Basic knowledge of micro-single fixed-focus lens

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>

Do you use a single-lens reflex camera or a micro camera for micro movies?

If you choose a DSLR, some DSLR, such as Canon 5d4, 1dx2, Nikon d500, d850, etc., have 4K or even super-capture functions. Moreover, the DSLR video shooting function is convenient and easy to use. It is solid and durable, and its performance is stable and reliable. There is no problem of heat, crash, and poor battery life when shooting videos. However, the video function of the DSLR was weaker than that of the mini-camera. If you choose a micro camera, like the S series of the A7 series (such as the A7S3), it is the main video shooting. It has super high-sensitivity performance, strong video shooting performance of 4K 120P with auto-focus, professional color configuration, strong focus and auto-focus ability, and five-axis anti-shake function. The video quality of the Pantheon gh5 was one of the best in its class. The 4K 10bit 4:2:2 internal recording quality was not inferior to many more expensive DSLR or micro-single cameras, and it also had five-axis anti-shake. Fuji's XT4 had 6.5-speed anti-shake, strong autofocus, and 240P full HD video capture in addition to 4K. In addition, the micro-single was mainly responsible for the "camera" work in the business. It was suitable for shooting dynamic images such as micro-movies. The quality was good, the price was cheaper than high-end cameras, and the functions were comprehensive. In short, both DSLR and micro cameras could be used for micro film shooting. They could choose according to their own needs in terms of function, image quality, budget, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Dog fixed-focus camera

In dog photography, the fixed-focus lens had its own unique application. If you were shooting dogs indoors, considering the poor lighting and small space, you could choose a 24 - 85mm fixed-focus large aperture lens. The large aperture could guarantee the shutter speed of indoor shooting and improve the image quality with relatively low sensitivity. In addition, if you use a fixed-focus lens to shoot, you must open the aperture completely. In terms of the characteristics of the fixed-focus lens, the angle of view of the 85mm fixed-focus lens was about 28 degrees. With the deep background of the large aperture, the background could be easily simplified to highlight the subject during composition, and the background blurring effect was better. When shooting a full-body close-up, the shooting distance was about 1.5 meters to 5 meters. This distance allowed the photographer to maintain a comfortable distance from the dog to avoid the pressure on the dog when the distance was too close. The image quality of the 85mm fixed-focus lens was usually higher. However, the fixed-focus lens had a fixed angle of view. If the shooting distance and angle were not controlled well, the picture would lack variation, which would easily make a group of photos seem monotonous and cause aesthetic fatigue. For beginners, if they only wanted to buy a single lens, considering its functionality, it was recommended to choose a telephoto lens with a larger focal length range such as 70 - 300mm f/4.5 - 6.3. However, this was not a fixed-focus lens but a reference given from the perspective of the lens. When using a fixed-focus lens to shoot a dog, you can learn to use the background to make the picture more atmospheric and layered. When taking a set of photos, try to make the dog's physical emotions change as much as possible. Control the light and tone, try to use backlighting and side lighting, and choose to shoot in the morning or sunset at dusk to make the photos more brilliant. <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. 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>

DSLR and micro-single shooting micro-movie video

If one wanted to shoot a micro movie video, there were advantages and disadvantages to both an DSLR and a micro camera. From the perspective of the shooting effect: - In terms of optical quality, both the DSLR and the micro-lens had larger light-sensitive components and high-quality changeable lenses. This structure could guarantee better results when shooting micro-movies than mobile phones and other devices. For example, in a dark environment, with a large aperture lens, the video could be shot with pure and rich details. - In terms of bit stream, hue sample, and other parameters, the DSLR and the micro DSLR had more advantages than the mobile phone. They could set a larger bit stream, a higher hue sample rate, and a wider variety of frame rates, which allowed the captured video to have more room for adjustment in post-processing, while the mobile phone could not achieve such professional indicators due to heat dissipation, storage, and other limitations. In terms of control and compatibility: - When shooting videos with a single-lens reflex camera and a micro-single camera, more auxiliary equipment could be attached. For example, it could be installed on a tripod, a stabiliser, and other devices through a universal screw hole. It could also be connected to an external recorder and display device through an interface. It could also be connected to external microphones, wireless microphones, and other audio equipment through an independent audio interface to facilitate the creation of micro-movies. Moreover, their grip comfort was suitable for shooting videos, and the physical buttons were designed to quickly adjust the parameters during shooting, while the mobile phone could only be operated by touch and was relatively amateur. Anti-shake performance: - DSLR and micro-single usually had five-axis anti-shake, and could also link the optical anti-shake of the lens and turn on the electronic anti-shake in the camera. Multi-dimensional cooperative anti-shake allowed hand-held shooting to obtain better image stability. Most mobile phones used electronic anti-shake, which would reduce the image quality due to large image trimming. However, compared to DSLR cameras, micro-cameras also had a unique advantage in shooting micro-movies: - The focus performance of the micro-camera was generally better than that of the DSLR. When shooting some micro-movie scenes that needed to quickly switch focus or follow the focus, the micro-camera could capture the focus more accurately and ensure that the main body of the picture was clear. - Some microfilms might have more options for video functions. For example, some microfilms might provide special color modes or optimized coding format for video shooting, which would help improve the visual effect of the microfilm. DSLR cameras also had their own value when shooting microfilm videos: - The optical viewfinder of a DSLR might give the photographer a different framing experience in some shooting scenes, and its structure might be more suitable for use in some special environments. For example, the optical viewfinder of a DSLR could see the picture more clearly when shooting under strong light. In short, both the DSLR and the micro-camera could be used for micro-movie video shooting. The specific choice depended on the needs of the photographer, budget, and familiarity with the equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Canon 400f5.6 fixed-focus lens was ridiculed

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>
