Mobile phone macro and single-lens reflex lens
The macro lens of the mobile phone could allow the mobile phone to achieve functions that the original camera could not achieve. It solved the problem that the original camera could not focus on close-up objects. It could capture clear details of objects at a closer distance, and it could also simulate the aperture blurring effect of a single-lens reflex camera. It was suitable for shooting small objects such as jewelry, insects, and cultural toys. When shooting with the macro lens of a mobile phone, the lens should be close to the scene. To ensure that the focus is clear and the mobile phone is stable, you can use a tripod or place it on a stable surface. If you want to shoot macro works with a black background, you can use black clothes as the background and pay attention to sufficient light. Most mobile phone macro shooting parameters are automatically set by the system, but you can improve the shooting effect through some techniques, such as using light, adjusting focal length and exposure compensation. Different phone brands and models may have different macro shooting functions. You can learn more tips and precautions from the phone manual or online tutorial. The single-lens reflex camera was also known as the single-lens reflex viewfinder. This was a popular viewfinder system. At the center of the camera was a movable mirror, and the light was reflected upward through the mirror onto the frosted glass. In the early days, it was used to view the frosted glass. Later, in order to correct the image reversal problem, there was an eye-level SLR camera. A pentaprism was installed above the frosted glass to change the light path and send it to the eyepieces to form an image that was upright up and down and corrected left and right. The shutter was located in front of the film. When framing, the shutter was closed. When shooting, the mirror was flipped up and the shutter was opened to let the light reach the film. After shooting, the mirror was reset. As for the single-lens reflex lens, the common 400mm fixed-focus lens for mobile phones used for telephoto shooting was an example. When installed on a mobile phone, it could let the mobile phone experience the beautiful scenery brought by telephoto shooting. The scenery was transparent and clear, and the edge of the person's depth of field was optimized. The zooming was smooth and smooth, and the video effect was amazing. The overall metal texture was not inferior to the camera lens. It could also be matched with a hood, a triangular table stand, a cloud platform, and so on. It could be used as a telescope in the hand, making it convenient to carry and store. Mobile phone lenses and single-lens reflex lenses had their own characteristics. Mobile phone macro lenses were easy to achieve macro shooting on mobile phones, while single-lens reflex lenses had their own complex and professional optical structure and functional features.

How to install a single-lens reflex lens on a mobile phone
The following is a way to install a DSLR lens on a mobile phone: first disassemble the back cover of the mobile phone, remove the ultra-wide-angle and periscope telephoto lens modules that may be blocked, and only keep the main camera.(For example, the main camera of the Xiaomi 11Pro's GN2); then disassemble the main camera and remove the original lens, leaving only the LCD; then use the lens screw ring to fix it on the LCD (you can also use a 3D printed back cover to fix the screw ring in a more secure way), and then install the single-lens reflex lens; you can also find a phone case and dig a hole in the lens position to cover it as a back cover. However, this modification method may have certain risks. For example, the fixing method may not be strong enough, beautiful enough, and may even damage the phone components. There may also be situations where the photo is red, the focus is problematic, and the shooting effect is not good. This may be due to the sensor's custom correction algorithm to adapt to the phone lens. It was also possible to use a simpler method, such as using some external lens products that came with a phone case and the lens could be directly installed. The DSLR lens could be directly installed on the corresponding position of the phone case. It should be noted that DSLR lenses have different types of bayonet. Their design purpose is to ensure that the camera lens is connected stably. Under normal circumstances, it cannot be used directly on the phone, and it is limited by the size of the phone's sensor, so it may not be completely universal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Mobile phone macro lens and telephoto lens
The macro lens and telephoto lens of mobile phones had the following different characteristics in macro photography: * * 1. Magnification ** 1. * * macro lens ** - A professional macro lens could achieve a 1:1 or higher magnification, which could magnify small objects to the same size or even larger than the real thing, and could capture the details and texture of small objects very well. 2. * * Telephoto lens ** - Telephoto lenses had limited magnifying power. Although they could magnify small objects appropriately, they were not as good as professional macro lenses. * * 2. Image Quality ** 1. * * macro lens ** - It usually uses high-quality lenses and advanced optical design, and the image quality is excellent. It could produce clear, sharp, and low-distortion images, not only ensuring the detailed expression of macro photos, but also retaining the true color and texture of small objects. 2. * * Telephoto lens ** - When a telephoto lens was used for macro shooting, the image quality was different from that of a professional macro lens. There might be problems such as insufficient resolution, distortion, and noise, which would affect the clarity and realism of the image. * * 3. Portableness and ease of use ** 1. * * macro lens ** - The professional macro lens was large, and it would increase the cumbersome feeling when installed on the phone, affecting the maneuverability. Moreover, due to the extremely close focus, the requirements for hand-held stability were very high. The camera needed to be held stably or use auxiliary equipment such as a tripod. The working distance was close and the light of the object might be blocked, so additional light filling equipment was often needed. 