The basic knowledge of the micro-single fixed-focus lens was as follows: * * 1. Strengths ** 1. * * Excellent image quality ** - In general, its performance in terms of resolution, out-of-focus imaging, anti-glare ability, and distortion control was better than that of a zoom lens of the same grade. For example, when a fixed-focus lens was used to shoot a landscape, it could more clearly show the details in the distance, and the distortion at the edge of the picture was smaller. 2. * * Portableness ** - The structure of the fixed-focus lens was relatively simple, the design complexity was low, and the focal length was single. This made the body of the mirror more compact, and it was easy to carry while ensuring better image quality. For example, when traveling, a small fixed-focus lens would not add too much burden to the luggage. 3. * * Large aperture characteristic ** - It was easy to achieve a large aperture with a fixed-focus lens. Compared to the common "big three-dimensional" zoom lens, its aperture was usually larger. A large aperture could obtain a shallow depth of field, thereby achieving a better background blurring effect. In portrait photography, it could highlight the main body and make the separation between the character and the background more obvious. * * 2. Different focal lengths and lens recommendations (Canon as an example)** 1. * * Wide-angle ** - The RF16f/2.8 was the recommended lens. Although there were more wide-angle zooming lenses, the quality of the lens was high and the price was relatively cheap (about 2K). 2. * * Short focal length ** - For half-frame cameras, 24mm and 35mm lenses were good. They had a larger aperture and anti-shake function, but 35mm lenses were more recommended. For full-frame cameras, 35mm lenses were also recommended. It was a relatively standard human lens, and the price was basically around 4K. The 28mm lens cost about 2K and was also available as an option. 3. * * Middle Jiao ** - I recommend the RF85 f/2 lens. The RF50f/1.8 was not recommended. Unless the price was around 1K, the image quality was poor when the aperture was fully open. The probability of purple edges was high and serious, and the focus was slow and noisy. If the budget was sufficient, the RF85f/1.2 was also a good choice. The 85mm focal length was recognized as the king of fixed focus portraits, providing good blurring and photo effects when shooting outdoors. 4. * * Telephoto ** - The RF100f/2.800 micro lens was a classic. It was suitable for macro and close-up shots and cost about 10K. In theory, the photorealistic effects of the RF135f/1.8 were better than the RF85f/2. The blurring was more obvious and the atmosphere was stronger, but the price was about 15K. 5. * * Ultra Telephoto ** - If you had to choose a fixed-focus lens, you could consider the RF800f/11, which was about 1K more expensive than the RF600f/11. For users who were familiar with using the 600mm lens to find and track targets, the 800mm lens was also easier to control. However, in the field of super telephoto lenses, zooming lenses were more popular because it was easier to find a target. However, the fixed-focus lens did not have an absolute advantage in all aspects: * * 3. Current development situation compared to zooming lenses ** 1. * * In terms of image quality ** - In the past, fixed-focus lenses were much better than zoom lenses in terms of image quality, but now in the era of micro-lenses, the image quality of mainstream brands (Canon, Soni, Nikon) had greatly improved. Although there was still a small gap compared to the top fixed-focus lens, the gap was not obvious compared to the mid-range fixed-focus lens or even some old top-notch fixed-focus lenses. In some aspects, the zoom lens even performed better. In terms of satisfying the needs of most commercial photography (not especially those that needed a large aperture), the large three-dimensional zoom lens was a good choice because of its high work efficiency. 2. * * Large aperture characteristics ** - Large apertures were no longer exclusive to fixed-focus lenses. There were already brands that had introduced super large aperture zoom lenses, such as Canon's RF28 - 70mm f2.0 lens, which could achieve a constant f2.0 large aperture in the common focal length of 28mm-70mm. It could replace many ordinary f1.8 aperture fixed-focus lenses, and the quality of each focal length was excellent. Tenglong, Sima, etc. also had similar large-aperture zoom lenses. As technology developed, there would be more and more such lenses. 3. * * Video shooting ** - At a time when video shooting had become a mainstream creative method, zooming lenses had an advantage. Video shooting required a large zoom range, constant aperture, stable image quality, and good anti-shake performance. There were many zoom lenses that met these conditions, such as the 24 - 105mm F4 zoom lens. For video shooting, the need for a fixed-focus lens was reduced because the video did not require a large aperture (a large aperture would make the depth of field of a large-sized sensor device too shallow, which was not suitable for video subjects; for small-sized sensor devices, a large aperture could also be achieved in a zoom lens). However, for plane photography, high-quality, large-aperture fixed-focus lenses were still the first choice for many photographers, but they were more often used in conjunction with zooming lenses rather than a single choice. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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. The lens had excellent resolution and sharpness. It used a super ED lens to suppress the dispersion phenomenon, and with a nano-crystal coating, the dispersion control effect was especially good. 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.
