What aperture is used for a fixed-focus lens to shoot a video?
When a fixed-focus lens was used to shoot a video, different apertures had different effects and applications. When shooting at a large aperture of F/1.8, the edge quality might be a little soft, but the overall sense of blurring and the sharpness of the focal plane were good. After reducing the aperture by one stop, the resolution sharpness was significantly improved, and the blurring of the focal plane was dreamy and delicate. Moreover, when shooting in a backlit environment, the ability to resist ghosts and glare was also excellent. The best picture quality was shot in the aperture range of F/2.8 to F/8. The overall picture quality was very consistent and the color level was rich. However, the problem of dark corners should be paid attention to, but it could be repaired through internal correction. After being affected by the refraction, the aperture quality after F/11 would decline. Read more exciting novels for free

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 big is the aperture of the fixed-focus lens? It's good to take photos
The appropriate aperture size of a fixed-focus lens depends on many factors. Different shooting scenes and needs have appropriate aperture sizes to achieve better shooting results. ** 1. Portrait Shooting ** 1. ** Large aperture (such as f/1.2 - f/1.8)** - In portrait photography, a large aperture could create a shallow depth of field effect, blurring the background and thus accentuating the main character. For example, when an 85mm fixed-focus lens was used to shoot a portrait, the large aperture could simplify the background and highlight the character, and the background blurring effect was better. For example, Canon's RF85mmF1.2L USM lens could produce a soft and beautiful out-of-focus light spot effect under a large aperture. - For 50mm fixed-focus lenses, many had an aperture of f/1.8. This aperture could also produce a certain background blurring effect in portrait shooting. It was suitable for beginners to practice portrait shooting when they had limited funds. 2. ** Medium Aperture (such as f/2 - f/2.8)** - If one wanted to ensure a certain background blurring effect while making the entire character clearer, a medium aperture was a good choice. For example, the Fuji XF35mm F2RQR lens, the F2 aperture could meet daily use in portrait photography, and when paired with some small cameras, the focus was fast and the image quality was better. ** 2. Landscape photography ** 1. ** Small aperture (such as f/8 - f/16)** - In landscape photography, it was usually hoped that the entire picture would be clear. A small aperture could increase the depth of field, allowing the scenery from the front to the back to be clearly captured. The wide-angle lens of the fixed-focus lens was often used for landscape photography. Using a small aperture could better show the details of the entire landscape. - For example, when shooting large scenery scenes or large group photos, a smaller aperture could ensure sufficient depth of field, so that the elements in the entire picture were clearly visible. ** 3. Microscope photography (if the fixed-focus lens has a macro function)** 1. ** Medium to small aperture (such as f/2 - f/8)** - For example, Canon's RF85mm F2 MCROIS STAR lens. When shooting macro shots, the aperture needed to be selected according to the size of the subject and the degree of background blurring. If you want to highlight the details of the macro subject while retaining a certain amount of background information, a medium aperture such as f/2 - f/5.6 is more suitable; if you want the background to be clearer to show the overall environment, you may need to choose a small aperture around f/8. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The most commonly used fixed-focus lens in portrait photography
In portrait photography, 50mm and 85mm fixed-focus lenses were more commonly used. The 50mm fixed-focus lens was suitable for a variety of scenes, such as indoor portrait shooting. Its focal length could cope with most scenes, and it could give the audience a sense of immersion in cultural photography. It could also blur the background to highlight the main body and simplify the composition. It was relatively cost-effective. However, its composition was difficult to impress. The 85mm lens was suitable for portrait shooting in a large environment. The angle of view was about 28 degrees. With a large aperture, the background could be simplified and the character could be highlighted. The background blurring effect was better. The distance from the full-body shot to the close-up was about 1.5 meters to 5 meters, which could maintain a more comfortable shooting distance. The image quality was the ceiling of the image quality of various lenses in many cases. However, its angle of view was fixed. If the shooting distance and angle were not controlled well, the image would lack variation, which would easily lead to aesthetic fatigue. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Nikon 200F2 fixed-focus lens
The Nikon 200mm f/2G ED VR II was a professional portrait fixed-focus lens, also known as the "air cutter." It could handle exciting moments in sports events, but it was best to use a tripod to shoot because the lens was heavy, about 2930g, and the camera weighed more than 4100g.

In terms of performance, before the aperture of F4, the blurring was natural, and the sharpness reached its best when the aperture contracted to F4 - F5.6. The sharpness of F8 began to decline. The anti-shake feature was VR II, which could increase the shutter speed by about four stops. When the anti-shake function was turned on, a relatively clear and sharp image could be obtained regardless of whether it was in Normal mode or Active mode. Its parameters were: the lens weight was about 2930g, the diameter x length (extended from the lens mount) was about 124mm (maximum diameter) x 203.5mm (calculated from the lens mount), the closest focusing distance was 1.9m, and the filter size was 52mm. It was a fast telephoto lens with a shock absorption function of VR II. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
