Olympus change lens recommendation
Here are some Olympus zoom lens recommendations: - Olympus 12 - 40mm Pro f2.8: This was the must-have lens in the M43 system, released in 2013. It was well-made and had an all-metal body. The zooming ring and focusing ring were just right, but it weighed 382g. In terms of image quality and sharpness, it still performed well on the Olympus EM10 third-generation body. During the day, the sharpness was better in indoor and outdoor environments with sufficient light, and at night and in dim environments, the large aperture of f2.8 could make up for the lack of high sensitivity of the M43 system. However, at the end of 2021, its price was still a little too high. - Olympus 150 - 400mm F4.5TC1.25x IS Pro: This lens has the longest equivalent focal length of 2000mm and the closest focusing distance of 1.3 meters. It covers 300 - 1000mm F4.5 - 5.6 focal lengths (including the focal length conversion factor of the M43 system 2x and the built-in 1.25x zoom lens). With the MC - 20 double zoom lens and the E-M1X body, it can achieve the equivalent of 2000mm F11 hand-held shooting. Its focusing speed was not slow, and with the camera's bird tracking function, it could better identify birds in complex environments. Whether it was shooting birds in the forest or other scenes, it was more practical. - Olympus M.ZUIKO Digital ED 40 - 150mm f/4 - 5.6R: It was a medium telephoto zoom lens that could be used for medium telephoto shooting needs. If the M43 was more portable, the 14 - 42 or 14 - 42 EZ electric zoom lens would be a better choice. Its sharpness and image quality were more conscientious. In addition, if you want to be portable and consider the price similar to the 12 - 40 Pro, you can try the 12 - 45 Pro. It is lighter and sharper, but the aperture is smaller.

Olympus lens news
Olympus has a variety of lenses. Here is some information about them: - 12 - 40mm Pro f2.8 lens: released in 2013. At the end of 2021, the second-hand price was around 2500 yuan. It was 80% to 90% new. It had an all-metal body and a solid feel. The zoom ring and focus ring were just right, but it weighed 382g. Its image quality and sharpness performance was good. On the Olympus EM10 third-generation body, the 100% zooming of the auto show photo center in the daytime indoor environment had a better image quality. The sharpness in the outdoor environment was similar to the helmet 14 - 42, 40 - 150, but it had the advantage of a large aperture of f2.8, which could make up for the lack of high sensitivity of the M43 at night and in dim environments. The quality could still be played after 8 years, but the price was a little high. - M.ZUIKO DIGITAL 17mm f/1.8 wide-angle lens (fixed focus): Micro 4/3 mount, priced at 2899 yuan. - M.ZUIKO DIGITAL ED 7 - 14mm f/2.8 Pro wide-angle lens (zoom): has a corresponding mount. - [M. ZDED12 - 50/3.5 - 6.3EZ lens: Although it is a "dog head" lens, it has a wide focal length coverage, with macro and wide-angle lenses. It costs more than 700 yuan second-hand and is cost-effective.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Jewelry shooting lens recommendation
In jewelry shooting, macro lenses were recommended. For example, Canon's EF100mm f/2.8L MCROIS USM or RF100mm f/2.8L MCROIS USM. Nikon and other brands also had similar macro lenses to choose from. The macro lens could capture the details of the accessory well and highlight the creativity of the designer. In addition, you can also use a conventional lens with a close-up lens to shoot. For example, a NiSi close-up lens with a 70 - 200mm and 24 - 105mm lens can also achieve a shooting effect close to a macro lens to a certain extent. At the same time, like the 60-million-pel portrait focus dual camera configuration on the front of the Huawei nova 13 Pro, it could be used perfectly from 0.7x to 5x zoom. It could also be used for close-up shooting of accessories, and some mobile phone lenses could also achieve good results when shooting accessories, especially for some jewelry shooting scenes that were not particularly demanding or needed to be quickly shot. The mobile phone lens could provide a convenient way to shoot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Beginner's micro-lens recommendation
Based on context alone For beginners, here are some recommendations for micro-lenses: ** 1. Fixed focus lens ** 1. ** 50mm fixed-focus lens (standard focal length)** - This kind of lens had a perspective that was close to the human eye's visual effect on a full-frame mini-photo. - A large aperture (such as f/1.8 or f/1.4) could create a shallow depth of field effect, blurring the background and making the subject more prominent, making it very suitable for portraits. - The price was relatively affordable and cost-effective. It was suitable for beginners to practice composition and master focusing techniques. 