Canon had two types of 600mm fixed-focus lenses, the RF600mm F11IS, and the RF600mm F4. The RF600mm F11IS ATM lens has the following features: - The price was relatively affordable. For example, on the e-commerce platform, the time limit of the RF600mm F11IS ATM ultra-telephoto fixed-focus lens dropped from 5298 yuan to 4499 yuan. - The lens structure consisted of seven sets of 10 lenses, a filter diameter of 82mm, a closest focusing distance of 4.5 meters, a fixed F11 aperture, and a drive unit driven by an ATM step motor. It weighed 930 grams. - It has a DO lens. One piece of DO lens can achieve the compensation effect of fluorite lens and aspheric lens. It uses a set of seamless double-layer structure DO lens, which can cause more light to be refracted, suppress glare, and improve image quality. - When paired with the RF1.4x or RF2x, they could achieve an ultra-telephoto focal length of 840mm or 1200mm respectively. - The lightweight mirror body and the IS Image Stabilizer with a shutter speed of up to level 5 provided strong support for hand-held shooting. It was suitable for shooting wild birds, animals, airplanes, trains, scenery, outdoor sports, and many other subjects. The RF600mm F4 super telephoto fixed-focus lens weighed 3090 grams. It was an excellent bird-hunting lens that could be used with the Canon R series 'small and portable body to meet the needs of high quality and lightweight. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon had several 85-degree fixed-focus lenses. The following are some of the features of the Canon 85 fixed-focus lenses: ** I. Canon RF85mm F1.2L USM** 1. ** Picture quality ** - It had excellent image quality and exquisite out-of-focus effects. When the aperture was fully opened, the image quality reached a new height, and the image was extremely sharp. Moreover, it used the AR lens, so it was almost impossible to detect the edge dispersion of the image when it was fully opened. It could be used in all kinds of environments with full aperture. 2. ** Focus ** - Since the Canon's Eos R/Eos PR had a dual-core focusing system, coupled with the driving force of the lens motor, it had excellent focusing speed during daytime shooting or in low light. 3. ** External Scorch Effect ** - It could produce a mesmerizing blurring effect and better highlight the character, making it suitable for portrait photography. 4. ** Grip feeling ** - The lens body was coated with a matted black matte material, which had good anti-slip and anti-dirt effects. In addition, the front and back center of gravity were reasonably arranged, so it felt good to hold it when shooting. ** II. Canon RF85mm F1.2L USM TS ** - On the basis of the same function as the RF85mm F1.2L USM, a "smooth defocus coating" was added, allowing for a smoother and more beautiful off-focus. ** 3. Canon RF85/2 macro IS ATM ** 1. ** Picture Quality ** - It should have a good resolution, distortion, and dispersion performance, but there are shortcomings such as large field curvature and aberrations, and the blurring outside the focal point will not be particularly smooth. 2. ** Focus * - It used a gear type STM-type stepping motor, which did not perform well in terms of focusing speed and working noise. However, with the addition of a focus stopper, the actual shooting experience was better than the RF35/1.8 macro IS STM. 3. ** Anti shake ** - When paired with the IOS-R, the double-detection IS could achieve Level 5 anti-shake, and when paired with the IOS-R5 and IOS-R6, the body and lens anti-shake worked together to achieve a maximum of Level 8 anti-shake effect. 4. ** Protective ** - The front of the lens was coated with a fluorite coating, but there was no dust-proof and drip-proof design. At the maximum magnification (0.5x), the effective aperture would drop to F3.3. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Although the Canon 400mm f5.6 fixed-focus lens had many advantages, there were also some aspects that were ridiculed. In terms of aperture, its maximum aperture was only f5.6. In the case of insufficient light, it might affect the shutter speed, resulting in poor shooting results. At the same time, it would also affect the background blurring effect. There was a lack of anti-shake function, and it was easy to blur when shooting with a hand-held camera. In terms of focusing distance, the closest focusing distance was 3.5 meters, which would be limited when shooting close-up objects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The fixed-focus lens was suitable for shooting various subjects, including portraits, scenery, indoors, and environments. Canon's 35mm fixed-focus lens was suitable for shooting culture and scenery. It was especially suitable for shooting small scenes of culture and scenery. It focused quickly and was often used to shoot landscape portraits and indoor portraits. Canon's 50mm fixed-focus lens was a standard lens. Its angle of view was similar to that of the human eye. It was suitable for shooting long-distance scenery and people.

