High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4

   Canon EOS R5, the latest generation of full-frame mirrorless camera, has been preconceived because of its powerful video capabilities. In fact, Canon EOS R5 is mainly a high-resolution, high-quality camera, 45 million pixels make it in the same pixel echelon with Nikon Z7, Panasonic S1R, but many online users compare it with Sony A7R4. Today, let’s take a look at the picture quality of Canon EOS R5 and Sony A7R4.

High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4

  High pixels do not mean high picture quality

   As mentioned above, the Canon EOS R5 is a 45-megapixel full-frame mirrorless camera, and the Sony A7R4 is a 61-megapixel full-frame mirrorless camera. Seeing this, many users must think that the image quality of the Sony A7R4 will be better. This is not the case.

   directly equating the pixel value with the picture quality of a camera, this concept is wrong. High pixels do have advantages in resolution, but this is only a factor that affects image quality. In fact, the camera’s continuous shooting, anti-shake ability, focusing system and high sensitivity performance are all factors that affect the image quality. These factors can reach a balance point to bring better image quality performance.

  Although Canon EOS R5 has the characteristics of high pixels, it is The continuous shooting speed is on the same level as the Sony A9 II, reaching a maximum continuous shooting speed of 20 frames per second, surpassing the Sony A7R4’s maximum continuous shooting speed of 10 frames per second. EOS R5 also far exceeds the level of Sony A7R4 in continuous shooting, especially when shooting sports and wildlife will play a key role.

 In terms of anti-shake, EOS R5 is Canon’s first camera with body anti-shake capability, and it has five-axis anti-shake capability like Sony A7R4. The difference is that the Sony A7R4 has a maximum anti-shake effect of 5.5 stops, and the Canon EOS R5 has a maximum anti-shake effect of 8 stops. This increases the possibility of handheld photography in more dim environments, and can also help 4K and above 4K resolution videos to provide more stable shooting capabilities.

   For the focusing part, the Sony A7R4’s focusing system is excellent, with 567 phase focus points + 425 contrast detection focus points, covering an area of ​​74%, which provides a good experience for shooting; Canon EOS The R5 is equipped with the second-generation full-pixel dual-core focusing technology, the focus area coverage is increased to 100%, with more mature eye recognition, and the ability to focus and recognize the eyes and faces of cats, dogs, birds and other animals, whether it is Taking photos or recording videos, the focus ability has excellent performance and can meet the needs of more diverse shooting types. At the same time, Canon EOS R5 supports up to 5940 focus points, which is an overwhelming advantage.

   As you can see, the two cameras have their own configuration and Performance advantages, and these configurations are also the core factors that directly or indirectly affect the image quality of the camera. Then we will pass the actual comparison test to help you better and faster understand who owns the image quality of the two cameras. Better performance.

   Focus: The second-generation full-pixel dual-core technology is powerful and easy to use

   Before Canon launched the full-pixel dual-core focus technology, Sony’s focus system has been favored by users. Canon subsequently introduced the full-pixel dual-core focusing technology, which significantly improved the focus experience. Although the Sony A7R4’s focusing system is very mature and the experience is excellent, I did not expect Canon EOSR5 to bring an upgraded second-generation full-pixel dual-core focusing system.

   The second-generation full-pixel dual-core focus system is more mature, and the focus experience has also been significantly upgraded. When shooting landscape and urban photography, 5940 focus points and 100% focus area coverage allow users to more easily complete various tricky focusing operations. When shooting people, especially in fast-moving scenes, the new focusing system can recognize human eyes and faces more accurately and quickly. Even if the person is always in a circle, it can easily and continuously follow the focus accurately. The user does not need it at all. To worry about focusing, just press the shutter.

   Through the above GIF picture, you can see the performance of Canon EOSR5 and Sony A7R4 cameras in eye/face recognition autofocus. This technology mainly helps Users can more easily complete the focusing process during video or portrait photography. Sony has long started to incorporate human eye/face recognition autofocus technology in its cameras, so it already has a very mature technology. But from a comparison point of view, Canon EOSR5 has caught up, and its performance in human eye recognition is also very mature. In the process of turning head recognition, it is even better than the Sony A7R4, achieving surpassing. Sony A7R4 loses tracking in the process of turning head, but Canon does not. Although all major brands have widely used human eye/face recognition technology for video shooting, in actual experience, the performance of Canon EOSR5 camera does appear to be more stable and mature.

