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>

The bigger the focal length of the phone lens, the better
This statement was not accurate. Different focal lengths had different uses in mobile photography, and each had its own advantages. It was not easy to think that the larger the focal length, the better. In mobile phone lenses, smaller focal lengths such as super wide-angle lenses (usually 18 - 24mm range) had a wide field of view and were suitable for shooting large scenes, such as city panoramic views, beaches, mountains, and other large scenes. They could also use their exaggerated perspective effects for creative photography. The wide-angle lens (between 24 - 35mm) was often hailed as a "master lens" in the industry. It was suitable for landscape photography and architectural photography. It could accommodate more scenes and was suitable for large depth of field, so that the background and the background could be clearly presented. In terms of medium focal length, the standard lens (50mm equivalent focal length) was suitable for daily shooting and street shooting. The angle of view was naturally close to the image seen by the human eye, and it was very versatile. In terms of telephoto lenses, short telephoto lenses (85 - 135mm) and medium telephoto lenses (135 - 300mm) could produce background blurring effects in portrait photography to highlight the subject. They were also suitable for scenes that required long-distance shooting such as wild animal photography and sports photography. However, telephoto lenses were not necessarily better with larger focal lengths, because larger focal lengths could mean larger lens size and higher cost. It was also more likely to cause problems such as blurred images due to hand shake when shooting. In addition, the main camera lens (usually 25 - 28mm) had better quality optimization and was commonly used in most shooting modes of mobile phones. Therefore, different focal length lenses had their value. It depended on the needs of the photographer and the shooting scene. The larger the focal length, the better. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to zoom the lens
The SonyE18 - 200mm f/3.5 - 6.3OSS (SEL18200) lens was an E-mount high-magnification zoom lens. It was designed with an internal structure to achieve a zoom of 18mm-200mm (35mm equivalent focal length 27mm-300mm). The lens may be equipped with a zoom ring. By rotating the zoom ring to change the focal length, the lens's zooming function can be achieved. However, the reference materials did not give more information about its specific zooming operation. <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>

Mobile phone shooting rotation lens tutorial video collection
Here are some tips for shooting a rotating camera with a mobile phone: ** 1. Basic Rotation Shot ** 1. ** The rotating camera shooting technique in the example of shooting the rotating flower sea ** - ** Setting of parameters ** - He turned on the phone's professional mode and set the shutter speed to about 1/20 of a second. This way, he could capture the continuous motion of objects when he rotated the phone, such as the effect of a flower spinning. He chose 100 for an even clearer picture and less noise, and set the white balance to 6000K (suitable for blurry scenes, but can also be adjusted according to the actual subject). - ** Shooting Points ** - Focus: Focus on the center of the screen and aim at the subject you want to shoot. This subject can be a flower or a cluster of flowers. - ** Rotation Operation **: With the center of the phone lens as the center, press the camera button and rotate the phone quickly. - ** Body Condition **: Relax your body when shooting. It's easier to get the ideal effect by turning it slightly. 2. **360-degree rotation shooting technique ** - [Holding method and preliminary rotation: Turn your thumb up and rotate it 180 degrees.] - ** Setting up the camera and further operation **: Turn the phone to 0.5x super wide angle, rotate it 180 degrees, find a good angle, and then slowly push forward and rotate it slowly to complete the 360-degree rotation shot. ** 2. Rotation of the special mirror ** 1. ** Rotation related camera movement in the camera movement diagram ** - For example, rotation + push forward, rotation + pull back + drop, semi-surround, and other rotation operations in the lens operation mode could be added to the push forward, pull back, drop, or semi-surround movements according to the actual scene and effect. This would increase the dynamic sense and visual effect of the picture. 2. ** Rotation related to the camera reversal shot (from the feet to the back)** - When shooting in the front passenger seat, he turned on the rear camera's 0.5x wide-angle mode. He first took a photo of his feet, then turned the phone over to take a photo of his back. After that, the video was imported for post-processing. The curve speed was changed. Points were added at the back of the camera and the back of the camera. The part of the camera facing the back was accelerated to about 1.7 times, and the other parts were accelerated to 0.1 times. The smart frame was selected to achieve a special visual effect. The phone flipping was also a special rotation operation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
