In terms of Canon's telephoto lens, Sima had some telephoto lenses to choose from. For example, Sima 150 - 600 could be used to shoot birds and chase stars. Tenglong also had a lens with a wide zoom range, but the imaging quality was quite different from Canon's lens. In addition, the AF50 - 200mm F4 - 5.6 DC-OS HSM from SIGMAR was a sub-factory lens with anti-shake and motor. For daily landscape and portrait double repair small zoom lenses, the Sima 18 - 35f/1.8 could also be considered. However, in different scenes, it was necessary to choose whether to use the sub-factory lens according to actual needs (such as imaging quality, economic factors, etc.).

Some of the lenses under the brands of Sima and Tenglong can be recommended as Canon's sub-factory lenses. Tamron was the first to introduce the APS-C format large aperture super wide-angle zoom lens 11 - 20mm F2.8, while Sima was the first to install the previously popular six APS-C lenses on the radio frequency mount. Some of the lenses under brands such as Sima and Tenglong were comparable to Canon's original lenses in terms of image quality and functions. They had a higher cost-performance ratio, but Canon's original lenses had more advantages in terms of stability and compatibility. The sub-factory lenses might have problems such as inaccurate focus, color deviation, stuck focus, and slow focus. Moreover, they were usually not as reliable as the original lenses in terms of maintenance and after-sales service. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A telephoto lens was a type of photographic lens that had a longer focal length than a standard lens. It could capture scenes and details from a distance and create unique visual effects. Telephoto lenses were divided into two types: ordinary telephoto lenses and super telephoto lenses. The focal length of an ordinary telephoto lens was close to that of a standard lens, while the focal length of an ultra-telephoto lens was far greater than that of a standard lens. The telephoto lens was suitable for shooting scenery, sports, close-ups, and other topics. It had a unique charm. Some mobile phones were also equipped with telephoto lenses that could zoom in and simplify the background, making it suitable for shooting distant objects and buildings. The use of a telephoto lens required attention to the problem of shaking, which could be solved by using a tripod or a stable support. When choosing a telephoto lens, factors such as focal length, anti-shake function, and optical performance needed to be considered.

Telephoto lenses and macro lenses had their own advantages and disadvantages. The choice of lens depended on the shooting requirements and the shooting environment. The focal length of a telephoto lens was longer than a standard lens. Usually, a telephoto lens was between 135mm and 300mm. It could be divided into ordinary telephoto lenses (85mm-300mm) and super telephoto lenses (300mm and above). It was suitable for shooting long-distance scenes or subjects, such as wild animals, people, urban landscapes, or mountain views. It could blur the background and background to strengthen the subject, and could also be used for close-ups or to highlight the difference in size. In terms of macro shooting, the telephoto lens could shoot small objects at a certain distance to avoid disturbing the subject, such as insects or wild animals. The background blurring effect was obvious and the details were strong. However, telephoto lenses usually had a small aperture, high light requirements, and high hand-held stability requirements, which made them prone to shaking. The macro lens was specially used to shoot small objects at a close distance. It could make the subject occupy the entire picture, and the details were very prominent. It could capture the fine details of the object at close range, and it could highlight the main object by adjusting the depth of field when shooting. However, the working distance of the macro lens was short, which might disturb the subject or block the light. The background control was relatively difficult, and the background blurring effect was relatively weak. If you often shoot long-distance objects or want to shoot macro without getting close to small objects (such as shooting insects that are not easy to approach), a telephoto lens is more suitable. If you focus on shooting small objects at close range to show extreme detail, a macro lens is more suitable. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
