1. Whether a digital camera is good or not mainly depends on its sensor, lens, image processor and control level;
2. As far as sensors are concerned, after Sony acquired Ke Mei, the overall technical strength of sensor research and development is higher than that of the same industry. For example, Canon, Fuji, Toshiba, Sigma, Panasonic and Belgian New Vision have some differences in the technical strength of Bisogni, but there is no essential difference. The latitude (dynamic range) of Sony sensor is really excellent, but the color reproduction caused by A/D technology is worse than that of Canon sensor and the patented technology of Nikon sensor. Take Panasonic and Sony for example. Although Panasonic has developed 4/3-frame sensors, Sony mainly produces Quan Huafu and half-frame sensors, and there is no comparability between them. However, Sony provided Olympus with a 4/3 format sensor produced by Sony. The quality and quality of the sensor are basically the same as those of Panasonic. Sony has not surpassed Panasonic, and other 1/2.3-inch CCD or CMOS sensors are better than Panasonic.
2. As far as lens is concerned, Panasonic lens and Sony lens belong to the same grade. Sony married Zeiss and Panasonic married Leica, both of which are top optical companies in the world (their lens business only accounts for a small part). Later, Sony developed GM series lenses, and Panasonic developed Songlai L-shaped lenses. Because the image fields of 4/3 lens and Quan Huafu/half-frame lens are different, they are not comparable, but the overall technical ability is of the same level;
3. As far as processors are concerned, Panasonic's Venus image processor and Sony's Bionz image processor are of the same level, which are technically worse than Canon's DIGIC processor, Nikon's EXPEED processor and Pentax's PRIME processor. Among them, Panasonic's processor is lighter in color, and Sony's processor is cooler in color, which is almost the same as a whole.
4. In terms of handling, Panasonic's focusing speed, focusing performance and other handling are good in Bisogni. Panasonic is the originator of fuselage anti-shake. After Sony invested in Olympus, it obtained Oba's five-axis anti-shake basic technology (worse than Oba's latest five-axis anti-shake technology), but Panasonic also obtained Oba's five-axis anti-shake basic technology after cooperating with Oba, and Panasonic is better than Bisogni in both synthetic phase difference focusing and contrast focusing. Panasonic has better control than Sonne, and its mechanical technology is much better than Bisone.
5. Overall, the advantage of Panasonic's main attack on the 4/3 mirrorless camera market lies in the best balance between image quality and portability; On the other hand, Sony mainly focuses on full-frame/half-frame cameras, which have the advantage of higher image quality. Both have their own markets, their own prospects and misplaced development. Therefore, the sentence "Panasonic's products have never surpassed Sony" is completely untrue.
