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>
Canon lens parameters
Canon lenses had many parameters: ** 1. Type of bayonet ** 1. **EF** - It can be used directly on Canon's Canon's Canon 'Canon's Canon' Canon 2. **EF - S** - Canon's APS-C frame DSLR lens could not be directly installed on a full-frame DSLR. It could be used on the Eos-M series micro-lens and the Eos-R full-frame micro-lens through the transfer ring. 3. **EF - M** - Canon's Canon 'Canon's Canon's Canon 4. **RF** - Canon's Canon 5. **MP - E** - For macro photography, only MP-E 65mm f/2.81 - 5x. 6. **TS - E** - The electronic control shifted the lens. ** 2. Focus ** - The focal length in the lens model was the physical focal length. Standing in the same position, a small focal length meant a wide field of view, and a large focal length meant a good range of vision. For non-full-frame cameras, the actual use may need to consider the equivalent factor conversion according to the camera model. For example, the focal length range of the lens was 70 - 200mm, the angle of view at the 70mm end was relatively narrow, and the telescope ability at the 200mm end was better. ** 3. Maximum aperture ** 1. ** Permanent Aperture ** - For example,"f/2.8" could be set to this aperture value over the entire focal length range. For example, the EF70 - 200mm f/2.8 lens was a constant aperture lens. 2. ** Floating Aperture ** - Two numbers like "f/3.5 - 5.6" indicated that the maximum aperture changed over the entire focal length range. ** 4. Screen Level Identification ** - **L (Luxury) logo ** - It would only appear in Canon's professional lens identification information. It was the logo of the top Canon civilian lens. These lenses usually had a red decorative ring on the front end (red circle head). ** 5. Function ID ** 1. **IS (Image Stabilizer)** - This type of lens was equipped with Canon's unique image stabilizing device, which could offset the image blurring caused by hand shaking within a certain range. It was commonly used in Canon's high-end professional lenses. 2. **USM (ultrasonic motor)** - The lens using USM technology could achieve silent and fast-response autofocus. It was divided into three types: micro, ring, and NANO. There was also the STMs (Stepping Focus Machines), which were divided into two types: gear type and lead screw type. 3. **AL (Aspherical lens)** - It showed that the lens was designed with aspheric lenses to reduce the number of lenses. While reducing the weight and volume, it could provide better optical performance. It could solve the glare and edge distortion problems in wide-angle and zoom lenses, and it could also improve the optical quality of telephoto lenses. 4. **DO (Diffraction Optics)** - Lenses marked with this logo were equipped with multi-layered diffusing optical lenses, which had the characteristics of both fluorite and aspheric lenses. They were generally high-end Canon lenses. 5. ** DPS (a coating technology that optimized bokeh)** - It was commonly used in some Canon lenses to enhance the bokeh effect. 6. ** S-ud (S-ud glass) and UD (UD glass)** - The optical performance of S-KD glass was close to that of fluorite. The effect of one S-KD lens was equivalent to that of one fluorite lens, and the effect of two KD lenses was equivalent to that of one fluorite lens. These labels indicated that the lenses used the corresponding glass lenses. 7. **EMD (Electromagnetic Aperture)** - Lenses with this technology could open and close the aperture by electronic control. 8. **Float (Floating Function)** - When shooting at close range, the floating lens would compensate for the aberrations at close range to obtain better image quality. 9. ** CP (Focus Preset)** - It was Canon's high-end professional lens logo. The focus preset function allowed the lens to remember a certain focus distance. After setting the distance, the lens could automatically return to the set focus distance. This focus recovery function was even effective in manual focus mode. 10. ** ft-m (full-time manual)** - Canon lenses were equipped with full-time manual operation. The focus of the lens could be adjusted manually in the AF-mode. 11. ** Marco/macro ** - It means that the camera has a strong close-up ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon lens repair

Canon camera lens
In Canon lenses, the half-frame lens was a golden circle 17mm-55mm F2.8 lens. There are many red circle lenses in the common lens of the full frame, such as 24mm-70mm F4, 24mm-105mm F2.8, 24mm-105mm F4, 70mm-200mm F4, 100mm-400mm (golden circle), 70mm-300mm f.(The specific parameters after the aperture are not specified), etc. Among them, 70 - 200mm F2.8 is also regarded as the lens of the Emperor of Mirrors. These lenses had excellent performance in their respective focal lengths and application scenarios, such as excellent image quality and focal length adaptability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon lens and Nikon lens interface differences
Canon lenses mainly had the lens mount, which was Canon's full-frame single-lens reflex camera mount, as well as the lens mount, such as the ESF-S mount, the ESF-M mount, and the lens mount. Nikon lenses mainly had the lens mount, such as the F-mount, and the Z-mount. Their bayonet types were different, and their size, the distance between the two sides, the number and location of electronic contacts, and other parameters were also different. These differences determined the compatibility between the lens and the body, as well as the realization of functions. For example, Canon's RF-mount and Nikon's Z-mount were large-caliber mounts, but there were still differences in specific size and other characteristics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
