Hello, teacher, I would like to ask about the purchase of digital DC.

1. At present, portable digital cameras (DC) with a budget of about 4,000 yuan on the market mainly include Canon G 1XM2, G7XM2 (G5X, G9X, etc. ), Sony RX 100M3, Panasonic LX 100, LX 10, ZS 65438. Excluding Sony RX 1M2, Leica q, Leica x, RX 100M5, etc. Which ones are more expensive, not including Nikon CA and so on. , has been discontinued; Not counting Sony RX 10M3, Canon G3X and other large bridge machines (telephoto machines). And not counting a lot of 1/2.3-inch DC that will be replaced by mobile phones. Let me talk about the advantages and disadvantages of these cameras for your reference.

2. Ricoh GR2. In digital imaging, the outsole is king, that is to say, under the premise of using the same quality lens, the larger the sensor area, the better the imaging quality. GR2 is equipped with a16 megapixel sensor developed by Sony, and adopts a fixed-focus lens with a maximum aperture of F2.8 equivalent to 28 (the same camera angle of a mobile phone in apsc). GR2 is the second best DC with 4000 budget (the first is Hummer), and the control (such as focusing speed) is the first. It is very portable (pocket computer). However, GR2 has two problems. First, the straight color is not good enough, and there is an obvious orange tendency. Some people say that it is similar to the photo style of the 1980s, and many people don't like it. It is troublesome to shoot in RAW format and correct the color after retouching. Second, the use of fixed-focus lens, can not zoom, travel is not convenient enough (whether the problem varies from person to person). In addition, GR2 doesn't have a flip screen, so it's not convenient to shoot high and low positions, which is a problem for some people, but not for some people, so I won't go into details here.

3. Fuji X70. The X70 is equipped with the second generation X-Trans sensor developed by Fuji, with a half frame of 6.5438+0.6 million pixels. It adopts a pixel array with silver salt particles arranged in disorder like film, and there is no low-pass filter, so the resolution is relatively high. Although the parameters of X70 lens are the same as GR2 (both are equivalent to the maximum aperture of 28 F2.8), the resolution of the lens is not as high as GR2, so the image quality is slightly worse than GR2. The X70 has the advantages of Fuji's exclusive film mode, eye-catching color, no need for post-production, flip screen, good control and high value, but it is also a fixed-focus lens, which is not convenient enough.

4. Sigma ·DPQ series. DPQ series can be divided into DP0Q, DP 1Q, DP2Q and DP3Q (all fixed-focus lenses with maximum aperture F2.8) according to different lens angles, and equipped with X3 sensor patented by Kodak technology. (At present, digital sensors are divided into three categories: one is the common MSK sensor, which uses RGB color separation processing, including direct-down, back-illuminated, stacked and so on; Second, Fuji exclusive X-Trans sensor, RGB array processing; Thirdly, Sigma's exclusive X3 sensor uses RGB superposition processing, each with its own advantages and disadvantages). When the light is good, the image quality is extremely high, which is no better than that of high-end Quan Huafu. However, the image quality is very poor in low light, so it is difficult to shoot by hand without tripod at night (definitely paste) and the control is also very general. In particular, DP series must be shot in RAW format and retouched with Sigma's royal software SPP to reflect the amazing image quality of Sigma camera.

5. Panasonic LX 100. LX 100 is equipped with16 megapixel sensor, with an area of 1.2 inch, which is cut by16 megapixel 4/3 sensor developed by Panasonic, and adopts Songlai (made by Panasonic and certified by Leica Technology) lens, with the maximum aperture of f/KLOC-0. The advantage of LX 100 is that the signal-to-noise ratio technology of the sensor is very good, with low pixels per inch and very pure image quality. The disadvantage is that Panasonic's direct color is relatively light, and its visual comfort is not good enough, which requires some post-processing.

6. Sony RX 100M3 and Canon G7XM2 (both Canon G5X and G9X are versions evolved from G7X, not as good as G7X) are equipped with a sensor with 20 megapixels 1 inch developed by Sony (whether Canon uses this sensor from Sony is controversial). Sony adopts Socai lens with equivalent maximum aperture of 24-70 F 1.8-2.8, and Canon adopts EF lens with equivalent maximum aperture of 24- 100 F 1.8-2.8. The difference between the two machines is that Socai lens has better quality, higher definition, better film definition, longer Canon focal length and more convenient use. Moreover, Canon has unique skills in dealing with portrait skin color, and the portrait effect is better than Bisigny. In addition, RX 100M3 adopts Zeiss standard lens, which is the best zoom lens in DC at present. Without competitors, including Panasonic's Sonlai lens, the price is always firm because of cost and other reasons.

7. Panasonic LX 10 and ZS 1 10. LX 10 and ZS 1 10 are equipped with a 20 megapixel 1 inch sensor developed by Panasonic. LX 10 adopts a loose lens with an equivalent maximum aperture of 24-72 F 1.4-2.8, and ZS 1 10. The image quality of LX 10D is much better than that of ZS 1 10, and is basically the same as that of RX 100M3 and G7XM2, but the direct colors of Bisogni and Canon are slightly weaker. As for the aperture of F 1.4, the depth of field is blurred because there is only a 1 inch sensor. ZS 1 10 Although the picture quality is poor, it is equipped with a lens with optical zoom capability of 10, which is convenient for a mirror to travel all over the world.

8. Canon G 1XM2. G 1XM2 is a 1.5-inch12-megapixel sensor cut from a18-megapixel half-frame sensor developed by Canon. Equipped with EF lens, the maximum aperture is F2-3.9. The size of the sensor is close to that of a half-frame sensor, with a large aperture of F2, and the background blur ability is very good. However, because Canon's18 megapixel sensor is the technology of 10 years ago, it has shown poor fatigue and tolerance, especially poor highlight performance, which often appears in real shots, and the imaging quality is not very good. Fuji X30 is equipped with a 2/3 inch sensor, so the area is relatively small and the picture quality is not very good.

9. To sum up, if you are interested in the later stage and are used to shooting slowly, I recommend Sigma DPQ series; If you are interested in post-production, you often need to take snapshots or night shots, and Ricoh GR2 is recommended; If you are not interested in the later stage and don't care about the inconvenience of focusing, Fuji X70 is recommended. If it is easy to use, Sony RX 100M3 is recommended with landscape as the main map, and Canon G7XM2； is recommended with portrait as the main map. If you want to catch something and shoot something, taking shooting as the first element, we recommend Panasonic ZS 1 10. Personally recommend Sony RX 100M3, considering the film clarity, ease of use, portability and other factors.
