Would you secretly change the lens of the camera when repairing it?
In some irregular maintenance channels, there might be cases of secret replacement. For example, when a certain treasure repaired the camera, it was exposed that a repair merchant had replaced the camera parts. The merchant promised that the same fault was not man-made for three months. However, after the problem occurred, the merchant first said that the welding spot on the USB board was man-made and could not be guaranteed. Then, he changed his words and said that the board burned and could not be turned on. Finally, the returned camera board was replaced and could not be used at all. Therefore, when repairing the camera lens, you should choose a formal repair channel, such as brand after-sales, reputable third-party repair shop, etc., and keep sufficient evidence to avoid this situation.

The camera lens is expensive
In the field of photography, expensive lenses had their value. Generally speaking, more expensive lenses had higher performance in terms of optical quality, workmanship, and performance. For example, in the field of medium and long focal length lenses, Canon's RF70 - 200mm f/2.8L IS USM was priced at 16999 yuan, and the Sony70 - 200mm F2.8GM OSS II was priced at 18999 yuan. These lenses were expensive, but they could provide better imaging results, excellent focusing performance, and good durability on their respective cameras. However, with the changes in the photography market, the relationship between price and value did not completely follow the traditional principle of "you get what you pay". In the micro-monocle era, although some high-end lenses had improvements such as quieter focusing, better design, and improved electronic functions, compared to similar lenses in the DSLR era, users felt less about the improvement in optical quality, but the price generally rose. Some of the affordable entry-level lenses, such as the 50mm f1.8 lens, were no longer as affordable as before. Branded lenses of this size were even hyped up to three times the release price. 24 - 105mm f4 or similar lenses were nearly twice as expensive in the micro-single era as in the single-lens reflex era. Although the optical quality had improved, there was no particularly huge breakthrough. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Does a single-lens single-camera have a lens?
" Standalone " usually meant that it only had the camera body and did not include the lens. Therefore, a single DSLR camera did not have a lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to stack the lens of a single-lens reflex camera
The full name of the DSLR was " single-lens reflex viewfinder camera." It only had one mount. In theory, it could only be connected to one lens for optical imaging. Under normal circumstances, the lens could not be stacked. However, there were special uses, such as reversing the lens or connecting the zoom lens. However, these still needed to rely on a pure optical lens to use. On the basis of this lens, you could stack the transfer ring, zoom lens, etc. to achieve different effects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Rotating camera lens material
In the reference materials, there were some materials about rotating camera lenses, such as "15 pieces of film/media material (4K), magnificent mountain scenery rotating lens shooting, looking up at cliffs, natural scenery, high-definition video, real shot", as well as "classic sci-fi movie lens rotating video template" and "atmospheric three-dimensional film lens combination display template", etc. These could be used as rotating camera lens material. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single lens reflex camera, wedding camera, general format
When shooting a wedding video with a DSLR, you can use the raw format. The raw format was better used in an emergency. The audio file was a semi-automatic file, and the image could be defined according to the aperture. In addition, the M file (manual file) could also be used during artistic creation. The automatic file could be used at the beginning of the wedding, and the M file could be used during the exchange of rings and the interaction between the two parties. It could capture photos and show details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Holding the camera lens in one hand
Holding the camera lens with only one hand was an unstable way of holding it, and it was usually not recommended in photography. Generally speaking, for a single-lens reflex camera or a micro-camera, the more correct and stable way to hold it was to hold the camera handle with the right hand, hold the bottom of the camera lens with the left hand, and keep your arms close to the waist to maintain stability so that you can turn the zoom lens to zoom. If it was a telephoto lens, the position of the left hand might need to be held a little outwards to ensure that the lens was stable. However, if it was for a special purpose, such as holding the lens while using the other hand to perform a specific operation on the lens (such as cleaning the surroundings of the lens and maintaining this state for a short time), it was a different matter. However, in this case, special care should be taken to avoid the lens falling off. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Shanghai Baoshan cleaning camera lens
