Choice of camera lensThere were many factors to consider when choosing a camera lens.
If it was shooting scenery, from a novice's point of view, although the wide-angle lens had a large scope and could shoot an imposing manner, there were drawbacks such as small changes in the image and difficult to grasp the perspective relationship. In contrast, the telephoto lens might play a greater role in scenery shooting, and the usage rate was higher. It could also take into account topics such as skits and portraits.
The choice of fixed-focus and zoom lenses depended on the user's needs and the subject. The fixed-focus lens had better image quality and was suitable for portraits with high image quality requirements, which could produce better blurring effects. The zoom lens was easy to use and was suitable for traveling, street sweeping, and other scenes that required flexible shooting of various subjects.
Tianya Mirror was suitable for people who pursued lightness and practicality. It had the characteristics of light weight, wide focal length coverage (from wide-angle to telephoto), and high playability. For example, Tenglong 50 - 400mm, Nikon Z24 - 200mm, Tenglong 50 - 300mm were all good Tianya Mirrors.
For portrait photography, the commonly used focal lengths were 35mm, 50mm, 85mm, and 135mm. From a practical point of view, 50mm and 85mm could be chosen first. The 50mm lens could handle both indoor and outdoor shooting. 85mm was the golden focal length for shooting half-body and close-ups. 35mm was suitable for environmental portraits, and 135mm was suitable for close-ups of people. It could separate people from the background very well.
In terms of movie lenses, the most important feature was the focus effect. After focusing, the focus would not change during the zooming process. This feature was suitable for live broadcasts and other scenes to avoid out of focus.
In addition, lenses with different mounts (such as the EF-mount, the PL mount, the Sony-E mount, etc.) had different prices, performance, and applicable models. It was also necessary to choose a lens based on the actual camera model and other factors.

What are the considerations for lens choice to tell a story in photography?In photography, for story - telling, one key consideration for lens choice is the focal length. A wide - angle lens (e.g., 16 - 35mm for full - frame cameras) can capture more of the scene, which is good for showing context. For example, if you're telling a story about a busy street market, a wide - angle lens can get in all the stalls, people, and the general hustle and bustle.

How does lens choice help to tell a story in filmmaking?The right lens choice can significantly impact how a story is told in filmmaking. For example, a wide - angle lens can show a large expanse, like a whole landscape or a big group of people. This can be used to set the scene, giving the audience a sense of the overall location or the magnitude of an event. It might be used at the beginning of a story to introduce the world where the story takes place.
Canon lens, Nikon lensCanon lenses and Nikon lenses were well-known brands in the field of camera lenses.
In terms of Nikon lenses, the new Z-mount lenses were generally of high quality, such as holo-field compatibility and excellent corner resolution. The F-mount was limited by the caliber and the distance between the two sides, while the Z-mount had a great improvement in this aspect, especially in the wide-angle to mid-focal length section.
Canon lenses, such as the RF28 - 70mm F2.8 lens, had a constant large aperture of F2.8. It was portable, and the image quality was average, even a little beyond the positioning of the silver ring lens. It also had anti-shake function. However, its price was sometimes affected by marketing routines. For example, during the 11/11 period, the price of Canon RF28 - 70mm was higher than the recommended price on the official website and did not return to normal value.
These two lenses had their own optical design features, advantages, and market positioning under different camera mount systems.

What is the lens of the camera lens?Based on context alone
The lens of the camera lens was made up of many different types of lenses. This included a concave lens, which had a thick middle and thin edge structure. It had a converging effect on light, which helped to focus the light on the imaging plane, making the image clear. There were also concave lenses, which were thin in the middle and thick at the edges. They had a diffusing effect on light and were often used to correct aberrations. In addition, there were also aspheric lenses. These lenses were not the traditional spherical shape. They could better correct aberrations, improve image quality, and reduce image distortion and blurring. They were widely used in modern camera lenses.

The camera lens changed to a projection lensSome data showed that the telephoto projection could be used to change the camera lens into a projection lens, and a size image could be projected at a distance of 1.5 meters. He could also use a flashlight as the film's back light and a Nikon lens as the projection lens to make a simple projector and project the reverse film on the wall.

Single lens reflex lens parametersThe angle of view of the medium focal length lens was between 40 degrees and 18 degrees, and the focal length range was between 61mm and 135 mm. The angle of view of a standard/medium-focus lens was about 40 - 55 degrees. In terms of optical characteristics, the photos taken at this focal length had the least distortion and could accurately reflect the shape of the subject. It was also relatively easy to design a large aperture. Different models of medium-focal lenses had different performance parameters in terms of distortion, dispersion, resolution, contrast, and so on. For example, the Olympus OM Zuiko auto-macro 90mm f/2.0 lens had an actual focal length of 90.44mm, an aperture of f/2.04, a pincushion-shaped distortion of 0.47%, and an edge loss of 0.3 stops at f/5.6. Minolta MC Rokkor -85mm f/1.7 lens, the actual test focal length was 85.6mm, with 0.5% barrel distortion, etc.

Canon lens and Nikon lens interface differencesCanon lenses mainly had the lens mount, which was Canon's full-frame single-lens reflex camera mount, as well as the lens mount, such as the ESF-S mount, the ESF-M mount, and the lens mount. Nikon lenses mainly had the lens mount, such as the F-mount, and the Z-mount. Their bayonet types were different, and their size, the distance between the two sides, the number and location of electronic contacts, and other parameters were also different. These differences determined the compatibility between the lens and the body, as well as the realization of functions. For example, Canon's RF-mount and Nikon's Z-mount were large-caliber mounts, but there were still differences in specific size and other characteristics.

Micro-lens flash shows lens errorIf the Nikon micro-display lens was wrong, the document did not mention a specific solution for this display. For Canon 6D cameras, when the lens and camera contact points are faulty, you can try to clean the camera and lens contact points, check the bottom interface of the lens, replace the battery, etc. to solve the problem. If the problem still exists, it is recommended to seek professional repair help. For the case where the SonyMicrophone A6000 couldn't recognize the lens, you could check the instruction manual to check if the lens matched, especially if the automatic function could be used; set the lens-less release shutter in the camera; check if the transfer ring or transfer ring and the camera and lens were installed properly; Clean the metal contact points of the lens. If the problem still exists after cleaning, you need to contact the after-sales service. It is likely to be a problem with the camera or the lens itself. Since you don't know your brand and model, you can refer to the solutions for similar situations mentioned above.
