how to get special analysis zoom lens genshin

Due to the size limitation of the smartphone, it was difficult to set up an optical zoom lens that could be extended outwards. The current solution was to use the main camera focal length of 25mm-28mm as the benchmark, and use a telephoto lens to obtain a disguised " optical zoom " ability. The telephoto lens in the smartphone was not a lens that relied on lens displacement to achieve image zooming in traditional cameras. Instead, it was a " fixed-focus lens " with a focal length ranging from 50mm to 240mm. The relative focal length of the main camera was magnified by 2X -10X. For example, a 50mm focal length telephoto lens could achieve an equivalent 2X optical zoom, and a 240mm focal length lens could achieve an equivalent 10X optical zoom. The optical zoom of a smartphone relied on "switching lenses" to achieve. For example, in the Xiaomi 10 Youth version, different focal lengths were handled by different lenses. When it reached 5X mode, it switched to the periscope telephoto lens for equivalent 5X optical zoom. At other times, different lenses would perform corresponding digital or hybrid zooming. For the periscope telephoto lens, the general 5X telephoto lens needed to adopt a periscope structure, with the LCD sensor and lens arranged horizontally. The periscope lens of some mobile phones had a special design. For example, the periscope telephoto lens of the Huawei P40 Pro+ had three sets of prism. When taking pictures, there were five light path reflections, doubling the focal length and obtaining a 240mm equivalent 10X optical zoom. In addition, there was also a direction for the evolution of the zoom telephoto lens. The 10 lenses in the early ASUS ZenFone Zoom lens module could achieve 1X - 3X true optical zooming through motor displacement;Vivo's APEX2020 concept phone, the internal lens group of the periscope telephoto lens could be moved according to the camera APP interface to achieve 5X - 7.5X continuous optical zooming. The thinnest periscopic continuous zoom module developed by Orphie Light. The lens consists of three groups of " 1GMO6P ", with an aperture of 3.1 - 5.1 and an equivalent focal length of 85mm-170mm. It can achieve 3X -7X continuous optical zoom. The image zooming effect brought by lens displacement is better than digital zoom. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some of the parameters that might be involved in monitoring the power zoom lens: 1. ** Focus Range **: - For example, 10 - 525mm, 10 - 150mm, 10 - 230mm, etc. Different focal lengths determined the zooming ability of the lens and the applicable monitoring distance and viewing angle. For example, the focal length of a telephoto electric lens could range from tens of millimeters to hundreds of millimeters or even higher for long-distance supervision; the focal length of a wide-angle lens was shorter, and the monitoring angle was wider but closer. 2. ** optical zooming factor **: For example, there are 52x and so on. The zooming factor reflects the zooming ability of the lens within the focal length range. 3. ** Pieces **: Some of the lenses are broadcast grade with 2 million pixels. Pieces affect the clarity and image quality of the image. 4. ** Automatic focus function **: Some lenses have an automatic focus function, which helps to quickly obtain clear images at different distances. 5. ** Fog Penetration Function **: It can be used in smoggy weather to improve the visibility of the monitoring screen. 6. ** Day and night function (infrared function)**: Can be used in different lighting conditions during the day and night. It can provide fine black-and-white images at night. 7. ** Automatic temperature compensation function **: To ensure that the lens works normally in different temperature environments. 8. ** Type of serial port communication **: For example, the serial port communication of the USB 485/USB 422 is used to independently control the lens. 9. ** Adaptability to the environment **: Able to work normally from-40 ° C to 70° C, and can adapt to various environmental temperatures. 10. ** Lowest Illumination **: If there is a lens, the minimum illumination is 0.002Lux(color mode), 0.0002Lux(black and white mode), and 0Lux(infrared light on). This parameters reflect the imaging ability of the lens in low-light environments. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many advantages and features to taking photos with a mobile phone and a zoom lens. For example, there was a mobile phone zoom macro lens with a magnifying power of 1.1 - 2.8x, an effective focusing distance of 22 - 82mm, a field of view of 88° at 22mm, and 72° at 82mm. The lens structure was three pieces in two groups, weighing only 24g and was small and portable. This lens solved some of the drawbacks of ordinary macro lenses, such as the difficulty of controlling the shooting distance (ordinary mobile phone macro shooting distance is short, and its effective focusing distance is 22 - 82mm), the depth of field is easy to shoot blurred (it can adjust the depth of field by adjusting the zoom ring, even if there is a deviation in the distance, it can be manually adjusted to become clear), and it can achieve a larger zooming effect (from 1.1x to 2.8x). In addition, some mobile phones came with lenses with different magnifying powers to achieve zooming. For example, the Vivo X60 Pro camera interface, 0.6x was a super wide-angle lens, 1x was the main lens, 2x was a telephoto lens, and 5x was a super telephoto lens. Among them, 0.6, 1x, 2x, and 5x were optical zooming, and other magnifying powers were mostly digital zooming. Different magnifying powers had different image quality, and different brands and models of mobile phone lens had different focal length settings. For example, the three lenses of the iPhone 12 Promax were 0.5, 1, and 2.5 times respectively. The Galaxy Z Flip6 could use the auto-zoom composition function to automatically detect objects through its vertical free shooting system and zoom in or out to take photos with suitable scene composition. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some recommendations for Canon's zooming lens: - Canon RF24 - 105mmF2.8LIS USMZ: This lens can zoom from 24mm to 105mm. The large zoom ratio can be used to shoot different portrait scenes. For example, the 24mm wide-angle end can shoot portraits including the environment, and the 105mm telephoto end can shoot local details. Its constant F2.8 aperture belonged to Canon's red circle L head, which could guarantee the picture quality of photos or videos. The large aperture could provide better blurring performance, which also helped to take high-quality photos when shooting at night. It weighed about 1300 grams and was easy to shoot with a hand. - 24 - 70mm zoom lens: If the budget is sufficient, consider the f/2.8 version. This is a more practical focal length. It can shoot a variety of scenes including portraits such as scenery, flowers, buildings, etc., but the blurring effect is not very good. For example, Canon (Canon EF24 - 70mm f/2.8L II USM) standard zoom lens. - 70 - 200mm focal length: suitable for shooting portraits outside. The telephoto angle is narrow, the image blurring effect is good, and the main body can be highlighted. However, the photographer is far away from the person when shooting, communication is inconvenient, and the lens is heavy. For example, Canon's (Canon EF70 - 200mm f/2.8L II USM) lens belonged to this focal length. - 16 - 35mm lens: It is a wide-angle zoom lens with strong perspective and wide-angle distortion. It can make use of the perspective to make the character more imposing. It can integrate the character and the environment, but it is not suitable for close-up shots. For example, Canon (Canon EF16 - 35mm f/2.8L III USM) wide-angle zoom lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In studio shooting, zooming lenses and fixed-focus lenses had their own advantages. The constant aperture of the fixed-focus lens was generally large, but most of the portraits in the studio were in pursuit of texture. They usually used artificial lighting and a small aperture to shoot, so the advantage of the large aperture of the fixed-focus lens was not obvious here. The zooming lens was more flexible and practical in studio shooting. The size of the studio varied, and the lighting did not change all the time. It was more convenient for the cameraman to use a zoom lens. For example, the common 24mm- 70mmF2.8 or 70mm- 200mmF2.8 zoom lenses were commonly used for indoor studio portraits. In summary, for studio shoots, zooming lenses were relatively more practical, but if you paid more attention to the imaging quality of the lens, fixed-focus lenses also had their value. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
