due to the limitation of space, it can only be simple and may not be comprehensive.
The evaluation criteria of digital cameras (including SLR, single camera, reflex-free and portable) mainly depend on two systems. One is the control system, mainly focusing accuracy, focusing speed, area range, shutter lag, continuous shooting ability, viewing comfort, endurance, resistance to harsh environment (desert, cold, wetland, etc.), body firmness, and so on. The second is imaging system, such as sensor quality, lens quality, image processor technology, etc., in which the sensor accounts for 45% of the image quality, the lens accounts for 5% of the image quality, and the processor accounts for 5% of the image quality. In addition to the appearance of digital cameras, the internal quality is to look at these elements, and the standards are the same. If the image quality is good, it is a high-quality camera, and if the control system is no better, it is a flagship camera. At present, there are 13 mirrorless cameras (micro-single) brands in the market: Hasselblad, Leica, Sony, Canon, Nikon, Fuji, Pentax, Sigma, Samsung, Panasonic, Olympus, Kodak and Xiaomi. Let me briefly talk about the micro-orders of various brands:
1. Hasselblad. There is only one Hasselblad micro-sheet in Sweden, namely Hasselblad X1D, which is equipped with a 51-megapixel medium format CMOS sensor and XCD bayonet developed by Dalsa Company in Canada. This is the best micro-sheet with the best picture quality at present, and none of them are expensive.
2. Leica. Leica's micro-camera is T-series (typ71), which is equipped with a 16-megapixel half-frame CMOS sensor developed by Belgian New Vision Company (CMOSIS). Leica is a luxury in civilian cameras, with the advantage of good image quality, especially excellent color, which is well-known. The disadvantage is that the control is very general, and compared with the expensive price, the control is at most in the middle. Leica also has a small Quan Huafu paraxial camera with interchangeable lenses, which is better than the micro-single, but it does not belong to the micro-single;
3. Sony. Sony micro-single is producing series A, including A7RM2, A7SM2, A7M2 with full pictures, and A65 and A5 with half frames. All sensors developed by Sony are used, and the pixels are different for different models, and the color depth, dynamic range and available high sensitivity are different for different models and technical indicators (the following will not be repeated). Sony is a leader in the research and development of sensors, with leading technical indicators and excellent tolerance (dynamic range), which is proved by the evaluation of DXO Laboratory, the most authoritative third-party sensor evaluation institution in the world. There are many industry-leading technologies in Sony's new micro-sheets, so I won't go into details, but the lenses of Sony's micro-sheets are polarized. The high-end Zeiss lenses and Sony G lenses are very good but expensive, while the low-end lenses are poor and lack of good civilian lenses. Sony micro-single has the advantages of true color reproduction, but the disadvantage is that the automatic white balance is blue and cold, and the portrait skin color is not as pleasing as Canon;
4. Canon. Canon Micro-single EOSM series, currently developed to M5. Canon micro-single is equipped with semi-frame sensors (different models) developed by Canon itself. The advantage is that RGB color separation processing technology is better, but the disadvantage is that the tolerance is not good enough. Although the tolerance of EOSM5 sensor has been greatly improved now, it is still not ahead, which is not right for camera predators. Canon has not put all the latest technologies into new products, and Canon's nickname "Toothpaste Factory" is not groundless. Canon's micro-single has the advantage of better portrait color, and M5' s full-pixel AF focusing technology is also advanced. The disadvantage is that there is a big image quality gap between JPG and RAW, and the direct smearing is more severe, but the RAW compression ratio is 14 bits, which is better than that of other micro-single's 12-bit RAW compression ratio (just not as good as Hasselblad's, but equal to Sony A7RM2). Canon micro-single has fewer original lens groups, and it needs to pass through the adapter ring to use the lens group of Canon SLR.