2. * * Telephoto lens ** - The telephoto lens was a type of phone lens. It didn't have the problem of increasing the size of the device and was relatively portable. When using it, it didn't need to consider the influence of distance on stability and light like a macro lens, so the operation was relatively simple. * * 4. Shooting Effects ** 1. * * macro lens ** - It could display the microscopic world that was usually difficult to perceive. It was especially suitable for capturing tiny objects that required high magnification, such as the texture of insect wings and dewdrops on flowers. 2. * * Telephoto lens ** - When a telephoto lens had both telephoto and macro functions, it could achieve a good macro effect on some mobile phones. However, there might be differences in focus accuracy, depth of field control, separation of the main body from the background, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Mobile phone lens macro evaluation
The macro camera function of the phone lens had its own characteristics on different brands and models. ** 1. Microscope Shooting with Huawei Phone ** 1. ** In terms of hardware and details ** - For example, the Huawei P-series had an ultra-sensory camera that performed amazingly in macro photography. It could clearly capture the details of tiny objects, such as the texture of petals and the fur of insects. Take the Huawei P60 Pro as an example. Its super macro, especially telephoto macro, had excellent performance. When shooting lively small objects such as black ants, the success rate of using the super macro 10x zoom was higher. Even if the lighting was not good, it could still be clear and realistic inside the focal point, and fascinating outside the focal point. - When shooting tiny objects such as flower stamens, switch the zoom ratio to 10x. As long as it is stable and the focal plane is found, a clear picture can be taken, such as dragon spit beads, red camelia stamens, and even fine dandelion flower buds. Water droplets or dewdrops were difficult to shoot, but the P60 Pro's telephoto macro could easily shoot them well. Compared to professional macro lenses such as Canon's New Baiwei (the macro effect was not ideal when the zooming ratio was 1:1), the P60 Pro's super macro 10x zoom could shoot the water droplets bigger and rounder. 2. ** Focus and Image Quality Control ** - In terms of focusing, most of the time, semi-autofocus (autofocus and click on the subject at the same time) was enough. The focus was fast and accurate. And even if a larger zoom was used, such as a super macro 10x zoom, the USB could be controlled below 200 to minimize noise and ensure quality. For example, when shooting on rainy days, the sensitivity was slightly higher than 200, and the quality was still passable. When the USB was 50, the color tone was fine and smooth, not inferior to the camera. ** 2. iPhone macro camera ** - The iPhone had always been known for its excellent image quality. In macro photography, its optimized algorithm and precise focus system made the macro photos extremely high in color reproduction. The picture was delicate and natural. The color correction was quite good, and it could accurately display the original color of the object. ** 3. Oppo macro camera ** - Take the OOppo Find X7 Ultra as an example. The 6X telephoto macro shooting function was added through the system update. Compared to the iPhone 15 Pro Max, the Samsung S23 Ultra, and the Vivo X100 Pro, it performed better in 6X mode. It had 3X and 6X dual periscope telephoto lenses, and the algorithm had been upgraded to the new generation of super light and shadow imaging system. With the support of Hasse color, the effect of the telephoto macro shot was not only layered in the light, but also detailed in the dark. The color was also very natural, and the photo did not look distorted. ** 4. Microscope Shooting with Vivo ** - In comparison with other models, such as in 3X mode, the Vivo X100 Pro took into account some blurring effects. The close-up feeling was relatively strong, retaining more contrast between light and dark. The flower details showed the quality of the 3X light lens, and the clarity was good. In 6X mode, in addition to the different color adjustment preferences, the optical quality of the lens was relatively similar to that of the OOppo Find X7 Ultra. It could simulate the blurring effect of professional lenses, and the close-up of the picture was full. The overall picture quality was higher than that of the iPhone 15 Pro Max and the Samsung S23 Ultra. When magnified to see the details, the edge of the blade had a higher picture quality. ** 5. Microscope Shooting with a Samsung Phone ** - In comparison to other models, such as in 3X mode, the picture of the Samsung S23 Ultra was brighter. The leaves were almost unblurred, the details of the flowers and leaves were clear, and the color saturation was higher, making it more eye-catching. In 6X mode, the performance was similar to that of the iPhone 15 Pro Max. The leaves were brighter, and the picture had a certain blurring effect. However, when magnified, the algorithm traces were more obvious. There was a smearing feeling and the quality of the edge of the leaves had decreased, but the color was still saturated and pleasing. In general, different brands of mobile phones have their own merits in macro shooting. Huawei excels in detail capture and telephoto macro of specific models; Apple has advantages in color reproduction and focusing; OOppo has a good comprehensive performance in telephoto macro function and shooting effect;Vivo has remarkable performance in blurring effect and picture quality clarity; and Samsung has its own characteristics in color saturation. The user could choose a suitable mobile phone for macro shooting according to their needs for shooting details, color, image quality, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Mobile phone single-lens reflex practical photography skills
