Hello, thank you for your trust, I think D5300 is better.
1. The quality of a digital camera mainly depends on four hard indicators: first, sensor quality, second, lens quality, third, image processing technology, and fourth, control level. These four standards apply to all digital cameras, whether they are dual reflex cameras, SLR cameras, mirrorless cameras (mirrorless cameras) or portable cameras (card cameras);
2. Sensor quality. The three cameras mentioned by the poster are all APSC frame sensors, commonly known as half-frame sensors (compared to full-frame sensors), and their areas are the same (the area of ??the 700D is slightly smaller by one edge, which can be ignored). According to the evaluation by the French DXO mark laboratory, the world's most authoritative third-party sensor evaluation organization, the D5300 has the highest score and the best quality. The results published by DXO are: D5300 has a total score of 83 points, including color depth of 24, dynamic range of 13.9, and usable high sensitivity of 1336; K50's scores are 79 points, with color depth of 23.7, dynamic range of 13, and high sensitivity of 1129; 700D's The results were a total score of 61 points, color depth 21.7, dynamic 11.2, and high sensitivity 681. The D5300 sensor developed by Sony and tuned by Nikon won all the technical indicators. At the same time, the D5300 sensor removes the low-pass filter, making the image sharper. D5300 has the best sensor;
3. Lens quality. Lenses have a huge impact on image quality and are very important. Judging from the quantity and quality of lenses and the support rate of sub-factory lenses, Canon and Nikon are on the same level, and Pentax is slightly weaker. Canon red ring head, Nikon gold ring head and Pentax star head are all very good lenses, but Canon, Nikon and The number and types of lens groups are more powerful, and the heads of cows and dogs are abundant and free. Relatively speaking, for lenses of the same level, Canon's resolution is slightly better, followed by Nikon's. However, due to the drag of the body, Canon's resolution is based on the 12233 resolution standard test and the most authoritative third-party camera comprehensive performance evaluation agency in Germany. According to the evaluation of DP Review laboratory, whether it is RAW format or JPG format, the image quality performance (including resolution) is D5300 first, K50 second, and 700D third;
4. Image processing technology. Canon's patented image processor D chip, Nikon's patented image processor E chip and Pentax Ricoh's patented image processor P chip are generally at the same level, but each has a different focus. Canon pays more attention to noise suppression and portrait processing. Very good, the high-sensitivity is also slightly stronger, but the disadvantage is that the smearing is relatively serious; Nikon pays more attention to detail restoration, and the imaging details are better, but the disadvantage is that the noise suppression of the high-sensitivity is slightly weaker; Pentax pays more attention to color processing, and the so-called Pentax Green is famous in the industry , but the details and high-sensitivity processing are not outstanding. Since the high sensitivity of half-frame SLRs is not a strong point, the advantages of Pentax and Nikon are more important. At the same time, the compression rates of the RAW formats of the three cameras are different. Because SLRs below mid-range do not have TIFF lossless compression format, nor do they have 16-bit RAW format compression, the compression rate of the RAW format is more important. Both the 700D and D5300 It is 14-bit RAW compression, and the K50 is 12-bit RAW compression. Taken together, the D5300's image processing technology is more practical;
5. Control level. The control level of entry-level SLRs is similar, and each has its own strengths. Among them, Canon's focusing technology is more advanced. (For example, although the 700D only has 9 focus points, they are all cross-type for F5.6, and the center is a double focus point for F2.8. Cross-type autofocus), Nikon's configuration is more comprehensive (for example, the D5300 has the spot measurement linkage function only available in Canon's high-end SLRs), and Pentax's body is more generous (for example, the K50 has the pentaprism viewfinder, 1/6000 Shutter, dustproof, waterproof, cold-proof metal frame body, etc.), generally speaking, the highlight of the K50 is the body configuration, the highlight of the D5300 is the point measurement linkage, and the highlight of the 700D is the cross focus point, each has its own use, but there is no way Compare the pros and cons;
6. Comprehensive weighing of the factors of the three cameras, the D5300 has the latest and best sensor, and removes the low-pass filter, resulting in the sharpest image and 39 focus points for more convenient composition. The focus tracking is more powerful, the point measurement linkage is very useful, and it is supported by a powerful NIKKOR lens group and subsidiary lenses. Relatively speaking, the advantages of the D5300 are more practical.
