When choosing a DSLR lens for travel, the main consideration was its lightness and whether it could meet the shooting needs. The following types of shots can be used for reference: 1. ** Large zoom lens **: If you don't pursue the ultimate image quality and focus on traveling or sweeping the streets, you can consider lenses such as 28 - 200mm and Z24 - 200mm. The advantage of this type of lens was that the long focal length could capture some scenes that mobile phones could not capture. It could achieve the world in one shot and save the trouble of changing lenses outdoors. For example, the Nikon Z24 - 200mm F4 - 6.3 was priced at 5799 yuan, covering wide-angle to telephoto. The center image quality was good, but the edges were weak. It was worth buying for Nikon users who only had one camera and one lens. The overall weight was only 570g, and it was relatively light for daily street sweeping and traveling. Tenglong 28 - 200mm F2.8 - 5.6E mount, priced at 5088 yuan, with full focal length coverage, basically able to meet all kinds of shooting needs. It was more important to be able to shoot well than to shoot well during travel, and reducing the weight burden could also increase the enthusiasm of outdoor shooting. 2. **70 - 200mm telephoto lens **: This focal length has a very high production rate. The telephoto lens is not only suitable for travel, but also unique in shooting scenery, culture and other subjects. If you were stuck between F2.8 and F4, you could choose F4 if you wanted it to be light, F2.8 if you wanted picture quality, and consider a sub-factory lens if you didn't have enough budget. For example, the SonyFE70 - 200mm F2.8GM OSS II, priced at 17099 yuan and weighed 1045 grams. It was a second-generation product. Compared to the first-generation, it was nearly 30% lighter. The focusing speed was significantly improved, and the dispersion and glare control were excellent. The Sony70 - 200mm F4 Macro G OSS II was priced at 9599 yuan. Its size was reduced by about 15% compared to the previous generation. Its weight was reduced by about 46g, only 974g, and its length was shortened to 149mm. It adopted an external zoom design, which was light and compact. It had high image quality and high resolution. When the aperture was fully opened, the image quality from the center to the edge was very good. The focusing ability was improved and the macro function was added. It also optimized the breathing effect for video shooting. 3. ** Super Horizon Mirror **: For users who feel that 200mm is not enough, manufacturers have introduced some 28 - 400mm, 50 - 300mm, or 50 - 400mm lenses to meet the market demand in the past two years. It is suitable for photography users who pursue lightness and don't want to bring too many lenses. It is a good choice for landscape photography and street sweeping scenes. For example, the Nikon Z28 - 400mm F4 - 8 VR was priced at 9399 yuan. It was very convenient for travel enthusiasts. It was much lighter than the 70 - 200mm and 50 - 400mm. It was only 725g, and the overall quality and sharpness of the lens were passable. Tenglong 50 - 300mm F4.5 - 6.3E mount, priced at 5890 yuan. It was relatively popular recently and basically needed to be pre-sold before delivery. The overall picture quality was not bad. The 665g weight felt lighter to the hand. It supported the anti-shake function of the VC. The closest focusing distance of the 50mm end was 0.22m, and the magnification was 1:2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the DSLR lens is loose, you can consider the following solutions: 1. For low-end lenses, it was normal for them to be slightly loose because of the poor tolerance control due to cost issues. However, if the focus ring is loose, it is abnormal to cause the focus drift; if the zoom ring is loose, it may be a normal assembly problem; if the bayonet or lens is loose, it should be sent for repair. In addition, large zooming heads such as the 24 - 240 or 18 - 200 would have some lens zooming rings that could not be locked due to the heavy lens, which was normal. 