Here are some practical photography techniques for cell phones and DSLR cameras: - ** Precise exposure **: - The camera of a mobile phone was the same as a single-lens reflex camera. Only by exposing it accurately could a good photo be taken. It's easier to take good photos when there's enough light outdoors, but you still need to find the best light. In the shadows and other places where there's insufficient light, you can use white paper to reflect the light, or use a flashlight or other mobile phone screens to fill up the light. Try to avoid using mobile phone flashes. - When the lighting was complicated, the camera could adjust the sensitivity (USB) and shutter speed according to the scene. For example, in low light, low sensitivity can guarantee the quality of the picture, and the shutter speed affects the brightness of the picture. When shooting moving objects, you can first set the sensitivity to 100 to ensure the quality of the picture, and then adjust the shutter speed to the ideal brightness. - ** In terms of composition **: - Taking pictures with a mobile phone was like using professional equipment. One had to consider the level of the picture and make clear the master-slave relationship between the front, middle, background, and the subject. For example, the subject would be placed in the front to make the background blurred, or the subject would be shot through a window or mirror to increase the content and interest. - Try shooting from different angles, such as front, side, head-up, and looking up to break the monotonous image. For a DSLR, when shooting a building, you can use the pillow distortion of the telephoto lens to compress the space to make the picture compact and the buildings dense and oppressive. You can also use symmetrical composition to give a steady and magnificent visual impact. When shooting, pay attention to the sense of space extension or depth. - A simple composition was more suitable for outdoor architectural shooting. When shooting with a mobile phone, it was easy to have graininess due to the low resolution. When choosing a single-color image, the DSLR could shoot a simple effect. - ** Other aspects **: - Using reflections to enhance the image, it was often used to shoot buildings or city characters. - Backlighting can produce dramatic story effects, and shadows can highlight the soul of the character. It is suitable for Japanese, fresh, and film style photos. - Capturing small details fits the theme of the photo, such as capturing the reflection of raindrops on a bright surface. The macro lens can meet the needs of detail photography. - When shooting on the phone, you can turn on HVR mode to deal with backlighting or scenes with a large light and dark ratio. The camera will take multiple shots with different exposure settings and synthesize them so that the dark and bright parts have better performance. - The streamer shutter function of the mobile phone could achieve the professional image effect of the slow shutter of the single-lens reflex. There were shooting modes such as heavy traffic, light painting, scribbling, silk flowing water, gorgeous star orbit, and so on. - When shooting with the phone, adjust the white balance setting according to different subjects. For example, you can set it to cloudy mode at sunrise and sunset to show warm colors. After sunset and before dawn, you can set it to fluorescent light or white light mode to show cold colors. - When shooting with a mobile phone, you can look for beautiful light and shadow, avoid natural light at noon and 2 hours before and after; when shooting against the light, you can look for transparent objects as the subject and avoid strong light sources. Silhouette techniques can also be used to highlight the outline and the beauty of the light. - In cell phone photography, if you wanted the subject to stand out, you could simplify the background, such as clearing the desktop, using a clean wall, grass, and sky as the background, and try to make the theme and background as complementary colors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The influence of single-lens reflex camera on mobile phone photography
DSLR cameras had many effects on mobile photography: * * 1. Shooting Techniques ** 1. * * Focus Technique ** - DSLR cameras had a complex and precise focusing system. Traditional single-lens reflex cameras could achieve fast and accurate focusing through the use of mirrors and phase detection focusing technology, especially when shooting moving objects. During the development of mobile photography, it gradually drew lessons from similar focusing concepts. For example, the autofocus function of many mobile phones now, although the implementation method was based on algorithms, the design also pursued the convenient focusing experience of "pointing where you want to be clear" to meet the needs of users for the subject to be clear. 2. * * Exposing Control ** - DSLR cameras provided a variety of exposure modes, such as manual exposure (M), aperture priority (A or Av), shutter priority (S or Tv), and so on. The user could precisely control the amount of exposure according to different shooting scenes and creative needs. In the early days, mobile photography was mainly based on automatic exposure, but with the development of technology, manual exposure adjustment functions began to be added. This development was partly inspired by the single-lens reflex camera to meet the needs of photography enthusiasts for more shooting control. For example, when shooting at night or in special scenes under strong light, manually adjusting the exposure could make the picture look better. 