High image quality, comprehensive performance, Sony, Canon and Nikon's main full-frame mirrorless cameras

For photography enthusiasts with high requirements, a full-frame mirrorless camera is undoubtedly one of the most suitable equipment. In particular, the main models of Canon, Sony, and Nikon not only have high-quality output performance, but also have excellent performance in video shooting, focusing function, continuous shooting performance, and anti-shake performance. They can be described as all-round models. Moreover, the prices of these main models are relatively not too high, and many people can afford them. Today we will recommend to you the main full-frame mirrorless camera among the three photographers.

Sony full-frame mirrorless A7M4

The Sony A7M4 is equipped with a full-frame back-illuminated Exmor CMOS image sensor of about 33 million pixels. Compared with the 24.2 million pixels of the A7M3, it has been significantly improved. The high pixels bring The finer picture details also have obvious advantages compared with other models in the same position and price range. The new sensor also brings a sensitivity range that can be expanded to ISO50-204800 (A7M3 is ISO 100-51200), and has a 15-stop dynamic range at low sensitivity, allowing users to operate in complex light environments. Improve shooting success rate.

Sony A7M4 uses 7K supersampling for 4K 30P recording in full-frame mode, allowing you to obtain high-resolution, high-detail 4K video. The 10-bit color depth and 4:2:2 color sampling make the video color changes smoother and more natural, and also provide greater convenience for post-processing. Anti-shake enhancement mode can help users obtain stable images when shooting handheld.

Sony A7M4’s five-axis anti-shake system can achieve up to 5.5 levels of anti-shake effect, and you can get clear and sharp images when shooting handheld in low-light environments.

The A7M4’s continuous shooting speed is 10 frames/second. Although it is not too fast from today’s perspective, it is enough when facing most high-speed sports scenes. When shooting sports and ecological photography, this continuous shooting performance gives users the right to freeze wonderful moments. More importantly, the A7M4’s continuous shooting endurance is excellent. When using uncompressed RAW+JPEG, it can achieve a continuous shooting performance of about 828 shots, and when using compressed RAW+JPEG, it exceeds 1,000 shots. (Using CFexprsee Type-A memory card)

Sony A7M4’s 759 phase detection focus points, focal plane phase detection focus system covering approximately 94% of the frame range. It supports real-time tracking of human eyes when taking photos and videos, and the face and eye detection accuracy is improved by about 30% compared to the previous generation product. In addition to human eye detection, the A7M4’s real-time eye focusing function can also detect and focus on the eyes of animals, especially birds. The BIONZ XR image processor provides excellent autofocus performance, enabling AF/AE tracking and calculation during high-speed continuous shooting of the A7M4. The large cache on the body will provide users with a smooth shooting experience.

Canon full-frame mirrorless EOS R6 Mark II

Canon EOS R6 Mark II is a full-frame professional mirrorless camera with very powerful performance. It has satisfactory performance in still photos, dynamic videos, as well as focusing, continuous shooting, anti-shake, etc. It is a product that is very popular among photography enthusiasts.

Canon EOS R6 II is equipped with a 24.2 million effective pixel full-frame CMOS sensor. When working with the DIGIC X image processor using a new image algorithm, the picture resolution is comparable to Canon's 30.4 million pixel DSLR camera EOS 5D Mark IV. In addition to its excellent detail performance, the Canon EOS R6 II's high-sensitivity shooting performance is also very good. Even in extreme shooting situations such as starry sky photography with low light, high sensitivity, and long exposure, it can output photos with pure images and rich details.

EOS R6 II supports a variety of short film recording formats including 6K super-sampled full-frame without cropping 4K 59.94P/50.00P short films; Full HD 179.82P/150.00P high frame rate. It also supports recording HDR clips based on 4:2:2 10bit HDR PQ and 4:2:2 10bit Canon Log 3.

Canon EOS R6 II is equipped with the second-generation full-pixel dual-core CMOS AF focusing system, which can identify people and animals in the picture and many subjects including cars, trains, airplanes, etc. The camera can focus easily at -6.5EV and can shoot in dim scenes.

EOS R6 II’s five-axis anti-shake body and RF lens anti-shake system can achieve an 8-level shake supplement effect. You can also get clear and sharp images when shooting night scenes handheld. The EOS R6 II also features digital image stabilization for short movies. When shooting video with a lens without anti-shake function, the body's 5-axis anti-shake can work together with the short-video digital anti-shake to suppress shake and stabilize the picture.

Under the electronic shutter, the EOS R6 II's continuous shooting can reach up to 40 frames/second (auto focus/auto exposure tracking). In the RAW continuous shooting mode, the EOS R6 II also has a "pre-shooting" function, and the camera can automatically The image is recorded up to approximately 0.5 seconds before the shutter is released.

Nikon Z6 III

The effective pixels of Nikon Z6III are 24.5 million, and it also supports pixel shift shooting function, which can achieve higher resolution performance. The Nikon Z6III is the first model in Nikon history to feature a partially stacked sensor that integrates high-speed processing circuitry above and below the imaging unit. The benefit of this is that the Z6III's data reading speed is about 3.5 times faster than the Z6II. Therefore, it can not only bring higher specifications of video performance, but also make a qualitative leap in continuous shooting speed.

The continuous shooting speed is 14 frames/second (RAW format) under the mechanical shutter, and 20 frames/second (RAW format) under the electronic shutter. In the non-cropped JPEG format, the high-speed continuous shooting has increased to 60 frames/second. In the DX format JPEG format, the high-speed continuous shooting has reached 120 frames/second, and the Nikon Z6III also has a one-second pre-shooting function, which is Can record the picture one second before the shutter is released. The increase in continuous shooting speed allows the Z6III to better record wonderful moments when facing sports and ecological photography.

Video is the key area of ​​improvement for Z6III. A simple summary is that it supports high-standard videos such as 6K/60P N-RAW, 6K/30p ProRes Raw, 4K/120p (DX). It can also record 4K 120P (1.5x crop) high frame rate video in H/265 specification, and FHD 240P high frame rate video. At the same time, officials said that the single recording time of 4K 60P is up to 125 minutes.

Z6III borrows the object detection technology of Z9 and Z8 and can detect and track 9 types of subjects, including people (face, eyes, head and upper body), dogs, cats, birds, cars, motorcycles, Bikes, planes and trains. Object Detection "Auto" causes the camera to detect these 9 types of objects within the frame without having to switch object types in the menu. You can track these subjects using 3D Tracking, Auto-area AF, Wide-area AF, and Subject-Tracking AF. Custom Wide-Area AF also detects and tracks subjects within a designated area.

Z6III has in-body anti-shake function, which can provide up to 8 levels of anti-shake effect. This performance also exceeds that of the higher-level Z9 and Z8.
