Is the Canon camera EOS R3 worth buying? Parameter Configuration of Canon Camera EOS R3

On September 14, Canon launched EOS R3, a micro-camera from Quan Huafu, which attracted much attention. Canon EOS R3 adopts Quan Huafu back-illuminated stacked CMOS image sensor independently developed by Canon, and it is also the first EOS digital camera with Canon eye-controlled focusing technology. Here I will give you a detailed introduction of this EOS R3 to help you solve more problems.

EOS R3 is not only equipped with high-speed continuous shooting with a maximum of about 30 frames per second, 6K 60P RAW short film shooting, jitter compensation effect of about 8 levels, strong detection/tracking focusing and other excellent performances, but also has the necessary reliability, durability and network connectivity for professional photography, which can meet the needs of professional photographers to use EOS- 1D X series or other digital SLR cameras. It also provides more choices for micro-camera users to take photos or make short films, expands the shooting field, captures the wonderful moments that were difficult to shoot in the past, and becomes an ideal weapon for sports photography, news photography, ecological photography and video shooting.

EOS R3 is a product that pays tribute to the classic and continues the classic. EOS-3 in film era was launched on 1998, which is a high-end SLR camera for professional users and senior photographers. Nowadays, the legend of 3 has been reopened in the digital age, and EOS R3 has opened a new chapter in this classic series.

Excellent high-speed response performance

EOS R3 adopts Quan Huafu back-illuminated stacked CMOS image sensor newly developed by Canon, which not only greatly improves the light collection efficiency, but also has the ability to read signals at high speed. Combined with DIGIC X digital image processor, which can quickly process a large amount of data, the speed of continuous shooting is greatly improved. EOS R3 can achieve high-speed continuous shooting (autofocus/automatic exposure tracking) up to about 30 frames per second under electronic shutter; Under the mechanical shutter, the continuous shooting speed also reaches the highest about 12 frames/second (autofocus/automatic exposure tracking). The electronic shutter with greatly improved performance can be used as an ordinary shutter, and it is more relaxed and confident when facing various dynamic subjects. Electronic shutter can release the shutter quietly, and can be widely used to shoot wild animals with high vigilance, or scenes that need to be kept quiet such as stage performances, concerts and sports competitions. There is no shutter sound interference, which improves the shooting success rate. In order to meet the storage requirements of high-speed continuous shooting, EOS R3 adopts dual-card slot design, one is CFexpress(Type-B) memory slot which can read and write data at high speed, and the other is SD (UHS-II support) memory slot, so the image recording is both high-speed and reliable.

Thanks to the greatly improved electronic shutter performance, the jelly effect has been better controlled, and the ultra-high-speed shutter with the highest speed of 1/64000 seconds has been realized. The shortest time lag of the electronic shutter is only about 20ms, which is convenient for shooting portraits with a large aperture lens in strong sunlight or freezing high-speed dynamic moments that cannot be captured by the naked eye. EOS R3 is also the first EOS model to support flash photography when using mechanical/electronic front curtain/electronic shutter for continuous shooting. In addition, the mechanical shutter of this machine is durable for about 500,000 times.

EOS R3 is equipped with a new organic light-emitting diode electronic viewfinder of about 5.76 million points independently developed by Canon, which can achieve a refresh rate of 1.20 frames per second, and can clearly display fast-moving subjects. The newly developed auxiliary function of analog view of optical viewfinder can display the effect close to that of optical viewfinder, making the observation effect more natural. With the high brightness performance of electronic viewfinder and Canon HDR image processing technology, the viewfinder can get a larger dynamic range and show more light and dark details when displaying pictures. At the same time, EOS R3 has also realized that the viewfinder image has no black screen display when using continuous shooting. When performing high-speed continuous shooting on the subject with intense movement, it is easier to grasp the action of the subject and concentrate on capturing wonderful moments.

EOS R3 takes only a short time of about 0.4 seconds to start. Photographers can safely shut down at ordinary times, and when it is predicted that there is a shooting opportunity, they can quickly start up and enter the standby state.

