Can I still buy a DSLR lens with the cover off?

For beginners who want to buy an DSLR lens, here are some recommendations: - If the budget was limited, you could consider a 50mm F1.8 lens, such as Canon's EF50mmF1.8SM and Nikon's AF50mmF1.8D. They were affordable and had excellent optical quality, making them ideal choices for professional photography. - For beginners who were preparing to shoot different subjects such as landscape, portrait, macro, etc., they could refer to the relevant manuals. This kind of manual would recommend suitable lens products and matching solutions for each focal length (fisheye, wide-angle, medium-focal, telephoto). It would also introduce more classic lens combinations and techniques for lens application in these subjects. 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>

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>

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>

Canon's 5-axis anti-shake system in the Canon Eos R5/R6 could be used with the lens of the Canon Canon For example, an RF28 - 70mm f/2L lens without anti-shake could reach 8-speed anti-shake with the Eos R5/R6, and a Canon RF50mm f/1.2L USM lens without anti-shake could reach 7-speed anti-shake with these two cameras. In addition, some lenses could achieve at least 6th gear and above with the combination of the Eos R5/R6. When using the lens mount on the Eos M-series, be sure to use it with a full-frame lens. However, when using the EP lens, the video captured by the OS R series could not be corrected for distortion, and when using the EP lens, the OS R5/R6 could not achieve the best anti-shake performance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some recommendations for DSLR telephoto lenses: - Canon EF70 - 200mm f/2.8L IS II USM second-generation anti-shake rabbit, suitable for telephoto telephoto, priced at 9800 yuan. - If you are looking for a lightweight, portable, and don't have enough strength to hold a heavy lens for a long time, you can consider the 70 - 200mm F4. The new model has improved in terms of image quality and focus. Compared to the old bayonet, it is significantly slimmer. Compared to the new bayonet F2.8 large aperture model, it is more portable. - Tenglong 70 - 180mm F2.8G2 and Sima 70 - 200mm F2.8 were also available, but the original lens was much better than the sub-factory lens in terms of value preservation. - If the budget was around 1500, you could consider the Canon 18 - 200 lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The inspection of the DSLR lens can be carried out in the following aspects: 1. ** Appearance ** - ** Lenses Inspection **: Slightly tilt the front and back ends of the lens to a bright spot, observe the reflected light on the surface of the lens from the side, and check if there is any slight scratch on the coating layer. At the same time, observe from all angles of light and backlighting, and use a light source to carefully check if there is any obvious trauma on the front and back lenses. In addition, when selecting second-hand lenses, a small amount of oil or traces of use were normal, but the lenses needed to be checked. - ** Mirror body stability **: Check whether the lens is loose. The ruler lines, numbers, and letters on the lens barrel and adjustment ring should be clear and beautiful regardless of whether they are directly printed or concave. - ** Aperture lever **: Check the aperture lever to ensure that the aperture is opened and closed normally without any stagnation. 2. ** Function ** - ** Zooming and focusing ring test **: Turn the zooming ring and focusing ring. Under normal circumstances, the rotation should be light and uniform. - ** Manual Focus Test **: Turn the focus ring slowly and observe whether the focus ruler in the focus window is bi-directional synchronized. Then, turn the focus ring quickly to check whether it is synchronized. If it is not synchronized, there will be a problem if the focus ring needs to be rotated quickly to focus. - ** autofocus test **: After installing the lens, cover the lens with your hand and press the shutter halfway. Under normal circumstances, the lens 'focus scale will go from infinity to the closest focus distance and then back to infinity. If there is a stutter, a shake, or a manual focus ring rotation, it is abnormal. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
