Taking the Tenglong 28 - 75mm lens as an example, the model A036 28 - 75mm F/2.8Di III RXD released in 2018 was the first generation product. In 2021, the second generation product 28 - 75mm F/2.8Di III VXD G2 (model A063) was developed on the basis of the first generation product. The second-generation product had improved in terms of image quality and resolution, close-up performance, design, AF-mode speed, and custom functions. In terms of image quality, the optical system was re-designed, and the image from the center of the picture to the edge of the full-focus segment was sharp. In terms of close-up performance, the nearest shooting distance at the wide-angle end was shortened from 0.19m to 0.18m, and the maximum photography ratio was increased from 1:2.9 to 1:2.7. In terms of appearance, metal parts were added inside the zoom ring and the focusing ring, and the outer surface was newly painted, which made it difficult to scratch and leave fingerprints. The handling performance and appearance texture were improved. The AF-speed was about twice that of the original product. The lens could also be customized with various functions through dedicated software. Read more exciting novels for free

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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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>

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>