The Sony A7R4 can only change the focus area by touching

   When taking pictures in daily life, we can quickly change the focus point by touching. Canon EOSR5 can select the focus point position by touch on the screen and automatically complete the focus, if the touch shutter is turned on, the photo process can be completed directly. After the Sony A7R4 selects the focus point by touch, the user needs to half-press the shutter to complete the focus operation, which is more troublesome.

   Focal length: 70mm  Aperture: f/2.8  ISO sensitivity: 100 Exposure time: 1/400  Exposure compensation: 0EV  White balance: Auto

   The second-generation full-pixel dual-core focusing system brings a brand new experience, adding focus recognition to animal eyes and faces, helping EOSR5 once again expand the scope of shooting types. Even when dealing with birds in a birdcage, EOSR5 can still perform autofocus through recognition, which is excellent. For professional photographers who like to shoot wild animals, the choice for shooting outside is no longer a single professional high-speed sports camera, but also a lighter EOSR5 high-pixel camera for shooting.

   Anti-shake: 8-speed body anti-shake is not a mere name

   Anti-shake is the slower development of various camera technologies, because it wants to achieve excellent anti-shake It is not easy to realize the shaking ability in a small camera space. Speaking of Sony A7R4 and Canon EOSR5 cameras, they are all five-axis anti-shake on the fuselage, but the anti-shake compensation effect is up to 5.5 and 8 respectively.

High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4

   We tested the 50mm focal length and 70mm focal length of the lens. Shake ability, use the camera’s TV file, ISO 100, exposure compensation 0EV. We only control the shutter speed when shooting, and the aperture is automatically judged by the camera. Therefore, the brightness of the following photos is relatively similar, and the shooting posture is handheld standing shooting without other assistance. The photos below show the extreme exposure time that Canon EOSR and Sony A7R4 cameras can achieve handheld stable shooting at 50mm and 70mm focal lengths. Photos beyond this time will fail. Since our test environment and conditions are relatively harsh, it can better illustrate the actual anti-shake capabilities of the two cameras.

High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4

   It can be seen that at the 50mm lens focal length, the handheld stable shooting time of Canon EOSR5 reaches 2 seconds, Sony A7R4 Only 1/3 second; in the 70mm lens focal length, the handheld stable shooting time of Canon EOSR5 still maintains 2 seconds, Sony A7R4 is reduced to 1/5 second. The anti-shake capabilities of the two cameras are indeed quite different. If you use Canon EOSR5 for handheld shooting at night, you can use a lower ISO value to expose for a longer time and directly get a brighter and cleaner picture.

Why can    cause such a big difference in image stabilization? In fact, Canon EOSR5 uses a physical anti-shake mechanism. Because its RF mount has a 54mm large-diameter design, the space reserved for the anti-shake mechanism is very large. When the space is large, the physical anti-shake mechanism can achieve the operation space for anti-shake, and the natural anti-shake effect can achieve the effect of up to 8 gears.

High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4

   In addition, the Canon RF mount has 12 contacts, which can be realized More efficient and faster information communication, so that it will be more sensitive to capture information such as jitter orientation, and the IS anti-shake technology of the Canon lens will be better, so the anti-shake experience brought by Canon EOSR5 will be even better. It can still achieve 2 seconds of handheld stable exposure shooting in harsh environments. The advantages in full-frame cameras are already very obvious.

  Continuous shooting: 20fps allows EOSR5 to shoot more subjects

   Canon EOSR5 is not only a high-resolution camera, but also a high-speed camera. This is slightly different from the Sony A7R4. Sony A7R4 is simply a high-resolution camera. The continuous shooting speed of the Sony A7R4 can reach 10 frames per second, and the Canon EOSR5 can achieve a continuous shooting speed of 20 frames per second under the electronic shutter, which has reached the same file experience of the Sony A9II, which means that the Canon EOSR5 has touched on the continuous shooting. The height of a professional high-speed sports camera.

   In the endurance part of continuous shooting, you can see that Canon EOSR5 performs very well. Whether it is JPG format, RAW format or JPG+RAW format in the three tests, it can be seen that Sony A7R4 quickly reached the limit of body cache, and Canon EOSR5 can continue continuous shooting if the author does not release the shutter. , So it can better meet the long-term continuous shooting operation in wildlife photography or sports photography. Of course, this has something to do with the camera’s processor, body cache and storage medium.

  Because it is a high-pixel camera, the pressure on the processor, cache, and storage is greatly increased at such a high continuous shooting speed. Canon EOSR5 is equipped with the same DIGICX processor as EOS-1DXMarkIII, so it is relatively easy to process 20 pictures per second at 45 million pixels.