5. Nikon. Nikon Microcontroller J/V series is equipped with a 1-inch 2-megapixel sensor developed by Aptina Company of the United States. Its advantage is that continuous shooting is very powerful, but its disadvantage is that the sensor area is small. With the popularization of 1-inch sensor card machine, the vitality of Nikon J/V series micro-sheets is limited;
6. Fuji. Fuji micro-single can be divided into high-end XT series and entry-level XA series. It is equipped with X-Trans CMOS sensors developed by Fuji (also equipped with ordinary sensors with different models), and RGB pixels of imitation film are arranged in disorder, so there is no need for low-pass filters, so the resolution is higher. The advantage of Fuji micro-single is that the color is very good, bright and pleasing to the eye, but the disadvantage is that the RAW format also has smearing phenomenon, and the XF lens with better quality is more expensive;
7. Pentax. Pentax micro-single now only has QS series, equipped with a 12-megapixel 1/1.7-inch sensor developed by Sony. The advantage is that the color is better, especially green. The disadvantage is that the sensor area is too small, which is not as good as the card machine. Pentax micro-sheet is the smallest palm micro-sheet, which ranks first in the world as a toy and has no bright spot as a tool;
8. Fit the horse. Sigma Microsystems SDQ series, equipped with X3 sensor patented by Kodak technology Sigma, has two types: half-frame and H-frame. Because the technology of X3 sensor is different from the usual MSK sensor, RGB pixels are superimposed in three layers, so there is no need to guess colors, so it has unparalleled image quality advantages. The image quality of half-frame can be equal to that of medium-frame, and the ART series lens of Sigma is moderate in price and good in quality, which can compete with top-class lenses such as Zeiss and Leica. The disadvantage of Sigma micro-single is that it must use RAW format to reflect the amazing image quality, which is demanding for the later stage, troublesome, and poor in low-light imaging.
9. Samsung. Samsung micro-single NX series is equipped with semi-frame sensors (different models) developed by Samsung itself. The technical indicators of evaluating Samsung sensors by French DXO are also very good, and the image quality does not need other micro-single differences, but it does not have its own characteristics and highlights, especially Samsung's quality control needs to be improved. Samsung's own lens is very poor, and the high-end German Snyder lens is very expensive;
1. Panasonic. Panasonic micro-single has GH, G, GX, GF series, etc. It is equipped with 4/3-inch sensors (different models) developed by itself. The high-end GH series is the best camera to shoot video, and there is no one. The advantage of Panasonic micro-single is that it focuses quickly, but the disadvantage is that the straight color is not leading. Although Panasonic's color has made rapid progress recently, compared with other manufacturers, color still has no advantage; The biggest advantage of the 4/3 system micro-single is that it achieves the best balance between image quality and portability, and the lens group supports strongly. It is particularly worth mentioning that Panasonic's quality control is very good, and there are few quality problems;
11. Oba. Oba micro-single has three categories: EM, EPL and EPM series, as well as retro PEN-F, etc. It is equipped with 4/3-inch sensors (different models) developed by Sony (and some Panasonic). The advantage is that the high-end five-axis anti-shake of the fuselage is leading in the industry, which is very powerful. Oba's five-axis anti-shake has been imitated and never surpassed. As a member of the 4/3 system, Oba has the same advantages as Panasonic, but the disadvantage is that the automatic white balance has never been accurate, and it is red. Once the warm color switch in the machine is turned off, the warm color is not warm;
12. Kodak. Kodak micro-single S1 is equipped with a 4/3-inch 16-megapixel sensor developed by Sony, and enjoys 4/3 bayonet lenses such as Panasonic and Oba. Due to the massive loss of old Kodak's technicians, Kodak is not the Kodak of the past, and Kodak micro-orders have no special highlights except the brand effect left by Kodak.
13. Xiaomi. Xiaomi micro-ant, equipped with a 4/3 inch 2 megapixel sensor developed by Sony, * * * enjoys 4/3 bayonet lenses such as Panasonic and Oba. The highlight of Xiaomi's micro-order is the only domestic brand at present. If domestic products are to be supported, let alone shortcomings.