2. ** 35mm fixed-focus lens (small wide-angle focal length)** - On the full-frame micro-sheet, the 35mm lens had a wider angle of view, suitable for shooting environmental portraits, cultural documentary, and so on. - It could include more environmental elements in the picture, and at the same time, the character could get a better performance. - Some 35mm fixed-focus lenses had good optical quality, and they were small, light, and easy to carry. ** 2. Zooming lens ** 1. **18 - 55mm zoom lens (standard zoom lens)** - The focal length covered a wide range from wide-angle to medium-long focal length. It had a wide range of uses. - It could shoot scenery, portraits, buildings, and many other subjects. - It was usually the standard lens of many micro-single cameras. It was affordable and was used as a beginner lens to let the user understand the effects of different focal lengths. 2. **24 - 70mm zoom lens (common focal length)** - On the full-frame micro-sheet, this focal length was the focal length that many photographers used on a daily basis. - It can be used to shoot portraits, activities, and some landscapes. The quality is good and can meet certain professional needs. However, the price was higher than the 18 - 55mm lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It would include imaging tests and editor recommendation index, which would help novices easily find the products they needed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Pentax high sharpness lens recommendation
Here are some Pentax lens recommendations with high sharpness: - Pentax SmC501.7: This is an old film lens. It's exquisitely made and made of pure metal. It's heavy to hold in your hand. The lens is beautifully coated and has high sharpness. - HD Penntax-D FA 85mmF1.4ED SPD AW-lens: It uses three Super ED (ultra-low dispersion) glass optical elements to effectively reduce the color difference to a minimum. It also uses glass molded aspheric optical elements to compensate for spherical and comet aberrations. Even if the aperture was fully opened, it could provide ultra-clear, high-contrast images with extremely high sharpness. At a focusing distance of 4 meters, the distortion can be reduced to almost zero, providing clear, distortion-free images throughout the entire focusing range. - Pentax Pentax 17's 25mm f/3.5 lens: This lens is equivalent to a 37mm lens in the 35mm format (because it is a half-frame camera). It is based on the lens in the 1994 Espirio Mini and has been re-designed to support the half-frame format. After high-definition coating, it has been optimized for clarity and sharpness. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can I change the camera lens of my mobile phone?
The lens of a mobile phone was integrated into the main board. The thickness and structure of the mobile phone determined that the lens could not be replaced. However, with the development of technology, an external phone lens appeared. It did not replace the original phone lens, but superimposed a lens on the original lens. In addition, there were also some devices that tried to combine the camera lens with the phone. For example, the Switch lens allowed the phone to be fixed by the Mag Safe magnet, allowing the user to view the screen, control the camera functions, and so on. However, this was not directly changing the lens on the phone. Therefore, although the original lens of the mobile phone was generally not changeable, it could be expanded by connecting an external lens or a camera lens device. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the lens of the camera lens?
Based on context alone The lens of the camera lens was made up of many different types of lenses. This included a concave lens, which had a thick middle and thin edge structure. It had a converging effect on light, which helped to focus the light on the imaging plane, making the image clear. There were also concave lenses, which were thin in the middle and thick at the edges. They had a diffusing effect on light and were often used to correct aberrations. In addition, there were also aspheric lenses. These lenses were not the traditional spherical shape. They could better correct aberrations, improve image quality, and reduce image distortion and blurring. They were widely used in modern camera lenses. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon lens, Nikon lens
Canon lenses and Nikon lenses were well-known brands in the field of camera lenses. In terms of Nikon lenses, the new Z-mount lenses were generally of high quality, such as holo-field compatibility and excellent corner resolution. The F-mount was limited by the caliber and the distance between the two sides, while the Z-mount had a great improvement in this aspect, especially in the wide-angle to mid-focal length section. Canon lenses, such as the RF28 - 70mm F2.8 lens, had a constant large aperture of F2.8. It was portable, and the image quality was average, even a little beyond the positioning of the silver ring lens. It also had anti-shake function. However, its price was sometimes affected by marketing routines. For example, during the 11/11 period, the price of Canon RF28 - 70mm was higher than the recommended price on the official website and did not return to normal value. These two lenses had their own optical design features, advantages, and market positioning under different camera mount systems. <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>