   Of course, continuous shooting does not exist independently. If you want to successfully capture a better picture with continuous shooting, you need the camera’s focusing system to be powerful enough. Canon EOSR5 is equipped with a second-generation full-pixel dual-core focusing system, which can obtain a focus experience with obvious advantages among current cameras. With the guarantee of the focusing system, the EOS R5 not only has a higher success rate for continuous shooting, but it can also capture more exciting moments in sports scenes. This also helps the camera itself increase the shooting of wildlife and sports themes, and increase The scope of coverage.

   Under the combined effect of many aspects of configuration and performance, Canon EOS R5 can bring users a better continuous shooting experience, and it can also explore a wider range of photography types, allowing more professional users to choose EOSR5 replaces the original more expensive professional models.

  High sense: EOSR5’s night shooting ability is significantly improved

   Next, let’s take a look at the performance of Canon EOSR5 and Sony A7R4 in terms of high-sensitivity noise control. High-sensitivity performance is one of the important factors affecting image quality, which directly affects the camera’s low-light imaging quality. High sensitivity is not only closely related to the camera’s sensor, but also closely related to the camera’s processor and algorithm design.

   In order to fully understand the high sensor noise performance of the two cameras, we took two sets of photos indoors and outdoors for comparison. The comparison included JPG straight-out photos and RAW format files. Since both cameras are full-frame products, we compare four gears from ISO 3200 to ISO 25600. Below ISO 3200, full-frame cameras have excellent performance, so there is no need for comparison; above ISO 25600, full-frame cameras will have a significant deterioration in image quality, so we will not compare them.

  Indoor In the low-light environment comparison, we can see that the performance of Canon EOSR5 is better than Sony A7R4, whether it is RAW format file or JPG straight out photo. Especially at ISO 3200, we can see that Canon EOSR5 has a very good picture performance, and Sony A7R4 has more noise. Coming to the ISO 12800 and ISO 25600 levels, you can see that the two cameras still retain the details, but the Sony A7R4 has very obvious color noise, and the Canon EOSR5 has a very good noise control level. In other words, even at the ISO 25600 level, the low-light image quality of Canon EOSR5 is still acceptable.

High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4

  Outdoor In the test, we can see that the low-light image quality of the two cameras is basically the same as that of the indoors. Sony A7R4 has more noise than Canon EOSR5 in every ISO level. Especially with ISO 12800 and ISO 25600, the color noise in the Sony A7R4 picture has severely affected the viewing experience, while the performance of Canon EOSR5 is still very good, and ISO 25600 is still available.

  RAW file records the raw data of the environment, so it reflects the level of the two camera sensors. It can be seen that on the premise that the sensors are all full-frame specifications, the Canon EOSR5 sensor has a stronger strength in the low-light image quality performance, especially it is still available under ISO 25600, which has surpassed the level of many products of the same level. .

   JPG straight out photos are photos taken by the camera and processed by the in-camera processor through a set algorithm. Therefore, the noise control level of JPG photos reflects the ability of the processor and whether the algorithm is excellent . Since Canon EOSR5 uses the same DIGICX processor as the higher-level Canon EOS-1DXMarkIII, it is expected that the noise control ability has such a performance. This is also an important factor why Canon EOS R5 JPG photos can still achieve ISO 25600.

   purchase: I will choose the all-around camera EOSR5

   In terms of price, Sony A7R4 and Canon EOSR5 are products at the same price, so the two cameras are put together for purchase and comparison belongs to users Normal operation.

   Both Canon EOS R5 and Sony A7R4 cameras seem to be high-resolution, high-quality models, but they are not. The Sony A7R4 is indeed a pure high-pixel, high-quality camera, and it is also the holder of the highest pixel in the full-frame field. There is no doubt about it; but Canon EOS R5 is not only that, it also has obvious competitive advantages among civilian-grade cameras. Video specifications, anti-shake ability, continuous shooting performance and focus system, so we can call Canon EOS R5 an all-round camera.

High-definition showdown: who is the winner of Canon EOS R5 and Sony A7R4

   It is precisely because of the different camera capabilities that directly affect the two cameras The suitable population distribution of the camera. Sony A7R4 is suitable for a single user. Canon EOS R5 is suitable for a wide range of users. It can not only meet the needs of landscape photography and commercial shooting users, but also meet the needs of professional video studios, wildlife photography and sports photography related personnel. . The ability to adapt to such a rich variety of shooting is enough to show that Canon EOS R5 is an all-round camera.

   If the price is the same, I prefer to choose an all-round camera. Because Canon EOSR5 can make photography or video shooting easier for the author, a lot of work can be done completely relying on the camera, why not do it.
