Canon s5is lens malfunction problem
Canon S5IS lens may have a fault where the aperture cable is broken. The fault phenomenon is that, except for the sports mode, the display will turn black when the shutter is pressed halfway. Although the sports mode will not turn black, it will automatically change to a small aperture and a large IS. The shutter is also very fast, and the imaging effect is very poor. The video recording is normal, and the manual adjustment of the aperture and shutter value in M mode is ineffective. When the shutter is pressed halfway, it will turn dark. The cause of the malfunction might be a problem with the aperture drive circuit, causing the aperture to be unable to adjust its size according to the light measurement results. If you encounter similar problems, you can check the lens cable. Read more exciting novels for free
Canon lens contact malfunction repair price
Canon lens contact failure repair prices vary due to a variety of factors. If it was a common reason such as a broken cable, the repair price of Canon customer service in Beijing Jinbao Street was about 300 yuan. If the 24 - 70 2.8 generation lens cable was broken, it would cost more than ten yuan to buy the cable and about 150 yuan to find someone to replace it.

Canon scan malfunction
When Canon's scanner reported "computer failure or busy", it was necessary to unplug the power of the printer, wait for about 10 seconds, then plug it in, and then scan again, because once the printer had an alarm, it needed to be removed to work normally. If the above operation is still not effective, open the host computer connected to the printer, open the auxiliary software of the driver software (usually [Multifunction Machine]), open it, select the first scanning function, click to the multi-function scanning page, and then click [Reader] to scan successfully. When the above methods are ineffective, you need to re-install the printer driver. In addition, the frequent problems with the printer were generally due to the frequent power on and off of the host connected to the computer, which had a great impact on the driver. Therefore, it was recommended to equip a separate printer host. <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>
Canon composite machine internal malfunction
If it was a problem with the Canon 2530i digital composite machine's document feed, for example, when the document feed was copying, it always indicated that there was a paper jam, but there was actually no paper jam. After lifting the upper cover of the document feed, another page could be fed, and then the paper jam would appear again. For copiers and printing machines, the paper jam was usually caused by the dirty or damaged paper feed detection sensor or the detection lever not being reset. If the sensor was damaged, it should be shown when the paper feed started. However, the possibility of the sensor being damaged was not high. It could be caused by the sensor detection lever not being fully reset or the sensor being dirty. However, several sensors and detection lever of the document Feeder were blocked by the cover of the lower draft table, so they could not be seen clearly. If the maintenance manual of the machine could not find the method to disassemble and replace the document Feeder, it might be necessary to disassemble the document Feeder for inspection. If it is a fixing-related fault, codes such as E000 fixing temperature rise fault, E001 0001 main fixing over-temperature, E001 0002 sub-fixing over-temperature, E001 0003 fixing over-temperature, E002 abnormal pre-heating, E003 abnormal pre-heating, E004 0001 fixing lamp SSR short circuit, E004 0002 fixing lamp power relay abnormal fixing lamp power relay continuous ON, E005 fixing cleaning web paper fault motor fault, etc. may appear.

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>
