Old machine with new lens
There were many situations where old machines were matched with new lenses. From the perspective of the camera mount, if the camera mount did not change, for example, when Nikon transitioned from a single-lens reflex camera to a micro-lens reflex camera, the old F-mount single-lens reflex camera was still sold for a period of time, and the old machine could theoretically use the newly introduced F-mount compatible lens. Canon's EF-mount single-lens reflex cameras and new lenses were the same. As long as the bayonet was the same and the compatibility was not abandoned by the manufacturer, the old machine could be equipped with a new lens. However, when the bayonet changes, the situation will become complicated, such as Nikon from F-mount to Z-mount, Canon from ESF-M mount to RF-mount, etc. If you want to use the lens of the new bayonet on the old machine (old bayonet camera), you often need an interface ring, and there may be differences in functional compatibility, such as the autofocus function may be affected. In terms of imaging effects, even if an old machine was paired with a new lens, it might not be able to fully utilize the performance of the new lens. This was because the old machine's sensor resolution, image processing power, and other factors might limit the performance of the new lens. For example, some old machines had low sensor resolution, and even if the new lens had high resolution, it could not fully display its advantages. Moreover, the old machine might not be as advanced as the new machine in terms of color reproduction and distortion correction, resulting in the new lens not being able to produce the best imaging effect on the new machine.

Nikon old-fashioned single-lens reflex lens
Nikon's old-fashioned DSLR lens had many features. In terms of optical quality, some of the old lenses of Nikon DSLR had extremely high optical quality, such as the Nikon Nikkor 105mm f/2.5. Its design had been verified for a long time, and the lenses were polished and assembled carefully. Some of the materials used were more expensive than modern lenses, and special glasses such as thorium glass and lead glass, which were now no longer used, were used. This helped to provide a higher index of refraction, improve color difference control, and overall image quality. In terms of sharpness and color performance, it was not bad by today's standards. In terms of mechanical technology, the metal lens barrel and smooth focus ring of the old Nikon DSLR lens were different from the modern automatic lens made of plastic. It was more mechanical, and its texture, weight, and feel could give the photographer a retro film era feeling. In terms of adaptability, the old-fashioned lens of Nikon's DSLR could be perfectly combined with some current cameras, such as the Sony A7 series, the Fuji X-T series, and the Canon Eos R series. The electronic viewfinder of the mirrorless camera could enlarge the real-time view, making it easier to manually focus. Combined with the focus assist function, it greatly improved the experience of using it on digital cameras. However, for beginners, it was not recommended to use the old Nikon DSLR lens because the old lens had problems such as focusing stagnation and hesitation, although the accuracy was acceptable. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A century-old classic. lens
The lens of a famous lens brand was an aspheric lens. Its "Elmarit" series was used in the lenses of the screw lens, M lens, R lens, and S and TL system lenses. There were many classic lenses from the Canon, and the following was a partial introduction: - **Noctilux 50mm f/0.95asph (Night God)**: This is a famous lens from the world of Leicas. The latin name "Noctilux" is a combination of "Noct"(night) and "Lux"(light). It is said to have a 12% better light transmission than the human eye and has a good quality. It is a lens that shows off the muscles of Leicas and is known as the "Night God". It is more suitable for sweeping the streets and is mainly targeted at top photographers. - ** 35mm f/1.4 Summilux-M (aspheric)**: The lens number was 11873. Due to the use of two aspheric lenses, it was called "double aspheric". In the 1980s, the production of aspheric lenses was stopped due to the complicated manufacturing process and high cost. It was now defined as a collectible and was one of the facades of Liqiang. - ** Summiron 90mm f/2 (Big Head Nine)**: A product of the M3 era. The market is mainly the second version. Its size is larger than the 135. It is a larger lens of the Mirage. It is heavy and bulky, suitable for practicing hand-held stability. - ** Tele-Elmarit m90f/2.8v2 (Skinny 9)**: Small and light, once popular, but due to technical problems, it was easy to fog and there was no solution. Subsequently, the design was changed, and now basically all the ones circulating on the market fog. - ** Tele-Elmarit m90f/2.8v1 (Feijiu)**: Its size is larger than the first generation. Its advantage is that it is affordable, and its quality and production effect are better. - ** Summicro 35mm f/2 first generation (eight pieces of jade/eight pieces of sister)**: Small and beautiful appearance, composed of eight lenses, is a classic model of the lens of the Canon, the beginning of the "Mei" family, the price is higher. - ** First generation Summilux-M 35mmF1.4 (Steel Mouth, Holy Light)**: It was praised as the lens with the best workmanship by the Canon. It was also the lens with the most complicated craftsmanship and the most extravagant workmanship among the 135 cameras. When there was sufficient light and the aperture was fully opened (this was also the case for the early shots of F2), the edges of the captured objects or characters would have a halo like holy light. - "<strong></strong></strong><strong>"<strong></strong></strong><strong></strong> - ** The first version of the Super Angulon 21mm f/4 (Super Angulon)**: designed by Schneider and recognized as the most tasteful 21mm lens.