The cleaning method of the camera lens is as follows: 1. First, he used an air hammer to blow at the lens, then he used a brush to brush off the dirt on the lens. 2. Then, he used a pen to remove the dust from the lens. 3. Then, use the lens paper to gently wipe the lens. Don't wipe the lens with your hand to avoid leaving oil stains. After wiping, you can blow it with an air hammer and wipe it again with the lens paper. If you need more professional cleaning, you can contact Shanghai Senmu Digital Image Technology Service Center. Their services include lens cleaning, covering the lenses of many brands of cameras. You can also use some tools such as lens pens to clean it. The lens pen uses carbon powder to absorb oil and has a better cleaning effect. You can also use a soft towel to wipe the surface of the lens with vinegar water or soda powder, and then use a dry cotton cloth to wash it with a suitable amount of water. However, you must pay attention to the brush. You can also use special dust-absorbing materials such as glass glue to remove the lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Original camera rear lens flash
The original camera's rear lens flash had a variety of application techniques when taking photos and videos: - ** Flash sync detection (for cameras)**: If it is a domestic camera, sync can be performed at a speed of less than 1/60 seconds. During the test, open the back cover of the camera without loading the film, adjust the aperture to the maximum, and aim the flash at the lens. If the flash is connected to the camera, put a mirror 40 cm in front of the camera lens, then press the shutter to make the flash shine. The eyes look forward through the lens. If you see a dazzling circular spot, it means that the flash is synchronized and can be used normally; otherwise, it is not synchronized and needs to be repaired. - ** Photographic Skills ** - ** Use the environment **: If there is a street light in the shooting environment, ask your friend to adjust the exposure to the lowest level first, then turn on the contrast filter. This can solve the problem of 80% of the scattered powder reflection in the night photo. At night, the camera would take a top-down view. If the head was slightly raised, the flash would lengthen the length of the neck, making the head and face look small. They could also create a difference in height for filming. - ** With the help of props and post-processing **: The background can be the white wall at home. After using the phone's rear camera to turn on the flash, adjust it with the wake-up picture. Choose Film- Mini90 as the filter, click Advanced Editor, adjust the clarity to 60, click Special Effects, choose Basic-Over-exposure, click Advanced Editor-adjust parameters, noise 40, size 72, intensity 37, filter 24. - ** Character preparation and auxiliary tools **: When taking photos with the rear camera, you can tie your hair appropriately, wear pink or blue clothes, and prepare dried flowers or roses as decorations. As the composition of the rear camera may be biased, a small mirror can be prepared to observe expressions and movements. When shooting in dim light, turn on a small lamp to make your skin look good. If you use a light camera, you can choose a mist filter plus a pink filter, find a clean wall or curtain as a monotonous background, put your phone on a tripod or ask a friend to help you shoot. - ** Video Shooting Techniques **: Turn on a mode with better image quality such as 1080p, turn on beauty and adjust the parameters, such as skin leveling 30, whiteness 24, clarity 50, big eyes 15, adjust the nose shrinking value according to your own situation (such as 30), add a blush to the makeup, switch to the rear, turn on the flash and start shooting. After shooting, you can directly save and repair the image quality to obtain the same creamy texture as the blogger. You can also tailor it according to the video. If you want a sweet girl's video, you can set up a small warm light behind you. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Heavy traffic, blurry camera lens
If a photo with a heavy traffic effect appeared blurry, there could be several reasons: 1. ** Shaking during shooting **: Unexpected shaking during shooting will blur the picture. Especially when shooting scenes that required a certain amount of exposure time, even the slightest shake would be recorded if the camera was held. It is recommended to use a tripod to stabilize the camera to avoid blurring the picture due to shaking hands. 2. ** Shutter speed is not set properly **: If the shutter speed is too slow, the image may be blurred. Although a slow shutter speed could give the effect of a busy scene, if it was too slow, not only would the picture be too dim and have a gray feeling, but the picture might also be blurred due to the movement of the car or the slight shaking of the camera. If you wanted to solve this problem, you could try to increase the exposure time and use a tripod to ensure the stability of the image. 