Range of use of different lenses

The optical lens could be categorized from the following different angles: 1. * * By Material **: - * * Glass lens **: composed of glass lenses. It has high requirements for molding technology, coating process, precision processing, etc. It has high light transmission and is not easy to age. It is mainly used in high-end imaging fields, such as single-lens reflex cameras, high-end scanner, high-end security video surveillance equipment, etc. - * * plastic lens **: It is mainly composed of plastic lenses. It has strong malleability and is easy to be made into an aspheric shape. It is also convenient for miniaturized processing and has low cost. It is widely used in the field of mobile phones and digital cameras, but the light transmission rate is lower than that of glass lenses. - * * Glass-plastic hybrid lens **: Composed of glass lens and plastic lens, combining the characteristics of the two, mainly used in surveillance cameras, vehicles and other fields. 2. * * By focal length **: - * * Short focal length lens **: suitable for close-up shots. Due to the small focal length, the image is not clear when shooting distant objects. - Medium focus lens: The image captured is close to the perspective seen by the human eye. - * * Telephoto lens **: The angle of view is small, but it can magnify distant objects. It is suitable for shooting distant objects, football games, wild animals, etc. 3. * * By field of view **: - * * Wide-angle lens **: The field of view is generally around 80 °. It is mainly used for shooting in general scenes. - * * Super wide-angle lens **: used to shoot scenes such as scenery, buildings, and group photos. - Fisheye lens: It is an extreme wide-angle lens with a field of view close to or even more than 180 °. The diameter of the lens is very short and bulges outward, similar to the eyes of a fish. It is widely used in scene monitoring, robot navigation, measurement, and other fields. 4. * * According to the change of focal length **: - * * Fixed focus lens **: - * * Fixed focal lens **: Mainly used in surveillance, micro-cameras, and vehicles. - * * Manual aperture circle focal lens **: Used for robot vision, road monitoring, etc. - * * Automatic Aperture Rifle Lenses **: They are widely used in places with complex lighting, such as surveillance cameras. - * * Zooming lens **: - * * Manual aperture zoom lens **. - * * Automatic aperture electric zoom lens **. - * * Electric triple variable lens (Aperture, focal length, and focus can all be changed)**. 5. * * By structure **: - * * Fixed aperture circle focal lens **. - * * Manual aperture circle focal lens **. - * * Automatic aperture circle focal lens **. - * * Manual zoom lens ** - * * Automatic zooming lens ** - * * Automatic aperture electric zoom lens **. - * * Electric triple-variable (Aperture, focal length, and focus can be changed) lens **. 6. * * By Origin **: - * * Japanese lens **: The color reproduction is better. - * * Germanic lens **: The layering is stronger. - [China Shot: The price is relatively low.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In the field of advertising photography, fixed-focus lenses were used because of their high resolution and contrast. The most common fixed-focus lens was Canon's 50mm F1.8 fixed-focus lens for a full-frame micro-camera. It was designed to fit into the Eos R series. The 43mm filter diameter made it easy to install a protective lens. The anti-shake function and autofocus system ensured that the image was stable in dark light or when shooting with a hand-held camera. There was also Canon's small spittoon 3rd generation ef501.8stm, which was specially designed for full-frame single-lens reflex cameras. When paired with Canon's Canon series body, it could show excellent wide-angle fixed-focus performance and background blurring effect brought by large aperture. The YONGN 50mm F1.8 autofocus lens could also be used for advertising photography. It was compatible with a variety of micro-single systems and continued the advantage of large aperture. In addition, 35mm, 50mm, 85mm, 200mm, etc. were also common fixed-focus lenses. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
