Hello, thank you for your trust.

1. A6300 and A6500 use the same sensor (both 24-megapixel C-frame IMX284 sensors produced by Sony), the same image processor, the same 425-point phase difference + 169-point contrast hybrid focus system, but the A6500 has more five-axis anti-shake and front-end LSI technology than the A6300;

2. The prices of the A6300 and A6500 are very different. The reason why the A6500 is more expensive is the five-axis anti-shake and front-end LSI technology. LSI technology. The five-axis anti-shake of the A6500 has been evaluated by the German dpreview laboratory, an internationally authoritative evaluation organization, and can reach level 3.5, which means that it can reduce the safety shutter by 3.5 steps (the safety shutter will not be discussed in detail, if you don’t understand it, you can refer to Baidu separately). This is meaningful for shooting static images (such as macro, scenery, still life) under low light, but not for portraits; the front-end LSI technology mainly improves the cache, which is meaningful for continuous shooting and video;

3. Coexisting with the A6300 and A6500, there is now the A6400. The A6400 also uses an IMX284 sensor. The focus system has been upgraded to a hybrid focus system of 425 points of phase difference + 425 points of contrast. The most prominent upgrade is the use of Sony’s flagship A9 The focus calculation has real-time tracking performance, which the A6300 and A6500 do not have, but there is no anti-shake. If you often shoot dynamic subjects (such as sports games, pets) and babies, the A6400 is better than the A6300 and A6500. Shooting sports requires a high-speed shutter, and anti-shake is meaningless. As for the other flip screen angles, etc., I won’t talk about them. You can find them all by searching. I will only talk about the most important ones.

4. The poster has a budget of 2W, which is relatively generous, and you can also choose full frame. First of all, full-frame has better high-sensitivity performance than residual frame. Its advantage is that the sensor has higher pixels at the same pixel density or lower pixel density at the same total number of pixels. The lower the pixel density, the smaller the single pixel. The stronger the photosensitive ability of the photodiode, the better the image. Therefore, the imaging ability of the full frame in low light is better (the high sensitivity is stronger). For example, the half frame is basically over at ISO1600 (ISO3200 is barely usable), while the full frame is still good at ISO6400. Available, while ISO3200 and 6400 are commonly used indoors. Secondly, full-frame has a wider range of lens options;

5. If you only consider half-frame (the advantage of half-frame is that it is lightweight), now is not the time to buy a camera, because Sony will release two models at the end of this month The new half-frame cameras, one of which is entry-level and one is flagship, are speculated to be equipped with a half-frame 32.5-megapixel IMX521 sensor, which is more technically advanced. The performance of its flagship camera may be a combination of 6406500, at least It is also a combination of 6306500, so it is wisest to wait for the new phone to be released;

6. If the waiting time is not allowed, and generally the price of new phones is relatively high and the cost performance is low, if now You have to choose a camera, so if you need to take more photos of babies, I recommend the A6400; if you take more landscapes and macro shots, I recommend the A6500. I personally recommend the A6300, because the A6300 is cost-effective, and its focusing and tracking are sufficient for daily use, including taking pictures of children, but the A6400 is stronger; as for anti-shake, it is not particularly important, anti-shake can only Lowering the safety shutter does not mean that there will be no blur with anti-shake, and the anti-shake of the A6500 is also relatively poor. Of course it is better to have anti-shake, but it is not worth spending nearly double the price to add anti-shake. The saved budget can be used to buy better lenses. As for lens selection, I first recommend the Sigma 56F1.4. This is the best and most cost-effective lens for half-frame portraits. The image quality at half-frame is better than the Soleil 55F1.8 (why does the 55 become worse at half-frame) It’s a long story, so I won’t go into it), and it comes with a 18-135 travel head, which is enough to handle most shooting subjects. As for macro, Sony half-frame does not have a good macro lens. It is recommended to use a close-up lens, which is about 6 times. The close-up lens is also 1:1. This is an excellent alternative to a macro lens. The close-up lens needs to be configured according to different filter sizes. Both the S56 or E18-135 can be used as a macro lens through the close-up lens. The image quality is no different from that of ordinary macro lenses, but there is still a gap between it and high-end macro heads. With this kind of configuration, the budget is more than enough;

7. My recommendations. If you recommend based on a 2W budget, I would recommend the Sony A7M3, which has the second strongest focus performance of current mirrorless cameras (A9 is first), and has stronger focus than the A7R3/4. The 24 million pixels are enough for home use (as long as it is not used for giant cameras). Advertising printing), low pixel density, strong single-pixel photosensitivity, very good image quality, excellent video, and basically nothing to complain about. The recommended lens is FE85F1.8 for portraits and 16-35ZA for landscapes. If the budget for a good macro lens (such as Sony's 90 micro) is insufficient, it is still recommended to use a close-up lens with the FE85 lens. This has a budget of 2W and is a mainstream configuration. Telephoto heads and macro heads can be gradually added in the future, so that they will not be outdated in at least 5 years and can compete in 10 years.

If you often take pictures of food, you can also add a FE28F2 lens, which is compact, cheap and has good image quality, or you can use FE28F2 to replace the 16-35F4. Of course, close-up and macro are two concepts and cannot be confused.
