There were many differences between domestic micro-lenses: ** 1. Price ** 1. ** Low-priced and affordable ** - Some of Yongnuo's lenses were more affordable, such as 35F2, 501.8, 851.8, etc., especially Yongnuo 501.8, which used to be sold for a few hundred yuan. It was a good choice for users with a small budget. - ttArtisan 56mm F1.8 was priced at 867 yuan, which was relatively cheap and guaranteed basic image quality. 2. ** Mid-priced model ** - The 33F1.2 Sniper Series was priced at 1599 yuan. - Some of Vizos 'lenses were in the middle of the price range. For example, the 85mm F1.8Z was priced at 2299 yuan, and the 24mm F1.8 was priced at 2499 yuan. 3. ** Higher Price Type ** - The Meike 851.4 full-frame lens was priced at around 2880 yuan. - The price of the Vizos 75mm 1.2 half-frame lens was 3500 yuan. ** 2. Focus Section ** 1. ** Standard focal length ** - Yongnuo had 35F2, 501.8, 851.8 and other lenses that covered the standard portrait focal length. - Vizos also had 161.8, 241.8, 351.8, 501.8, and 851.8 full-frame lenses that covered mainstream portrait focal lengths. The 231.4, 331.4, 561.4, and 131.4 fixed-focus lenses under the APS-C frame were equivalent to 20, 35, 50, and 85 focal lengths for the full-frame. - The Si Rui Sniper series had lenses that corresponded to the classic focal lengths of 35, 50, and 85. 2. ** Special focal length ** - The Si Rui Sniper series had a 23mm focal length lens, and its full aperture was very shocking. However, this focal length did not have ED lenses, but were all high-refraction lenses. ** 3. Performance ** 1. ** Dispersion Control ** - The Si Rui Sniper series still had room for improvement in controlling the dispersion, but the Meike 851.4 used an ED lens to effectively control the dispersion. - Some of Vizos 'lenses also had good dispersion control capabilities, such as some of its lenses equipped with ED dispersion lenses. 2. ** Automatic Focus Ability ** - Vizos was more successful in autofocus. It had introduced autofocus lenses with multiple portrait focal lengths, such as 161.8, 241.8, 351.8, 501.8, 851.8, etc. - Previously, there were 7 - 8 sub-factory lens brands of Nikon Z-mount, but none of them supported autofocus until Vizos launched the first sub-factory Z-mount lens that supported autofocus. 3. ** Image Quality ** - The 56mm F1.8 of the ttartisan could guarantee the basic picture quality. Some lenses such as 161.8 and 241.8 could also be used to shoot the Milky Way, which had better picture quality. - Judging from MTF, the Vizos Z-mount 24mm F1.8 image quality might not have high expectations. ** 4. Appearance and material ** 1. ** Material ** - Yongnuo's different lens models were made of different materials. For example, the 85mm lens barrel was made of a high molecular material, and the front end of the rubber focusing ring was made of a high molecular material. The 35mm lens barrel was made of an aluminum alloy material, and the 42.5mm lens was made of a high molecular material. 2. ** Exterior design ** - Different brands of lenses had different designs. For example, in terms of the process of the lens logo, the Yongnuo 85mm product information was marked with a gray layer on the lens barrel, while the 35mm lens used the anodisation process and the font was engraved with laser engraving. - There were also opinions that some domestic lenses still had room for improvement in terms of appearance design, such as the shape of the lens and the design of the LOGO. For example, Wei Zhuoshi was suggested to make the lens design more beautiful, and the logo could be re-designed. ** 5. Focus on the picture frame ** 1. ** Full-frame shot ** - Meike 851.4 was a full-frame lens. Yongnuo, Vizos, and other brands also launched full-frame lenses, such as Yongnuo's 35F2, 501.8, 851.8 (there were Sony E-ports and Nikon Z-ports, etc.), and Vizos '161.8, 241.8, 351.8, 501.8, 851.8, etc. 2. ** Half frame shot ** - The 56mm F1.8 of the ttArtisan was a half-frame lens, while the Vizos also had 231.4, 331.4, 561.4, and 131.4 fixed-focus lenses under the APS-C format. Yongnuo also had the 501.8 half-frame lenses with the Sony-mount. Read more exciting novels for free

Promotion of optical lens to related industries

The optical lens had a significant role in promoting many related industries: ** I. Photographic and Video Industry ** 1. ** Image quality improved ** - In the field of photography and video, high-quality optical lenses were the key to producing high-quality images. The optical characteristics of the lens, such as focal length, aperture, angle of view, and aberrations, directly determined the quality of the image. Different types of lenses were suitable for different shooting scenes. For example, wide-angle lenses were suitable for shooting scenery, while telephoto lenses were suitable for close-up or long-distance objects. - For professional film production, advertisement shooting, and photography art creation, high-quality optical lenses could capture more details, make the colors more realistic, and have higher contrast, thereby enhancing the artistic and commercial value of the work. 2. ** Drive technological innovation ** - With the development of optical lens technology, new technologies such as zooming lenses and autofocus lenses made photography and video equipment more convenient and versatile. For example, the appearance of autofocus lenses greatly improved the efficiency and accuracy of shooting, allowing photographers to focus more on composition and creative expression. ** 2. Scientific Research ** 1. ** Microscopic observation ** - In microscopic fields such as cell research, optical lenses were used in microscopes. High-resolution optical lenses could magnify tiny cell structures, allowing scientists to observe microscopic phenomena such as organelle and cell division inside cells. This was crucial for research in biology, medicine, and other disciplines. 2. ** macro observation ** - In the field of astronomical observation, the optical lens in the telescope could collect the light of distant celestial bodies and form an image. Large-caliber, high-precision optical lenses could allow astronomy to observe more distant galaxies, star formation, and other astronomical phenomena, contributing to the development of astronomy. - In materials science research, optical lenses could be used to observe the microscopic structure and surface shape of materials, helping scientists analyze the properties and characteristics of materials and promote the development of new materials. ** 3. Photolocation Industry ** 1. ** Key to chip manufacturing ** - In the field of photolithographic, optical lenses were key components in the manufacture of integrated circuits. Photolocation technology was the key process to transfer circuit patterns onto the chip, and the quality of the optical lens directly affected the performance and reliability of the chip. - High-precision optical lenses could achieve smaller photolithographic resolution, which could produce size and higher-performance chips. This was crucial to the development of the semiconductor industry, such as increasing the computing speed of computer processors and reducing the power consumption of electronic devices. ** 4. Eyewear industry ** 1. ** Vision correction and protection ** - For the glasses industry, the development of optical lenses made the functions of glasses constantly improve. Whether it was short-sightedness, farsightedness, or refraction, suitable optical lenses could accurately correct vision. - At the same time, optical lens technology was also applied to the manufacture of protective glasses such as sunglasses, such as the development of functional lenses such as anti-violet and anti-blue light to provide better protection for people's eyes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
