How to Choose Sony a7m3 and a7m2 —— Comparative Evaluation of Sony a7m3 and a7m2

Sony's A7 series micro-camera is very popular among photographers. After Sony officially released the third generation A7 series A7M3, many friends are struggling to choose which one. Sony a7m3 or a7m2, which is more cost-effective? This paper mainly introduces lens compatibility, focusing performance and shooting function one by one. Come and find out!

1. Differences in compatibility between Sony a7m3 and a7m2 lenses a7m3 supports carrying a variety of lenses, among which carl zeiss lens has the strongest compatibility. Compatible with Zeiss lens with ED, IF and OSS functions. Other brands of lenses are supported as long as they meet the E or F bayonet, but the performance compatibility cannot be maximized. A7m2 supports all brands and full range of E-mount lenses, and the camera supports jumper compatible with A-mount lenses. A7m2 can give full play to its best performance, and the compatible lenses are mainly medium-long focal length lenses.

2. The difference of focusing performance between Sony a7m3 and a7m2. Both a7m3 and a7m2 adopt the phase detection autofocus function. The former has 693 phase detection focuses and 425 contrast detection focuses, and autofocus can basically cover 93% of the lens' entry range. The latter has 1 17 focal points for phase detection and 25 focal points for contrast detection. Because a7m2 adopts hybrid autofocus, its focus coverage only accounts for 45%~48% of the lens entrance range, and the specific coverage depends on the real-time growth performance of the imager.

3. The difference between Sony a7m3 and a7m2 navigation keys a7m3 uses a large number of navigation keys, that is, the function keys for setting camera parameters with one button, which can save users the trouble of complicated parameter setting when dealing with different shooting environments. Although a7m2 also has the function of navigation key, its setting parameters are not automatically determined by the system. Its navigation keys can only set basic parameters, and important parameters such as real-time ISO, white balance and zoom need to be set manually by users themselves.

4. In terms of image quality, A7M3 is still equipped with a 24.2 megapixel Quan Huafu sensor, ISO support can be extended to 50-204800, and the dynamic range is as wide as 15. At the same time, Sony also upgraded the new 5-axis anti-shake function, which can provide the anti-shake effect of 5-speed shutter and also support the output of 14bit RAW files. Continuous shooting can also use 14bit RAW!

5. Sony camera recommendation 1 and Sony DSC-RX 100M5A.

Reference price: 5499 yuan

Lens performance: this Sony camera is equipped with a short-focus lens with an adjustable aperture of 8.8~25.7mm from f/1.8 to f/2.8. The lens has ISO optical anti-shake function, and the lens is designed with aspheric lens and carbon dioxide optical coating. The lens has excellent waterproof and dustproof performance, and also has excellent light compensation ability.

2. Sony ILCE-6000L

Reference price: 3649 yuan

Shooting effect: Sony's camera is equipped with a CMOS sensor with 24.3 effective pixels. Its imaging can achieve 4KUHD full HD, with fine details and high color saturation. If the camera's HDR shooting function is turned on, its shooting will also have lower picture noise and more realistic color effect.

6. Otherwise, the continuous shooting speed of A7M3 is about 10 frame/second, which can be achieved by both electronic shutter and mechanical shutter. In terms of continuous shooting, JPEG format can reach 177 frames at most, while uncompressed RAW format continuous shooting can reach 40 frames. In addition, the 4K video shooting function is also not available in the second generation products.

Generally speaking, compared with M2, A7M3 has greatly improved in video performance, focusing performance, battery life and storage, and the part based on image quality has not changed much. Therefore, M3 is more for people with professional needs, and if you only shoot at the entry-level level everyday, the experience improvement brought by A7M3 may only be obviously reflected in battery life.

And some friends may still struggle between A7R2, A7S2 and A7M3. After all, their prices are all around 15000, not to mention the S series. 12.2 megapixel sensor, only night shooters and video players will consider it.

Generally speaking, it is difficult to choose between R2 and M3. One is better battery life, continuous shooting and focus, and the other is better picture quality. Finally, as a user of A7M2, I can only say that if you are not a Maoist, a more balanced Sony A7M3 would be a better choice. After all, the Quan Huafu with 24.2 million pixels is already very strong, so the Scenery Party and the Mao Party should choose Sony A7R2 camera.
