The camera lens is expensive
In the field of photography, expensive lenses had their value. Generally speaking, more expensive lenses had higher performance in terms of optical quality, workmanship, and performance. For example, in the field of medium and long focal length lenses, Canon's RF70 - 200mm f/2.8L IS USM was priced at 16999 yuan, and the Sony70 - 200mm F2.8GM OSS II was priced at 18999 yuan. These lenses were expensive, but they could provide better imaging results, excellent focusing performance, and good durability on their respective cameras. However, with the changes in the photography market, the relationship between price and value did not completely follow the traditional principle of "you get what you pay". In the micro-monocle era, although some high-end lenses had improvements such as quieter focusing, better design, and improved electronic functions, compared to similar lenses in the DSLR era, users felt less about the improvement in optical quality, but the price generally rose. Some of the affordable entry-level lenses, such as the 50mm f1.8 lens, were no longer as affordable as before. Branded lenses of this size were even hyped up to three times the release price. 24 - 105mm f4 or similar lenses were nearly twice as expensive in the micro-single era as in the single-lens reflex era. Although the optical quality had improved, there was no particularly huge breakthrough. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Is there a difference in the size of the surveillance camera lens
There was a difference in the size of the surveillance cameras. Different sized lenses had different viewing angles and distances. Generally speaking, the smaller the millimeter of the lens, the larger the angle of the surveillance picture, but the clearer the distance. On the contrary, the larger the millimeter of the lens, the smaller the angle of the surveillance picture, and the clearer the distance. For example, the 2.8mm focal length lens has a large viewing angle, suitable for monitoring small spaces such as storage rooms within 3 meters; 4mm can be used for indoor environments such as living rooms and small shops; 6mm is suitable for small shops or doorways of 5 - 10m; 8mm is best for outdoor roads and alleys of 10 - 20m; 12mm is mainly used for specific locations such as entrances and exits of about 20 - 30m. In addition, from the relationship between angle and distance, the larger the angle, the closer the distance. For example, the 3.6mm lens was 67.4 degrees, and the distance was 15 meters; the 6mm lens was 42.3 degrees, and the distance was 20 meters; the 8mm lens was 32.6 degrees, and the distance was 25 meters; the 12mm lens was 22.1 degrees, and the distance was 40 meters; and the 16mm lens was 17.1 degrees, and the distance was 60 meters. The common surveillance camera lenses on the market were arranged according to the size of the frame: 2.8mm, 3.6mm, 4mm, 6mm, 8mm, 12mm, 16mm, 24mm, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
