What's the difference between Nikon z6 and Sony A7M3?

1. Judging the quality of a digital camera depends on the sensor, lens, image processor and control system of the camera. These four elements are the concrete embodiment of camera performance. Of course, the quality of the LCD screen and the material of the fuselage also need attention, but it is not the most important;

2. sensors. Nikon Z6 (hereinafter referred to as Nikon) and Sony A7M3 (hereinafter referred to as Sony) are equipped with the same IMX 4 10 sensor made by Sony, and the BSI quantum efficiency is 64%, but the adjustment between Nikon and Sony is slightly different. According to the evaluation of DXO Mark Lab, the most authoritative third-party sensor evaluation organization in the world (the higher the data, the better), the color depth (color recording ability) is 25.3 bits for Sony and 25 bits for Nikon; The dynamic range (black and white wide range) is 14.7 EV for Sony and14.3 ev for Sony; For Nikon; The available high sensitivity (low light recording ability) is 3730 iso for Sony and 3299 iso for Nikon. Although Sony's running score is slightly better, there is basically no difference in actual imaging. However, it needs to be clear that Sony's dynamic range quality is better in extreme environments. Nikon's exposure is less than 5 files, and there will be horizontal bars when it is pulled back, but Sony will not. On the whole, Sony sensor is better;

3, the lens. Sony's lens group is basically perfect and is still under development. At the same time, Zeiss, Sigma and Longteng are all developing automatic lenses for Sony, while Nikon's lens group is still in the layout, mostly some F 1.8 dog heads. Although the resolution is better, the imaging is not only the resolution, but the original lens Sony won completely. From the point of view of lens rotation, Nikon's rotating ring can only be used by turning its own F-port SLR's G and E lenses, while Sony's rotating ring has many varieties, such as turning its own A-port lens, canon lens and so on. Sony took the lens;

3. Image processor. In terms of image processor technology, Nikon has a deeper background, and the image processing technology Bisogni is a little ahead, which is mainly reflected in the fact that Bisogni, the direct imaging color, is slightly better, and solving its own RAW with its own official software is also a slightly better color for Nikon; But there is no difference when decoding RAW with third-party software (such as PS, LR, C 1, DXO, etc.). ) and the image processor is flat.

4. Control system. The control system involves many items, many of which have camera parameters, so I won't go into details about the parameters, and everyone will know as soon as they are checked. I only pick the most important points. First, the focusing system, Nikon's single focusing accuracy is good in Bisogni, Sony's continuous focusing accuracy is better than Nikon's, and Sony's intelligent auxiliary systems (such as face recognition and eye control focusing, etc.). ) completely defeated Nikon; The second is endurance, Sony beat Nikon; The third is anti-shake performance. Nikon currently only has the fuselage anti-shake. When switching or using the anti-shake lens, you can start the lens anti-shake, and you can't superimpose it. Sony also has fuselage anti-shake, and you can start superimposed anti-shake with the native anti-shake lens. Although Sony's superimposed anti-shake performance is not as good as Oba's, it is better than Nikon's; Fourth, the storage system, Sony uses dual-card storage, Nikon only has a single card slot. Although the performance and stability of XQD card are better than that of SD card, whether it is CF, XQD, SD or any other storage carrier, it is not foolproof, so the insurance factor of dual-card slot is much higher than that of single-card slot; Fifth, continuous shooting performance (strictly speaking, this is one of the performance of image processor), the highest in continuous shooting is Sony/KOOC-0/0 and Nikon/KOOC-0/2, but AF/AE continuous shooting, Sony/KOOC-0/0, Nikon 5.5, Sony is stronger; Sixth, video. Although they are all 4K30P, 1080P 120P, the output of LOG Nikon is 10, and Sony is 8 bits. Video focusing is also better than Nikon, and video Nikon is better. Let's not talk about anything else, such as the viewfinder. LCD screen, Sony is much worse than Nikon; As for the layout of menu logical buttons, although the menu list and sorting of each family are different, the essence is the same, as long as you are familiar with it.

5. To sum up, Sony A7M3 is better than Nikon Z6 on the whole.
