How about putting a wide-angle lens on the phone lens?There were many advantages to installing a wide-angle lens on a phone lens.
From the perspective of the shooting effect, the wide-angle lens could expand the field of view of the camera, making the captured picture wider and grander. For example, it could cover more scenery elements when shooting scenery, and it could also shoot a larger and richer scene in a narrow space. In terms of portrait photography, it could make the person look thinner and more beautiful, and it could also expand the front and back scenes, allowing the picture to accommodate more content. For example, the situation where the feet could not be seen when taking a full-body photo could be improved.
In terms of functions, some wide-angle lenses also had a macro function, which could be used to shoot close-up shots and other images with different needs. Some wide-angle lenses also had a fill light, which could provide lighting assistance in the case of insufficient light. Some even had the function of live beauty fill light, cold and warm seven-color dimming, which could help improve the image effect in live broadcasts and video shooting scenes.
However, there may be some minor problems with installing a wide-angle lens. For example, it may affect the image quality of the original lens of the phone, and the effect of wide-angle lenses of different quality and price may vary greatly.

Do you need a super wide-angle lens for daily shooting?Whether or not an ultra-wide angle lens was needed for daily shooting depended on many factors.
From the perspective of the shooting scene, if you often shoot a wider scene, such as large buildings, magnificent natural scenery, wide streets, or large gatherings, the super wide-angle lens could incorporate more scene elements into the picture and show the grandeur of the scene. For example, when shooting a huge building complex like the Forbidden City, the super wide-angle lens helped to show its magnificent full picture.
From the perspective of creative effects, if you wanted to shoot a photo with a visual impact, such as a contrast effect of a small person or a photo that emphasized the sense of space, distance, and layering, a super wide-angle lens was a good choice. Under certain circumstances, the distortion effect of the ultra-wide-angle lens could also be used to take photos with abstract artistic beauty.
In portrait photography, if you want to take a portrait photo with long legs or want a special image effect, the super wide-angle lens can also play a role.
However, the super wide-angle lens also had some challenges. For example, when shooting a wide scene with a strong sense of depth and large divergences, if used incorrectly, the picture would easily appear hollow and the main body would not be prominent enough. Moreover, the super wide-angle lens had high requirements for the aesthetic ability of composition and shooting skills, so not everyone could easily control it.
Therefore, if the photographer was good at controlling the ultra-wide-angle lens, and there were more scenes suitable for the ultra-wide-angle lens in daily shooting, then the ultra-wide-angle lens was necessary. On the contrary, if the photographer was difficult to control or the shooting scene was mostly small, and the subject needed to be highlighted, the ultra-wide-angle lens might not be needed.

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.

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.

What are the advantages of a low angle lens?The depression angle lens had the following advantages:
1. The description of the environment, location, number distribution, distance, and distance was usually rigorous and realistic.
2. It had the effect of reducing the background. When the background was water, grass, and other simple scenery, it could obtain a pure background, thus avoiding the messy scenery on the horizon.
3. It was beneficial to show space, scale, and level. It could show the clear sense of spatial perspective of the distant and distant scenery. It was also beneficial to show the momentum or terrain of the main body of the picture, such as mountains, fields, military parades, etc. It was also beneficial to show the relationship between objects.
4. The visual object would naturally become small, reducing its threat, and relatively increasing the threat of the subjective perspective. It could also be used to highlight the threat that was too great, and the subjective perspective seemed to be unable to resist.
5. It could make the character appear weak.
6. When the scene was dark, it would create a crazy and terrifying atmosphere, causing people to feel chaotic in the space.