The new lens in stock is gray
If there was dust on the new lenses in stock, it could have been produced during production, assembly, transportation, or storage. The analysis of the iPhone 15 lens dust problem can be used as a reference. The lens dust may be caused by the camera module's dust-proof measures during production, or by external impact during transportation and use, or by changes in temperature. Judging from the reason for the dust entering the lens of general optical equipment, the original parts of the manufacturer may have fine dust during production. For the zoom lens, the bellows effect of the internal lens moving back and forth during zooming would suck in a small amount of external dust, and the mechanical friction movement inside the lens would also produce debris. In the case of new lenses with dust in stock, for commercial sales, this may affect the sales and quality image of the product. It should be handled according to specific sales policies and quality control standards, such as cleaning, testing, or returning the gray lens. If the consumer found that the new lens in stock was gray, they could ask the merchant to deal with it according to the relevant purchase agreement and after-sales policy. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon's new machine
Canon's new machine was the G4891 automatic double-sided printer. It was a printer designed for the family. It was small and simple, easy to install, and size only 41.6*36.3*21.2cm. The buttons were concentrated around the screen and marked. The functions were integrated on the 2.7-inch color touch screen. The touch screen responded quickly and the operation was intuitive and convenient. The assembly steps were simple. The two print heads and four bottles of ink were assembled to the corresponding positions through the screen process and connected to Wi-Fi. The ink port had a dust cover, and the installation position of the print head was divided by numbers. The ink chamber was designed to be visualized to see the remaining ink. It supported a variety of paper size and media printing. In addition to the traditional connection with the computer, it could also be connected through the mobile phone Wi-Fi to support the 2.4 and 5 gigs Wi-Fi environments. You can use Canon Print APP or Canon Cloud Print Weixin Mini Programs to bind and print. There was also the soon-to-be-released EOS C80 movie projector, which was equipped with a 26-million-pel full-frame back-illuminated stacked image sensor. It had three native isos, i.e., 800\3200\12800, and could record 6K30p Cinema RAW video. It also had a second-generation full-pel dual-core focusing system and dual SD card slots. It was estimated to sell for only 5499 US dollars. In addition, there were recent rumors that Canon would release three new models next year, two of which would use full-frame sensors and the other would use APS-C format sensors. One of the two full-frame models might have a retro look, and the other might be the long-rumored high-resolution model (there were rumors that Canon was testing a 102-million-pel full-frame sensor, which might be used on this model). The new model with the APS-C frame sensor would focus more on video capture. On July 17th, the company released the Canon R1 and the Canon R5 Mark ll. The R1 was the Canon's flagship micro-camera. It improved the system functions such as focusing, continuous shooting, and transmission on the basis of the R3. It retained more than 24 million pixels and carried out various supplementary solutions. It added functions such as pre-shooting, motion priority, and in-camera noise reduction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Nikon old manual fixed-focus lens recommended
Here are some recommendations for Nikon's old manual fixed-focus lenses: - Scenery theme: From 8mm/16mm/20mm/24mm/28mm to 35mm, there are old Nikon fixed-focus lenses to choose from. - [Portrait theme: You can choose from 50/85/105/135/200 fixed-focus lenses ranging from 50mm to 200mm, and large aperture lenses ranging from F1.4 to F4.] - "Eco theme: 55mm/F2.8, 105mm/F2.8, 200mm/F4 for macro; 200mm/F2.8, 300mm/F2.8, 400mm/F2.8 for telephoto. - From a version perspective, Nikon's old lenses, from the STAR to the K version, from AI to AIs, all had good fixed-focus lenses to choose from, and you could give priority to choosing a large-aperture fixed-focus lens. For example, among all the 85/1.4 (including F/1.2) fixed-focus lenses, the Ai-S851. 4 was relatively cheap. Its lens body was made of metal and felt extremely sturdy. It still felt reliable after many years of use, but it was inconvenient to focus on a DSLR (this was not the lens itself, but the camera). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the lens of the camera lens?
Based on context alone The lens of the camera lens was made up of many different types of lenses. This included a concave lens, which had a thick middle and thin edge structure. It had a converging effect on light, which helped to focus the light on the imaging plane, making the image clear. There were also concave lenses, which were thin in the middle and thick at the edges. They had a diffusing effect on light and were often used to correct aberrations. In addition, there were also aspheric lenses. These lenses were not the traditional spherical shape. They could better correct aberrations, improve image quality, and reduce image distortion and blurring. They were widely used in modern camera lenses. <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>