3. * * Picture composition assistance ** - The viewfinder or display screen of an SLR camera could use auxiliary lines such as the nine-square grid to help the user better follow the composition principles, such as the three-point rule. Mobile photography also borrowed this method. It provided a grid line function in the camera settings to make it convenient for users to align the picture elements and take photos with a more reasonable composition. * * 2. Image Quality and Function ** 1. * * Quality Pursuit ** - DSLR cameras had obvious advantages in terms of image quality, such as light capture, noise control, and dynamic range, due to their larger sensor and high-quality lenses. This prompted the development of mobile photography to constantly seek ways to improve image quality. Although mobile phones couldn't improve the image quality by replacing large-sized light-sensitive components like DSLR cameras, mobile phone manufacturers used algorithm optimization to reduce noise and increase dynamic range, trying to narrow the gap in image quality with DSLR cameras. 2. * * Effect of background blurring ** - Through optical equipment such as a large aperture lens, a single-lens reflex camera could easily achieve a natural and beautiful background blurring effect, and the degree of blurring could be precisely controlled. In order to achieve a similar effect, mobile phone photography began to use an algorithm to simulate background blurring. Although the blurring effect of mobile phones was mostly achieved through digital smearing, and the effect was still different from that of single-lens reflex cameras, it was constantly improved under the influence of single-lens reflex cameras to meet the user's pursuit of the main body and background blurring effect. * * 3. User demand and market ** 1. * * Stratification of User Requirements ** - DSLR cameras had always been an important tool for professional photography and photography enthusiasts. Their advantages in terms of image quality and functionality met the requirements of high-end users for photography quality. The development of mobile photography was based on satisfying the daily recording needs of the public. Some users were influenced by the high-quality photography represented by the single-lens reflex camera and began to put forward higher requirements for mobile photography, such as better image quality and more shooting functions. This prompted mobile phone manufacturers to continuously improve their mobile phone photography functions to attract more users who pursued the quality of photography. 2. * * Market Competition and Discretization ** - In the photographic equipment market, there was a certain competitive relationship between single-lens reflex cameras and mobile photography. The existence of the single-lens reflex camera prompted the continuous innovation and development of mobile photography to occupy a place in the market. Mobile photography, on the other hand, relied on its convenience and the convenience of sharing on social networks to form a differentiated competition with DSLR cameras. For example, the various filter functions and convenient post-editing functions of mobile phones were also developed in the competition with DSLR cameras to meet the needs of users for fast and convenient shooting and sharing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to use the macro lens of the mobile phone
The following is how to use the macro lens of a mobile phone: 1. ** Mount macro lens **: Mount the macro lens on the phone lens. Most macro lenses on the market are fixed by clamping or magnetic attachment. When installing, make sure that there is no gap between the macro lens and the phone lens to avoid affecting the imaging effect. 2. ** Adjusting distance and focal length **: The working principle of a macro lens is different from that of a mobile phone lens. When shooting, the lens needs to be as close to the subject as possible. The focal length was very short, and it needed to be fine-tuned to get a clear focus. The distance between the front and back of the phone could be fine-tuned or adjusted by using the phone's own focus function. 3. ** Maintain stability **: The image range of the macro lens is small. You need to keep the phone stable to take clear photos. You can use a tripod or a hand-held stabiliser, or you can use the phone's built-in timer function or remote shutter to avoid shaking. 4. ** Choose the right light **: The photo taken by the macro lens needs more light to show the details. You can shoot in a well-lit environment, or use an external flash to supplement the light, and you can also use a reflective plate to control the direction and intensity of the light to obtain better imaging results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single lens reflex lens parameters
The 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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
80,000 yuan single-lens reflex lens
Canon's 800mm fixed-focus lens cost about 84,000 yuan. It was a lens for top professional users. It looked particularly large and heavy. After installing the 5D4, it was estimated to weigh more than 5 pounds. There were a lot of control buttons on the side of the body, making it easy to switch between focusing mode and focusing distance. In terms of image quality, the in-focus was clear and sharp, and the out-of-focus melted like cream. However, the high price and limited usage made it relatively niche. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon single-lens reflex camera macro photography is based on that
Canon DSLR cameras can be used to shoot macro photos by pressing the macro button (the icon of this button is a flower and two leaves, located next to the MENU button). In old-fashioned cameras, the macro button might be on the lens. In Canon DSLR cameras, the macro button was usually located on the right side of the camera. Below it was the focus mode selection button, and above it was the light measurement mode selection button. When using it, you need to set the camera to macro mode first, then press the macro button, and the lens will enter the macro shooting mode, which can magnify the subject to a ratio of 1:1 or larger, but pay attention to the adjustment of the focusing distance to ensure that the subject is clear. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