3. ** Filthy lens **: Filthy lens is a problem that is easily overlooked. Whether it was a mobile phone or a camera, dirt or dust on the lens would cause the image to be blurry and unclear. Before filming, the lens should be wiped with a clean cloth. 4. ** Focus error **: If you don't focus properly, the image will be blurred. When shooting a busy scene, you need to make sure that the focus is in the right place, such as the car you want to stand out or a specific part of the scene. 5. ** Aperture selection **: The size of the aperture will affect the depth of field to a certain extent. If the aperture is not selected properly, it may affect the overall clarity of the image, resulting in the image looking blurry. 6. ** Problem of sensitivity (USB)**: Aperture, shutter speed, and sensitivity are the three elements of exposure, and the three complement each other. If the sensitivity setting was not reasonable, it might affect the image quality and cause the image to be blurry. 7. ** Light factor **: The quality of the light directly affects the quality of the photo. If there was insufficient light, for example, when taking a photo of a busy night scene, the photos taken under the dim light would easily appear blurry and gray. At this time, you can use a tripod or a mobile phone stand to stabilize the shooting equipment, increase the exposure time, and make the picture brighter and clearer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to choose the telephoto lens of the camera
When choosing a telephoto lens for a camera, many factors needed to be considered. First of all, it was necessary to make clear the purpose of buying a telephoto lens, whether it was used to shoot portraits, scenery, or other specific scenes. There were four common types of telephoto lenses: medium telephoto lenses (such as 70 - 200mm), telephoto to super telephoto zoom lenses (such as 70 - 300mm, 200 - 400mm, 100 - 400mm, etc.), and fully fixed-focus super telephoto lenses (such as 500mm, 600mm, 800mm). Different types had different usage opportunities and preferences. If it was just to gather the focal length, 70 - 200mm or 70 - 300mm was usually enough. The image quality of 70 - 200mm was better than 70 - 300mm, but the price was relatively higher. When choosing between these two lenses, one also had to consider the zooming ratio in the photography industry. The image quality of a lens with a zooming ratio of less than three times was relatively good. For example, the zooming ratio of a 70 - 200mm lens was about 2.9, which was within three times, while the zooming ratio of a 70 - 300mm lens was greater than three times. For special shooting needs, if long-distance shots were often needed, such as shooting birds, taking photos in places such as the Kenyan grasslands, etc., lenses such as 100 - 400mm, 200 - 400mm, and 100 - 500mm were more suitable. In terms of brand and model, users of different brands had different recommendations. For Canon users, whether it was F2.8 or F4, they should buy lenses with IS (anti-shake function) as much as possible. If the budget is sufficient, you can choose Love Xiao-White Bunny; if the budget is limited, you can consider the second-hand Xiao-Xiaobai; if you are conflicted between Love Xiao-Xiaobai and Little White, you can choose according to the use and weight. Love Xiao-Xiaobai is lighter, so you can choose it if you take more photos. If you were to use the Eos R system, the RF70 - 200mm F4LIS USM was a good choice. It was shorter than the EP version and lighter. For Nikon users, the electromagnetic pulse cannon would be the priority. If the budget was not enough, the Tenglong lens could be considered. However, the SP 70 - 200mm F2.8 Di VCUSD G2 should be chosen. For the users of the company, I recommend the F70 - 200mm F2.8 GM OSS II. In addition, when choosing between the original PE 70 - 200mm F4G OSS and the Tenglong 70 - 180mm F2.8 Di III VXD, the original Sony-made lens had been on the market for a long time, and the performance under the F4 aperture was not much different from the performance under the Tenglong F2.8 aperture. Only the internal zoom had an advantage, so the Tenglong lens was more recommended. When comparing the 70 - 200mm and 100 - 400mm focal length lenses, the large aperture of 70 - 200mm was better than 100 - 400mm in low-light environments, and it was more suitable for shooting portraits and more suitable for scenes;100 - 400mm could be positioned as a landscape lens, which was also suitable for travel shooting, but the disadvantage was that it was larger in size and weight. If you want to expand the focal length, you can use a combination of 100 - 400mm +85mm fixed-focus or 70 - 200mm + distance-increasing lens. At the same time, factors such as the weight of the lens and its maneuverability should also be considered. For example, the 70 - 200mm F4 may be more suitable because the new models of various brands have optimized image quality and focus, and the lens is more portable than the F2.8 large aperture model with the same bayonet. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