Canon's 85mm fixed-focus lens was the golden focal length of portrait fixed-focus lenses. It was suitable for shooting portraits and had good image quality and practicality. As for the 135mm fixed-focus lens, some people called it a conscience lens. It was cheap and practical, so it was popular with everyone. In general, the fixed-focus lens was suitable for shooting various subjects, and the image quality was better than the zoom 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. 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. 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>
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 focal length of a fixed-focus lens depended on factors such as shooting requirements, style, and budget. The following are the characteristics of different focal length fixed-focus lenses for reference: ** 1. 35mm focal length (micro-wide angle lens)** 1. ** Strengths ** - The angle of view was closer to the eyes, and it could produce a natural and layered portrait effect. When shooting a portrait, some environmental elements could be incorporated. - It was suitable for shooting indoors, street scenes, and traveling scenes. 2. ** Flaws ** - The need for a closer shooting distance may cause distortion or unnatural stretching of the character, such as when shooting an upright half body and a big head. - It required a high level of composition ability, because the picture contained a lot of information, and it was easy to have a messy or boring effect. - A high aperture value was required. Due to the large depth of field of the wide-angle lens, it was more difficult to capture the effect of shallow depth of field and background blurring. ** 2. 50mm focal length (standard lens)** 1. ** Strengths ** - The angle of view was close to the focal range of the human eye. It could shoot a balanced and prominent portrait effect. It could adapt to portraits, animals, still life, streets, cities, and many other scenes. - It was the first choice for many people to get started with fixed-focus lenses. It was relatively cheap, had a large aperture, high quality, good sharpness, and was relatively easy to master. 2. ** Flaws ** - The angle of view was flat. The close-up shot was not as good as the 85mm lens, and the angle of view impact was not as good as the 35mm lens. It was difficult to shoot with characteristics and creativity. - It was more difficult to focus, especially when the aperture was fully open. It was easy to make mistakes that were out of focus or out of focus. - The limited space in the room made it difficult to shoot the whole body or half of the body. ** 3. 85mm focal length (medium telephoto lens)** 1. ** Strengths ** - The angle of view was relatively narrow. It could highlight the main body of the character, greatly blur the background, and create the effect of separating the person and the scene. It was suitable for shooting full-body portraits, half-body portraits above the waist, close-up scenes, and so on. - It was a very classic focal length in portrait photography. It had the reputation of a beauty mirror and a portrait mirror emperor. It also had a little decorative effect. - The image quality was basically the ceiling of all the cameras. 2. ** Flaws ** - Its usage was very limited. It was almost useless indoors, and it also needed to maintain a certain shooting distance outdoors. - The price and weight were both high, especially for large aperture focal lenses, because more glass components and more complicated structures were needed to achieve a large aperture and long focal length. - The camera and technical requirements were relatively high. It required a certain degree of anti-shake function and high photography ability to shoot better works. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It could also specify the control ring function, suitable for video recording. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The fixed-focus lens was suitable for group shots. When taking group photos, the best fixed-focus lens was a standard fixed-focus lens, such as a 50mm lens for a 135 camera or an 80mm lens for a 120 camera. The standard fixed-focus lens had many advantages. Its technology was mature, the quality of the lens was good, the image quality was excellent, and the price was relatively cheap. It had almost no distortion and could meet the requirements of group photos that did not allow exaggeration or reduction of distortion. The scope of the shot was basically the same as what the human eye could see. It had a real perspective effect and did not exaggerate or reduce the space. When taking large group photos, using a standard fixed-focus lens could ensure that the front and back rows of people were clear, the layout of the picture was reasonable and substantial, and there was no distortion of the middle. It also worked well when stitching panoramic photos, making every face clearly visible. However, if it was a group photo taken indoors and the indoor space was extremely limited, and the standard lens could not cover the entire picture, you could consider using a fixed-focus wide-angle lens because the distortion control of the fixed-focus wide-angle lens was much stronger than the zooming wide-angle lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
