Canon EOS R5, the latest generation of full frame non reflection camera, has been preconceived because of its powerful video capability. In fact, Canon EOS R5 is mainly a high-resolution and high-quality camera. With 45 million pixels, it is in the same pixel echelon as Nikon z7 and Panasonic s1r. However, many users on the Internet compare it with Sony a7r4. Today, let’s take a look at the image quality of Canon EOS R5 and Sony a7r4 cameras. As mentioned above, Canon EOS R5 is a 45 megapixel full frame micro single camera, and Sony a7r4 is a 61 million pixel full frame micro single camera. Seeing this, many users must think that the image quality of Sony a7r4 will be better. This is not the case. < / P > < p > it is wrong to directly equate the pixel value with the image quality of a camera. High pixels do have an advantage in resolution, but this is only one factor that affects the quality of the image. In fact, the camera’s continuous shooting, anti shake ability, focusing system and high sensitivity performance are all factors affecting the image quality. Only when these factors reach a balance point can they bring better image quality performance. < / P > < p > although Canon EOS R5 has the characteristics of high pixels, its continuous shooting speed can be on the same level as Sony A9 II, reaching the highest continuous shooting speed of 20 frames / second, surpassing the continuous shooting speed of Sony a7r4 with the highest continuous shooting speed of 10 pictures / second. In terms of continuous shooting, the EOS R5 is far better than Sony a7r4, especially when shooting sports and wildlife. < / P > < p > in terms of anti shake, EOS R5 is Canon’s first camera with anti shake capability. Like Sony a7r4, it has five axis anti shake capability. The difference is that Sony a7r4 has the highest anti shake effect of 5.5, and Canon EOS R5 has the highest anti shake effect of 8 gears. This increases the possibility of hand-held photography in dark environments, and also helps to provide more stable shooting ability for 4K and above video resolution. For the focusing part, Sony a7r4 has excellent focusing system, 567 phase focus + 425 contrast detection focus, covering an area of 74%, providing a good experience for shooting; Canon EOS It has improved the ability to take photos of birds in the second generation by focusing on the eyes of dogs and cats, and it has the ability to take photos in full focus area and dog’s eyes, which can improve the ability to take photos in full focus and focus on the dog’s eyes. At the same time, Canon EOS R5 supports up to 5940 focus points, which is an overwhelming advantage. < / P > < p > we can see that the two cameras have their own advantages in terms of configuration and performance, and these configurations are also the core factors that directly or indirectly affect the image quality of the cameras. Then we will help you better and faster understand who can have better performance in terms of image quality of the two cameras through the actual comparative test. < / P > < p > before Canon launched full pixel dual core focusing technology, Sony’s focusing system has been favored by users. Canon then launched full pixel dual core focusing technology, which significantly improved the experience of focusing. Although the focus system of Sony a7r4 is very mature and has excellent experience, Canon EOS R5 has brought the second generation full pixel dual core focusing system after upgrading. < / P > < p > the second generation full pixel dual core focusing system is more mature, and the experience of focusing has been significantly upgraded. When shooting scenery and city photography, 5940 focus points and 100% focus area coverage make it easier for users to 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 characters have been circling, they can easily and continuously focus accurately. Users do not need to worry about focusing, just press the shutter. < / P > < p > through the GIF image above, we can see the performance of Canon EOS R5 and Sony a7r4 cameras in the automatic focusing of human eye / face recognition. This technology mainly helps users to complete the focusing process more easily in video or portrait shooting. Sony has long been a manufacturer of eye / face recognition autofocus technology in its cameras, so it has a very mature technology. However, from a comparative point of view, Canon EOS R5 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 Sony a7r4, which has achieved transcendence. Sony a7r4 has lost tracking in the turning process, while canon has not. Although the major brands have now widely used eye / face recognition technology for video shooting, Canon EOS R5 camera is indeed more stable and mature in actual experience. < / P > < p > in daily photography, we can quickly change the focus through touch operation. Canon EOS R5 can select the focus position through screen touch mode and complete the focusing automatically. If the touch shutter is opened, the photographing process can be completed directly. After Sony a7r4 selects the focus by touching, the user still needs to press the shutter half to complete the focusing operation, which is more troublesome. < / P > < p > the second generation full pixel dual core focusing system brings a new experience, increases the focus recognition of animal eyes and faces, and helps EOS R5 expand the range of shooting categories again. Even when dealing with birds in cages, EOS R5 can still achieve auto focus through recognition, which is excellent. For the professional photography users who like to shoot wild animals, they can choose not only the professional high-speed Sports Camera, but also the lighter EOS R5 high-pixel camera. < p > < p > anti shake is a relatively slow step in the development of camera