2. If a part on the slide was loose, causing the moving parts to not move when zooming, you could try to fix the loose part. 3. You can drill a small hole no larger than 1mm at the appropriate position on the side of the lens cover, fold a thin line through the small hole, and then cut off the anti-loss rope with the small dot through the thin line. However, this method was a temporary emergency measure, and it was necessary to be careful when operating to avoid damage to the lens. 4. If the bayonet was loose due to aging, one or two strips of paper could be placed in the bayonet and the lens could be stuck in. If the bayonet cracked due to aging, a new bayonet would need to be replaced. 5. If the contact between the lens and the camera is not good, the display shows "Communication with the lens is faulty, please clean the lens contact". You can take off the lens and wipe the contact between the lens and the camera with a soft cloth or an eraser. If the bayonet is dirtied or damaged by electric shock, you can wipe the contact with alcohol. If it still does not work properly, it is recommended to send it to the repair station for treatment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some recommendations for landscape lenses: ** 1. Wide-angle zoom lens ** 1. ** Nikon AFZoom-Nikkor 16 - 35mm (similar focal length)** - This type of lens was used more frequently in landscape photography. It could provide an imaging range that was far beyond the human eye's field of vision and was suitable for imaging vast landscapes. The depth of field was long, which ensured that the scenes before and after the subject could be clearly reproduced on the screen. It also had exaggerated perspective distortion, which could bring a greater visual impact. - In terms of aperture selection, F4 aperture was completely sufficient for simple landscape photography to ensure sufficient depth of field. However, if you wanted to take into account the starry sky, you could consider a 16 - 35mm F2.8 zoom lens with a large aperture. 2. ** Canon EF15 - 35F2.8L IS USM (similar focal length)** - This was a super wide-angle lens with excellent image quality and good optical performance. Its wide-angle end was 1mm wider, and the viewing angle was increased to 110°. It was designed with a non-bulb structure, 82 filter size, reduced cost, weighed 840g, and had good anti-glare performance. The optical image stabilization could achieve 1/2 second hand-held shooting. ** 2. Telephoto zoom lens ** 1. ** Nikon AFZoom-Nikkor 75 - 300mm f/4.5 - 5.6** - This type of 70 - 200mm and 100 - 400mm telephoto zoom lens was suitable for shooting scenery. The advantage of a telephoto lens was that it could compress the space and make it easier to highlight the subject. For example, the focal length of 75 - 300mm could make the composition extremely flexible when shooting vast scenes such as mountains and grasslands. It could also have a good effect when shooting sunrise and sunset, and it was easy to shoot unique picture effects. 2. ** Nikon AFZoom-Nikkor 80 - 200mm f/2.8D ED (Small Cannon)** - It could also be used for landscape photography. The focal length of 80 - 200mm could provide a certain telescope effect when shooting scenery. It could help to intercept the desired part of the vast landscape, and it could compress the space to highlight the main body or show a unique picture level. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Among the domestic lenses, there were some 100-yuan half-frame large aperture portrait lenses to choose from, such as Vizos 56mm f1.7, Ming Craftsman 56mm f1.8, Yongnuo 50mm f1.8, Meike 55f1.4, etc. However, there was no more information to show their overall performance ranking among the DSLR lenses.