Eye control focusing and powerful tracking focusing.

Canon's first camera equipped with eye control focusing function is the film SLR camera EOS 5 QD introduced by 1992. At that time, an autofocus system that could detect the photographer's line of sight and determine the focus position from it was still rare. Nowadays, based on powerful image processing technology and high-speed processing performance, coupled with the display performance of high-performance electronic viewfinder, Canon once again introduces eye-controlled focusing into EOS R3, and the range, accuracy and speed of eye-controlled focusing have been greatly improved. By installing an infrared LED lamp and a line-of-sight sensor in the viewfinder, EOS R3 can accurately identify the line-of-sight position of the pupil, support photographers with naked eyes and glasses, and display eye control marks on the detected line-of-sight position. The photographer can automatically focus on the position of the eye control mark by pressing the shutter half, and the man-machine integration is very fast. After the photographer locks the subject with his eyes, the camera can also identify the subject efficiently and automatically optimize the focus position. This function is very effective for selecting target subjects from multiple subjects, which opens up a brand-new shooting operation experience.

EOS R3 has powerful object tracking performance and supports high-speed continuous shooting up to about 30 frames per second. When tracking, you can focus on the whole screen area. Capture the subject with accurate autofocus points up to 1053 partition in a large range. EOS R3 further strengthens the object detection algorithm and improves the detection ability through deep learning technology. For example, human detection algorithm can improve people's detection ability in complex athletic events, such as gymnastics, in a short time. The human head detection algorithm improves the detection ability of single/double snowboarders when their faces are covered by helmets or goggles. Human eye detection has also been strengthened, improving the detection performance when the face is covered by shadows, wearing makeup, wearing a mask or sideways. In addition, in addition to the animal identification that can identify the eyes, faces and bodies of cats, dogs and birds, it also adds the identification of four-wheeled vehicles, motorcycles and some helmets for racing.

EOS R3 is equipped with the second generation full-pixel dual-core CMOS AF. When it is used with some compatible lenses, the focus area can cover the image sensor up to about 100% while keeping tracking. 100% (level? Vertical) area, covering the visual range of the picture. EOS R3 provides 1053 auto-selected focus frames and 4779 auto-focus points that can be selected manually. The fastest autofocus speed is about 0.03 seconds, which is the fastest among EOS micro-cameras. In addition, the minimum brightness of the auto-focus of this machine has reached EV -7.5. For dim subjects that were difficult to see through the optical viewfinder in the past, the electronic viewfinder can automatically adjust the brightness to make them clearly visible.

High sensitivity? High precision image quality

It is one of the design concepts of EOS R3 to achieve high speed while pursuing high quality of each image. Quan Huafu back-illuminated stacked image sensor independently developed by Canon has about 2,465,438+megapixels. With the help of high-speed image processing of high-performance DIGIC X digital image processor and RF lens with high optical quality, the configuration is optimized, which improves the definition, noise performance and optical performance, and presents users with high-quality images with rich details.

EOS R3 adopts a brand-new stacked CMOS image sensor with Quan Huafu backlight, which can greatly improve the light collection rate. The general sensitivity reaches a wide range of ISO 100- 102400, and the extended sensitivity reaches ISO 204800. Powerful high-sensitivity performance makes it easier for photographers to improve their sensitivity, and high-speed shutters can also be used in scenes with insufficient light, which are widely used for indoor and night shooting. Image stabilization is helpful to realize night scene and dark scene shooting.

EOS R3 has built-in anti-shake function of the fuselage, and it can obtain powerful anti-shake effect with the lens without optical anti-shake, which greatly improves the success rate of hand-held shooting. With a compatible RF lens with optical anti-shake, the anti-shake of the fuselage can be matched with the optical anti-shake of the lens, providing the highest level 8 hand shock compensation effect.