technology, because it is not easy to achieve excellent anti shake ability in a narrow camera space. For Sony a7r4 and Canon EOS R5 cameras, they are five axis anti shake, but the anti shake compensation effect is 5.5 and 8 gear respectively. < / P > < p > we tested the anti shake ability of the lens at 50 mm and 70 mm focus respectively, using the camera’s TV file, ISO 100 and exposure compensation 0ev. We only control the shutter speed when shooting, and the aperture is automatically determined by the camera. Therefore, the brightness of the photos below is similar. The shooting posture is hand-held and standing without any other assistance. The photo below shows the extreme exposure time that Canon EOS R and Sony a7r4 cameras can achieve stable hand-held shooting at 50 mm and 70 mm focal length. Photos beyond this time have failed. Because of the harsh test environment and conditions, we can better explain the actual anti shake ability of the two cameras. < / P > < p > it can be seen that the holding stable shooting time of Canon EOS R5 reaches 2 seconds, while that of Sony a7r4 is only 1 / 3 seconds; when the lens focal length is 70 mm, the holding stable shooting time of Canon EOS R5 is still 2 seconds, while that of Sony a7r4 is reduced to 1 / 5 seconds. The anti shake ability of the two cameras is indeed quite different. If Canon EOS R5 is used for hand-held shooting at night, a lower ISO value can be used to expose for a longer time and obtain a brighter and cleaner picture directly. < / P > < p > why can it cause such a big difference in anti shake? In fact, Canon EOS R5 uses a physical anti shake mechanism. Because its RF bayonet has a large diameter of 54mm, there is a large space reserved for the anti shake mechanism. When the space is large, the operation space that the physical anti shake mechanism can achieve is large, and the natural anti shake effect can achieve the effect of up to 8 gears. < / P > < p > in addition, Canon RF card has 12 contacts, which can realize more efficient and faster information communication. In this way, it will be more sensitive to capture information such as jitter direction, and the is anti shake technology cooperating with Canon lens will be better, so the anti shake experience brought by Canon EOS R5 will be more excellent. In the harsh environment can still achieve 2 seconds of hand-held stable exposure shooting, in the full frame camera advantage has been very obvious. < / P > < p > Canon EOS R5 is not only a high-resolution camera, but also a high-speed camera. There are some differences between Canon EOS R5 and Sony a7r4. Sony a7r4 is a pure high-resolution camera. The continuous shooting speed of Sony a7r4 can reach 10 frames / second, and Canon EOS R5 can achieve continuous shooting speed of 20 pictures / second under the electronic shutter, reaching the same file experience of Sony A9 II, that is to say, Canon EOS R5 has reached the height of professional high-speed Sports Camera in continuous shooting.
can see that Canon EOS R5 has been very awesome in its continued life. Whether JPG format, raw format or JPG + raw format three tests, we can see that Sony a7r4 quickly reached the limit of the fuselage cache, and Canon EOS R5 can continue continuous shooting operation 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. < / P > < p > 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 EOS R5 is equipped with the same digital X processor as the eos-1d x Mark III, so it is relatively easy to process 20 photos per second at 45 megapixels. < / P > < p > in the storage part, Sony a7r4 adopts dual SD card slot design, Canon EOS R5 adopts SD and cfexpress dual card slot design, so EOS R5 brings users a variety of choices. Cfexpress memory card solves the storage pressure of 20 high-speed continuous shooting at 45 million pixels, and provides the camera with such a powerful continuous shooting capacity. < / P > < p > of course, continuous shooting does not exist independently. In order to successfully capture better images, the focus system of the camera needs to be strong enough. Canon EOS R5 is equipped with the second generation full pixel dual core focusing system, which can obtain the focusing experience with obvious advantages in the current camera. With the guarantee of the focusing system, the success rate of continuous shooting of EOS R5 is not only higher, but also more wonderful moments can be captured in sports scenes. This also helps the camera itself to increase the subject matter of shooting wildlife and sports, and increase the range of coverage. < / P > < p > under the joint effect of various configurations and performances, Canon EOS R5 can bring users a better continuous shooting experience, and can also cover a wider range of photography types, so that more professional users can choose EOS R5 to replace the more expensive professional models. < / P > < p > next, let’s take a look at the performance of Canon EOS R5 and Sony a7r4 cameras in terms of high sensitivity and noise control. High sensitivity performance is one of the important factors affecting the image quality, which directly affects the dark light imaging quality of the camera. High sensitivity is closely related not only to the sensor of the camera, but also to the processor and algorithm design of the camera. < / P > < p > in order to fully understand the high sensitivity and noise control performance of the two cameras, we took two groups of photos indoor and outdoor for comparison, including JPG direct out photos and raw files. Since both cameras are full frame products, we compare the four gears from ISO 3200 to ISO 25600. Under ISO 3200, full frame cameras have excellent performance, so there is no need for comparison; above ISO 25600, full frame cameras have excellent performance
