L IS USM, for example, the 球探体育比分_欧洲杯足球网乐￥在线直播7 will deliver the same 8-stops of IS as the other cameras with IBIS. We're not expecting that many 球探体育比分_欧洲杯足球网乐￥在线直播7 users will be using more expensive pro lenses like these, though."

This unparalleled level of performance means image makers can disregard the existing rules on handheld shooting, free themselves of the tripod, shoot in previously inaccessible locations and capture incredible shake-free shots and steady video.

This groundbreaking level of image stabilisation (IS) eradicates the worry caused by setting a slower shutter speed and makes it possible to introduce creative blur while shooting fast-moving subjects, for example, without camera shake taking the edge off the sharpness. Photographers who are used to shooting interiors that tend to require long exposures and narrow apertures for extended depth of field can now consider shooting handheld with exposures lasting one to four seconds (depending on the focal length) and setting a lower ISO to preserve maximum levels of detail.

The technology has already been making waves with users. Adventure photographer and Canon Ambassador Ulla Lohmann took the Canon 球探体育比分_欧洲杯足球网乐￥在线直播5 to the German Alps to capture rock climbers abseiling into a waterfall. "It's very adventurous terrain, and you can't take a tripod with you," she says. "You also cannot put the camera on the rocks, because they are wet. I wanted to use a longer exposure to take images with a blurry waterfall behind, while the foreground was still in focus. It worked really well and I was able to shoot exposures of one second or more handheld and still get sharp images."

Fashion photographer Wanda Martin took the Canon 球探体育比分_欧洲杯足球网乐￥在线直播6 on a low-light shoot following a ballet dancer through the ornate buildings of Palermo in Sicily, and was able to shoot much longer exposures without a tripod and still portray the dancer's movements. "I managed to shoot handheld for four seconds and the background was still sharp. I couldn't believe it," she says.

To test the capabilities of the 球探体育比分_欧洲杯足球网乐￥在线直播7, wildlife photographer and content creator Dani Connor visited Spain's Andújar Natural Park to photograph and film Iberian lynx. She teamed the flagship APS-C mirrorless camera with a range of IS-equipped lenses, including the Canon RF 100-500mm F4.5-7.1L IS USM and Canon RF-S 18-150mm F3.5-6.3 IS STM.

"I was amazed by the stabilisation of the RF-S 18-150mm F3.5-6.3 IS STM with the camera," she says. "I was shooting video while I was walking and it was smooth. It was the same when I was filming from a car, even though we were going on bumpy roads. I would never have been able to get those kind of video clips with my DSLR."

Wildlife photographer Maxime Aliaga says that the sophisticated IS and other new technology in the Canon 球探体育比分_欧洲杯足球网乐￥在线直播5 are totally changing the way he shoots. "The combined in-body IS and lens IS is amazing. I don't use a tripod much at all now, other than to rest my arms when shooting for long periods with my RF 600mm F4L IS USM.

"I work a lot with orangutans in Indonesia. The light levels are low in the forests, and in the past I would have had to use a tripod to get steady shots. But now, with the IS and the high ISO performance of the 球探体育比分_欧洲杯足球网乐￥在线直播5, it's possible to shoot handheld. I'm able to react more quickly and get shots that I couldn't have taken before."

Action sports specialist Martin Bissig is equally enthusiastic about the IS performance of his Canon 球探体育比分_欧洲杯足球网乐￥在线直播5 for low-light photography. "A lot of the time I'm using fast shutter speeds to shoot action, but when I'm on an expedition I also end up taking a lot of incidental pictures to document the trip," he says. "I'm often shooting in situations where I don't have a lot of available light to work with, such as inside a temple or on a camp site at night.

"It's really great to have IBIS in my 球探体育比分_欧洲杯足球网乐￥在线直播5 in these instances, and it means that I don't use my tripod that much anymore, if at all. It has allowed me to shoot handheld for exposures that can last 2-3 seconds."

So the benefits of this groundbreaking IS performance are clear – but how does this advanced technology work?

Pairing the 5-axis IBIS-equipped 球探体育比分_欧洲杯足球网乐￥在线直播5, 球探体育比分_欧洲杯足球网乐￥在线直播6 or 球探体育比分_欧洲杯足球网乐￥在线直播3 with an IS-equipped lens can deliver 8-stops of combined IS¹. It's not the case that one IS technology is better than another. Rather, there are types of shake that lens-based IS can correct optimally and there are areas that the in-body IS is best equipped to deal with, so the combination of the two results in the best overall performance.

What is impressive in the 球探体育比分_欧洲杯足球网乐￥在线直播3 is that the systems are able to work together to produce up to 8-stops of combined IS even when the camera is shooting high-speed bursts at 30fps.

"The readout speed of the 球探体育比分_欧洲杯足球网乐￥在线直播3's electronic shutter is very fast," explains Mike. "That means you can use a shutter speed of around 1/125 sec to achieve 30fps. Image stabilisation not only has a benefit at that relatively slow shutter speed, it can also improve autofocus acquisition. Having IS means the AF point is more likely to be static on the subject than bouncing around, which improves the AF accuracy at 30fps."