EOS R3 benefits from the high-speed processing ability of DIGIC X digital image processor, and can optimize digital lens in real time when continuous shooting is performed in high-speed continuous shooting+mode. The machine also supports the simultaneous use of automatic brightness optimization and highlight tone priority. The automatic white balance algorithm is enhanced by deep learning technology, which will improve the automatic white balance in natural green scenes with many plants and grasses.

Professional short film shooting

EOS R3' s short film recording specification is as high as 6k59.94p/50.00praw, and 6K RAW short film adopts uncut horizontal angle of view, which can give full play to Quan Huafu's easily blurred background and make full use of the lens' horizontal angle of view, which provides convenience for shooting grand scenes. 6K high-resolution images provide twice the picture definition of 4K images and nine times that of full HD images, which can provide users with rich image details. The 4K or full HD images made on the basis of 6K RAW short films can simulate the translation and push-pull effects of the lens by local cropping without compressing the image quality, which is also very helpful for the digital stability of the picture. In addition, the camera also supports 6K/5.6K oversampling to generate high-definition 4K short films, and shoots119.88p/100p (NTSC/PAL) 4K short films at high frame rate. All modes can be used for short film servo autofocus/object tracking autofocus.

EOS R3 supports a variety of recording methods, including rich 6K 12-bit RAW short film machine recording, Canon Log 3 which is widely praised and easy to color in cinema EOS film system, high standard HDR PQ, etc., which can meet the different needs of professional video production. In addition, EOS R3 not only supports the standard BT.709 and BT.2020 color gamut, but also supports the cinema color gamut. When used with CINEMA EOS, it can also provide materials with the same tone. The video shot with Canon Log 3 or HDR PQ adopts HEVC coding, supports 10 bit built-in recording and HDMI output, and the color sampling rate is 4:2:2. In addition, when recording MP4 format short films, CFexpress and SD memory cards support dual-card slot simultaneous recording function, and backup can be completed while shooting, even if the memory card fails, don't worry.

When shooting short films, it is the same as when shooting still images. EOS R3 can recognize people's eyes, face, head and body. When detecting animals (dogs, cats, birds), eyes, faces and bodies can be identified, and appropriate focus can be made according to specific conditions. In addition, it can also detect vehicles used for racing. The camera body is equipped with a 5-axis image stabilizer, which can suppress jitter and shoot a stable short film even if there is no OIS in the lens. If an RF lens with an image stabilizer in the lens is used, the jitter can be better reduced by cooperative control. In addition, EOS R3 can shoot short films for a longer time more reliably, and the maximum recording time is 6 hours (at high frame rate, the maximum recording time can reach 1 hour and 30 minutes).

Reliability? Extensibility? network function

EOS R3, as a professional-grade high-speed model of EOS R series, reflects the needs of first-line photographers in the fuselage design. As the first professional model in EOS R series with vertical handle integration, the design fully considers maneuverability and operability, making it smaller and lighter. Without battery and memory card, EOS R3 only weighs about 822g. Compared with the professional model EOS- 1D X Mark III of EOS SLR camera, the weight is reduced by about one third. In terms of fuselage height, this model is about 85% of EOS- 1D X Mark III. In addition, EOS R3 adopts magnesium alloy shell, which has the same dustproof/waterproof performance as EOS- 1D X.

EOS R3, as an integrated model of the grip, is equipped with a rotatable LCD, which supports touch operation. 3.2 High-precision LCD panel of about 4 150000 points, with delicate and high-quality picture, which is convenient for multi-angle shooting. On the basis of EOS traditional ergonomic design, EOS R3 adopts small concave points with good grip, and the design is full of individuality and freshness. Menu, play, delete and other buttons, power switch, still image shooting/short film shooting switch and other operating components, the layout is basically the same as EOS- 1D X series, users can get started quickly. In order to facilitate operation in the dark, the menus and buttons related to playback are backlit. EOS R3 adopts the common large-capacity battery LP-E 19 of EOS- 1D X series, and also supports AC power adapter, USB power supply or charging through USB Type-C terminal, so you don't have to worry about battery life when shooting short films for a long time.