Here are a few Canon DSLR macro lens recommendations: 1. ** Canon EF100mm f/2.8L IS USM macro lens **: - In terms of price, the reference price was 7199 yuan, and the second-hand reference price was 3000 - 3800 yuan. - It had double IS optical image stabilization. It was good in terms of sharpness and out-of-focus performance. The autofocus speed was ideal for macro shooting, and it could take into account portrait shooting. It was still popular in the second-hand market during the shooting season. 2. ** Canon ESF-S 60mm f/2.8 USM macro lens **: - This was an APS-C frame macro lens, priced at 5500 yuan. Its focal length was equivalent to a 35mm camera focal length of about 96mm, and the imaging effect was very close to a 100mm macro lens under full frame. - The lens structure consisted of 8 groups of 12 lenses, with 3 groups of floating focusing mechanisms. When focusing, 2 - 4 groups would move according to different trajectories. This design could effectively compensate for a variety of aberrations to ensure high quality. It uses an internal focusing method, so the length of the lens body will not increase when shooting, and because of the USM ultrasonic motor, it can achieve full-time manual focusing. 3. ** Canon MP-E 65mm f/2.8 1 - 5X macro lens **: Price: 8499 yuan, it is a fixed-focus macro lens. 4. Canon EF50mm f/2.5 macro lens: 2495 yuan, but it has been stopped. 5. ** Canon TS-E 135mm f/4L macro lens **: Price: 14688 yuan. This is a shift-axis macro lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
For example, the original lens was usually more exquisite, with the Sony-branded logo clearly visible, and the interface part was more compact without any edges. Although the performance of the lens was good, the logo might not be too conspicuous or there might be some differences in craftsmanship. In addition, the original lens was often more secure in terms of image quality and after-sales service. However, there were many counterfeit goods on the market now. When buying, it was best to go to the official channels or the official website to ensure the quality. You could also use the MTF diagram of the lens to assist in the judgment. The higher the curve on the diagram, the better the quality of the lens. However, different lines represented different things and did not require too much memory. At the same time, the camera needed to be tested to check the resolution, sharpness, and the image quality of the dark parts. This part depended on the quality of the lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Pentax's Third Princess DSLR lenses referred to the FA 31mm F1.8AL Limited, FA 43mm F1.9 Limited, and FA 77mm F1.8 Limited. They were limited edition lenses, available in silver and black. They were small and exquisitely made. This statement was first put forward by the "Eye of the Wind" on the forum "Pentax135 lens godhood list---Joking about the P family's production lens group", and then widely spread in the Chinese world. In terms of optical performance, for example, the FA 43mm F1.9 Limited, as the earliest lens launched, was the "eldest princess" of the "three princesses." Its focal length met the definition of a standard lens, and the entire metal lens body was well-made. The image at the largest aperture was softer. After the aperture was reduced by two stops, the sharpness of the center and edge increased. The image was rich in layers, and the colors were fresh but not bright. It had a unique charm in portrait and landscape photography. The HD versions of these three lenses released by Ricoh (HD Pentax-FA 31mm F1.8 Limited, HD Pentax-FA 43mm F1.9 Limited, and HD Pentax-FA 77mm F1.8 Limited) adopted the HD multi-layer coating design, which could effectively suppress ghostly images or glare. The circular aperture design made the bokeh more gentle and natural. The surface of the lens was treated with SP anti-pollution coating, which made the anti-pollution characteristics better. In terms of price, the recommended price of the HD Pentax-FA 31mm was $1050, the recommended price of the HD Pentax-FA 43mm was $600, and the recommended price of the HD Pentax-FA 77mm was $800. The black version started with 0000001, and the silver version started with 1000001. However, in the era of digital single-lens reflex, due to Pentax's focus problems, these three lenses might run out of focus on the Pentax single-lens reflex body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It would include imaging tests and editor recommendation index, which would help novices easily find the products they needed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon DSLR lens zooming abnormalities could be caused by a variety of reasons: 1. ** Low battery **: Check if the battery is fully charged. Sometimes, the lens malfunction is due to the low battery. You can try to replace the battery. 2. ** Soft reset required **: In some cases, a soft reset of the Canon camera can solve the lens malfunction. 3. ** Mechanical Failure **: If the camera is dropped or squeezed, it may cause problems with mechanical parts such as the motor or gears, causing a jam. He could try to turn the camera lens down and shake it slightly to see if it could be removed by itself. If the battery is reinstalled or tried to be replaced, it is recommended to send it to the place where the camera is specially repaired for inspection. 4. ** Inappropriate use **: If the camera has been used for a long time, the lens may be out of service. You can consider replacing it. In addition, the focal length of the Canon camera's zoom rotating lens did not change. If it could not be rotated, it might be because the camera had been dropped or the lens was rotated with unreasonable force when using the camera. If the lens was rotated very tightly or could not be rotated, then the camera should be sent to the maintenance department for inspection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
