Here are some ways to identify Canon lenses: - Check the lens number. If it was on the metal ring on the butt, it was 100% a parallel product. Since 2018, Canon's new lens number had been changed to the back of the lens instead of the rear butt. - Check the packaging box of the lens. If there was no round label that said " This is a genuine Canon sold in China and enjoy Canon's regular after-sales service ", it might be a parallel import. The mainstream goods generally had this label and were not opened. - For second-hand lenses, it was necessary to check whether the three sizes were one, that is, the number on the box, the number on the guarantee card, and the number on the body had to be consistent. If they were inconsistent, they might be parallel goods. - Check if the outer packaging is sealed with the original manufacturer's seal. Parallel goods usually do not have a seal. - Check if there are any hidden problems, including whether there are traces of use, scratches, or other damages on the surface of the lens. Open the various covers to check if there are any old marks or scars on the inside, because some merchants will replace the seal without destroying the integrity of the seal. - Call Canon's official website to confirm. - Check whether the accessories are original, because the body may be a legitimate product, but the accessories such as batteries and charger are domestic counterfeit. - Check the receipt and the guarantee card, etc., confirm whether the receipt provided by the seller is a regular machine-printed receipt, and check the guarantee card, product manual, and other service certificates.

Moreover, the user thought that the rental shop's DSLR was frequently used, aged quickly, and prone to problems. As for the lens, when it was returned, it was found that there were scratches on the lens. Although the user thought that it was not caused by himself, because he did not notice it on the spot when he signed for it, the merchant determined that it was the buyer's responsibility. However, there were also users who rented Canon 5D4 + 70 - 300 lenses from Taobao. They had a good experience, including good imaging, accurate focusing, and good customer service. Therefore, in general, the reliability of Canon DSLR lenses rented by Taobao was uncertain. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The lens was one of the core components of the optical imaging system. It was a key component of optical instruments such as cameras, video cameras, and telescopes. It was composed of lenses, mirrors, filter, and other optical components, which could change the direction of light transmission, focus light, filter light, etc. Its role was to convert the target object into an image through the optical imaging system and pass it to the receiver (such as camera sensor, human eye, etc.) for recording or observation. Cameras were also known as computer cameras, computer eyes, electronic eyes, and so on. They were a type of video input device. Just like human eyes, they could record and store the real environment they saw in the form of data. They had basic functions such as video recording and still image capture. After it collected the image (light signal) through the lens, the image was processed by the sensor circuit and control component in the camera and converted into a digital signal that the computer could recognize. Then, it was input into the computer through a parallel port or USB connection, and the image was restored by software. The main components of the camera are the lens, image sensor, pre-amplifier, ADC (automatic gain control), and A/D. It consists of a synchronous signal generator, a LCD driver, an image signal forming circuit, a D/A conversion circuit, and a power supply circuit. The optical image generated by the lens was projected onto the surface of the image sensor, and then converted into an electrical signal. After A/D (ADC) conversion, it became a digital image signal, which was then sent to the digital signal processing chip for processing. Then, it was transmitted to the computer through the USB interface for processing, and the image could be seen through the display. In the field of camera manufacturing, the airtightness of the lens was a vital indicator. It was directly related to the image quality and service life of the lens. There were technical difficulties in the airtightness test, such as the selection and precision requirements of the airtight instrument, the design of the lens tool and sealing tool, the training of the operator, the operating procedures, and the appearance protection. Different types of cameras had different features and functions. For example, Glory's hand-picked Xiao Pai smart camera Pro was equipped with three high-resolution lenses, supported cable network and dual-band Wifi, had a larger monitoring range, dual-screen monitoring, real-time tracking, 330-degree horizontal and 100-degree vertical adjustment, supported up to 20x hybrid optical zoom, had two types of fill light at night, supported multiple detection modes, and had a two-way voice call function. There was also a dual-lens camera that could rotate 360° without dead angles, and a fixed camera position to achieve remote alarm. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Bright Moon lenses had ordinary aspheric lenses, but there were also other types of lenses.
