The bigger the lens zoom, the better? Video tutorial
The larger the zooming factor of the lens, the larger the focal area of the wide-angle end and the telephoto end, and the more diverse the usage methods. For example, during shooting, the shooting range could be freely changed without moving the position. The wide-angle end could expand the shooting range, and the telephoto end could enlarge the subject. However, a camera with a large zoom factor might become larger due to its structure, making it inconvenient to carry. Moreover, in some devices, if the zoom ratio was increased through digital zooming (for example, when some cameras used digital zooming), the camera's overall picture information would be partially cut and shot, which would result in a reduction in resolution (the density of the image). For example, for a camera with 8MP, the digital zoom was 2x (when the optical zoom was 4x, it would display "8x"), and the number of the actual number of the actual number of the total number of the total number of the actual number of the number of the total number of the number of the Therefore, the larger the zoom factor of the lens, the better it was. It was necessary to determine the appropriate zoom factor according to the actual shooting requirements, such as the balance of factors such as maneuverability, image quality, shooting range, and so on.

Is it better to have a bigger zoom ratio?
The larger the zoom ratio, the better. In terms of image quality, the lens with a large zoom ratio covered a wide focal length and did not take into account the optical quality. For example, the big three-dimensional lens was more expensive, but the zoom ratio was not large, which was to better protect the image quality. From an aperture perspective, the aperture of a large zoom lens was almost floating, and the maximum aperture changed greatly at different focal lengths. For example, there might be a larger aperture value at the wide-angle end, such as f3.5, but after adjusting the focal length, the aperture would be greatly reduced. In the telephoto section, it might only be f6.3 or smaller, which limited the role of the lens and limited the creative space. In terms of volume and weight, although the large zoom lens seemed to be an advantage in terms of volume and weight, it was exchanged for the sacrifice of key indicators. For example, the quality of the lens was not high enough, which affected the image quality. The anti-shake function was poor or non-existent. Hand-held shooting was restricted. The workmanship was relatively basic, and the lens body was mostly made of plastic. However, in some special situations, a large zoom lens also had its advantages. For example, for some travel scenes, such as college students 'trips, the large zoom lens was easy to carry and would not cause a burden due to carrying a variety of equipment. Moreover, some large zoom lenses now had good performance in terms of image quality, anti-shake, focusing, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is it better to use a fixed focus lens or a zoom lens for a novice lens?
For beginners, a zoom lens might be better. From the perspective of operational convenience, the focal length of the zoom lens could be adjusted within a certain range. For example, the common 20 - 70mm lens could be used to change the choice of shooting "far" and "close" by twisting the zoom ring. It was more convenient when shooting scenes such as cultural activities, tourism, scenery, animal activities, etc. The focal length of the fixed-focus lens was fixed, and the composition of the picture was relatively fixed. To achieve a change in the picture, the photographer could only move forward and backward to adjust the position. This was more troublesome in many scenes, such as macro shooting or shooting in the wild. It might be very inconvenient to move the position. Considering the growth stage, newcomers were generally in the initial growth stage of photography. The zoom lens had many conveniences and could be adjusted. It was more suitable for beginners to explore different shooting scenes and objects and accumulate shooting experience. When the photographer had accumulated a certain amount of shooting experience, entered a certain "level", and had his own unique control over the composition and framing, and the subject matter was relatively concentrated, he could consider using a fixed-focus lens to enhance his shooting. However, if a novice had high requirements for image quality and didn't mind adjusting the image by moving the position, a fixed-focus lens could also be chosen because the image quality of a fixed-focus lens was usually better than a zoom lens at the same price. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It's better to use a zoom lens or a fixed-focus lens for the studio shoot
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>
How to make a lens magnifying glass video tutorial
The following is a method of making a lens magnifying glass: 1. [Material preparation: A computer camera with a rotating lens is required.] 2. Operation steps: - He plugged the camera into the computer and turned on the computer's built-in Ecap (Win7 system only, if the computer did not have it, it could be downloaded). - He rotated the camera in one direction and placed the tip of a ballpoint pen close to the camera. - If a clear image of the pen tip could be seen from a certain distance, it would be turned in that direction a few times. In this way, it would be made into a super-magnifying glass. - If he couldn't see a clear image of the tip of the pen at any distance, it meant that he had turned it in the opposite direction. He would try turning it in another direction. There was also a self-made magnifying glass (not a lens magnifying glass but a reference): 1. [Material preparation: Find a small-caliber concave lens (like the one on a microscope lens), a gel pen cap (made of plastic), and take a small section.] 2. Operation steps: Embed the concave lens into the plastic tube. However, this was not the content of the video tutorial on how to make a magnifying glass. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Smart phone zoom lens
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>
Monitor the parameters of the electric zoom lens
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>