Lens-based optical IS was pioneered by Canon during the film era in the 1990s on its range of EF lenses. A gyroscope detects the camera movement, while certain elements within the lens can move in response to compensate for the movement, resulting in a steadier image. Optical IS is especially effective at telephoto focal lengths, which is why it continues to serve well today.

It isn't just photographers shooting still images who benefit from cooperative IS control. Filmmakers are able to produce smoother handheld footage with Movie Digital IS enabled. "With it turned on, it can really stabilise movement when you're walking, in a similar way to a gimbal," says Mike. "Obviously the original IS systems are good but they're not really designed for you moving around as much, whereas a gimbal system is."

Movie Digital IS works by cropping the image slightly, which allows the sensor data to move around to compensate for shake or vibration. Two settings are available, each with a different crop factor.

In the Canon 球探体育比分_欧洲杯足球网乐￥在线直播, Movie Digital IS uses the lens and image sensor data together, but Canon 球探体育比分_欧洲杯足球网乐￥在线直播 System cameras that are equipped with IBIS use all three aspects – lens, IBIS and digital data – to produce enhanced stability. "The whole system is working in combination," says Mike, "with the final stabilisation on the sensor correcting for that movement that is beyond the optical system."

A firmware update for the 球探体育比分_欧洲杯足球网乐￥在线直播5, 球探体育比分_欧洲杯足球网乐￥在线直播6 and 球探体育比分_欧洲杯足球网乐￥在线直播3 also brings improved Movie Digital IS performance when using wide-angle lenses. "IBIS allows the sensor to pivot in order to correct vibrations, so the corners of the image move backwards and forwards," explains Mike. "In some situations, the edges can appear more wobbly than the centre, but the digital stabilisation firmware update will correct that movement and give a more stable image."

So this IS system has two distinct inputs – one from the camera sensor and one from the IS-equipped lens.

The gyro sensor inside the lens measures the angle and speed of any lens shake, while an acceleration sensor measures the acceleration of the movement. This information is monitored by the lens's own processor.

Inside the camera, there is another pair of gyro and acceleration sensors, plus an additional motion vector sensor on the imaging sensor itself. This data is managed by the camera's powerful DIGIC X processor.

This information is shared in real-time between the lens and sensor, so that the perfect amount of compensation can be coordinated and applied to remove any shakes. Within the lens, the stabilised optics move to counteract pitch and yaw movement, as well as movement on the X-Y axis (side-to-side movement and up-and-down movement) in the case of Hybrid IS lenses when used for still photos.

In the camera body, the sensor itself is moved via a highly precise magnetic system to counteract roll, X-Y and pitch and yaw. The latter is done by real-time collaboration through the high-speed RF mount communication system, which gives the Canon 球探体育比分_欧洲杯足球网乐￥在线直播 System its distinct advantage.

Key to the IS system is not only the electronics inside the cameras, but also the innovative RF lens mount, which enables much faster communication between camera and lens. In order for the IS to work accurately, the lens and the camera need to share a lot of information, and the RF mount is designed to communicate large amounts of information in real-time.

The other crucial element is the mechanical and optical design of the RF mount: at 54mm in diameter, it gives the sensor more room to move, enabling a greater degree of motion correction.

For the engineers at Canon, their greatest challenges lay in designing the cooperative control between optical IS and in-body IS, and utilising the high-speed camera and lens communication to achieve this. The system requires extremely accurate data, so the engineers added an inertia sensor and motion vector information.

The RF mount's wide diameter and short flange back has also enabled Canon to produce lenses with a large image circle. A larger image circle gives the sensor more room to move without risk of the image getting cut off, which can sometimes occur with a narrower lens mount. The large image circle therefore allows the camera's In-Body Image Stabilisation to deliver up to 8-stops of IS when using lenses such as the RF 28-70mm F2L USM and RF 85mm F1.2L USM, which do not feature built-in optical stabilisation.

Because Canon 球探体育比分_欧洲杯足球网乐￥在线直播 System cameras are also compatible with EF lenses (via any of the range of EF-球探体育比分_欧洲杯足球网乐￥在线直播 Mount Adapters), another engineering feat lay in designing for optimal IS regardless of whether the cameras with IBIS are paired with an RF lens, EF lens, IS-equipped lens or non-IS lens. The table below summarises how the system works in unison to provide 5-axis correction when paired with these different lenses.

As you can see, photographers and filmmakers using existing EF lenses and RF lenses without IS can still benefit from the IBIS in the 球探体育比分_欧洲杯足球网乐￥在线直播3, 球探体育比分_欧洲杯足球网乐￥在线直播5, 球探体育比分_欧洲杯足球网乐￥在线直播6 and 球探体育比分_欧洲杯足球网乐￥在线直播7, while RF lenses with optical or hybrid IS benefit from both systems (although effectiveness does vary on a lens by lens basis).

Of course, the best advantage is realised when the lens and the camera work together. This way, their strengths are combined to reduce all the different types of camera shake that can occur over different focal lengths and in different scenarios, helping you to reimagine handheld shooting and more.
