After the camera uses the wide-angle additional lens,
After the camera used the wide-angle additional lens, it would have some characteristics. From the perspective of the imaging principle, the objective lens used a concave lens, and the eyepieces used a concave lens to form an inverted telescope system. There was also a formula that could approximately calculate the focal length of the combined lens. However, the wide-angle lens was generally used for small DCs and home cameras. The image quality was poor and the distortion was more serious. It was basically an accessory that was better than nothing. For the vast majority of rigorous photography, it did not have much value. However, in some cases, the bottom fixed lens of the AI version of the fluorite C7 indoor pan/tilt camera used a 108° wide-angle lens with a focal length of [email protected], which could shoot a wider video image. If a wide-angle additional lens was used, the viewing angle could be further widened in theory, but the image quality and distortion should be paid attention to. Read more exciting novels for free
Wide-angle additional lens introduction
The wide-angle lens was an additional lens suitable for single-lens reflex cameras. In photography, wide-angle photography was mainly achieved through a wide-angle lens with a field of view of more than 45 degrees. For any frame, the focal length of the wide-angle lens was always shorter than the normal focal length. The image was smaller than the normal image, but it contained more scenes. The size of the scene was directly proportional to the length of the focal length, and the increase in the field of view coverage was inverse to the length of the focal length. The focal length mentioned by digital cameras was mostly equivalent focal length. From the perspective of photography, the smaller the focal length, the wider the field of view, and the wider the range of objects that could be accommodated; the larger the focal length, the narrower the field of view, and it could shoot distant objects. Most of the popular digital cameras on the market had a wide-angle focal length between 35 - 38mm. A true wide-angle digital camera was a product with a lens focal length that covered a 28mm wide-angle. The 28mm wide-angle field of view was 76 degrees, which was wider than the 62 degrees of 35mm. It could produce a unique visual effect and accommodate a wider scene. The wide-angle lens had many shooting features, such as being able to shoot a wide range, exaggerating the sense of distance, and having a wide focusing range. When using the wide-angle lens, it could magnify the object in front of you and shrink the object in the distance. The surrounding image was easily distorted, but it could adjust any point of the picture to the appropriate focal length, making the picture clearer, similar to full autofocus. It was suitable for taking photos of larger scenes, such as buildings and landscapes. The lens had a short focal length, wide angle of view, and deep field of view. Different types of cameras had different focal lengths and angles of view. With full-frame cameras as the standard, a wide-angle lens usually referred to a lens with a focal length between 24mm and 35mm, and the angle of view was between 84 degrees and 63 degrees. The wide-angle lens had an obvious perspective effect. It could exaggerate the close-up scene, reduce the distant scene, increase the depth of the picture, make the foregrounding elements more prominent, enhance the visual impact, and show the spatial relationship of the scene. However, the edge part was prone to barrel distortion, which was more obvious when shooting straight objects. However, a better lens would control the distortion in design, and the software could also correct it later. Due to the short focal length, it could provide a large depth of field even under a large aperture. It was suitable for shooting scenes that required a large range of clarity. It could capture more scenes in a limited space, which was especially important in indoor and architectural photography. It was also relatively light and convenient for travel and daily shooting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to adjust a Sonny camera with a wide-angle lens?
Aiya, you asked how to adjust a wide-angle lens on a Sonny camera. That would depend on what effect you wanted to achieve. Generally speaking, you can start with the basic parameters. For example, autofocus would be fine for scenery shots. Manual focus was also good for creative shots. As for the aperture, if you wanted the image to be clear, you had to adjust the aperture a little smaller and the value a little larger, like f8 or f11. He also had to pay attention to the shutter speed. If the light was good, the shutter speed could be faster. If the light was dim, the shutter speed could be slower. However, a slow shutter speed required a tripod, or the photo would be easily blurred. The light sensitivity could not be adjusted blindly. When there was enough light, the light sensitivity could be lowered to make the picture purer. When the light was not good, it could be increased appropriately, but not too high, or there would be a lot of noise. The white balance was also very important. It was adjusted according to the color temperature of the light so that the color of the screen looked normal. Of course, there might be some small differences between different Sony-camera models, but that was about it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The difference between wide-angle lens and super wide-angle lens
In the field of photography, there were the following differences between a wide-angle lens and a super wide-angle lens: 1. ** Focus and angle of view ** - [Wide-angle lens: Normal wide-angle lens has a focal length of 38 - 24mm and a viewing angle of 60 - 84 degrees.] - [Ultra-wide angle lens: focal length 20 - 13mm, angle of view 94 - 118 degrees. Ultra-wide angle lens has a very wide angle of view (between 80 - 110 degrees).] 2. ** Visual Effects ** - Wide-angle lens: wide angle of view, large depth of field, suitable for shooting long and panoramic images, can show open space and grand scenes, has distortion effect, reasonable use can present a unique visual effect, improper use will cause the image distortion; - Super wide-angle lens: Due to its wider angle of view, it can accommodate more elements when displaying grand scenes, and the distortion effect may be more obvious. It is more advantageous when shooting scenes that require a strong visual impact (such as grand buildings, wide natural landscapes, etc.). The wide-angle lens (reflective lens) mentioned in the field of transportation did not have the concept of a super wide-angle lens. The main emphasis here was on its functions such as expanding the field of vision and ensuring safety. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Super wide-angle lens, animals
The super wide-angle lens had many effects when shooting animals. It could take pictures of animals and their environment at the same time, making the picture more realistic. For example, when shooting a gibbon eating, it could not only take pictures of the gibbon eating leaves, but also cover its body and surrounding environment. When shooting a tiger swimming, it could include the water surface, the tiger and the bottom of the pool at once. When taking close-up photos of animals, such as the close-up photos of groundhogs, if the hardware configuration of the ultra-wide-angle lens was good, the fur color could be restored in place, and the details of the fur and beard could be clearly seen. At the same time, there would be no obvious over-exposure or over-darkness when shooting under indoor lighting. Moreover, when using the super wide-angle lens to shoot animals, even if the animal's face was taken at close range, the scenery behind it could be included in the picture, making the composition more interesting. When shooting a flamingo with long legs, it could also stretch the proportion of the animal in the picture and enhance the visual illusion. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Comparing the effects of a wide-angle lens and a normal lens
The wide-angle lens of the camera had many differences in effect compared to the ordinary lens: 1. ** View Range ** - Wide-angle lens: Generally, the focal length is below 35mm (24mm and below is a super wide-angle lens). It has a wide angle of view and can shoot more scenes. It is suitable for shooting vast scenery, large-scale activities, buildings, and other scenes. It can present a larger scene and a sense of space. - Ordinary shots: The angle of view is relatively narrow, and it focuses more on portraits or capturing details. It is not suitable for shooting large scenes, but focuses on the performance of a specific subject. 2. ** Picture tension and realism ** - [Wide-angle lens: When shooting, the picture may appear more tense and dynamic. Due to the wide angle of view, the picture elements are rich, creating a special visual effect.] - Normal lens: The image is more natural and realistic, closer to the effect of direct observation by the human eye. 3. ** Depth-of-field effect ** - Wide-angle lens: Usually has a strong depth of field effect, which can make the background and the background clear. It is very advantageous when shooting scenes that require overall clarity. - Normal lens: The depth of field is shallow, and it is easy to blur the background and highlight the main body. It is suitable for portraits and other shots that need to highlight a specific subject and weaken the background. 4. ** Distortion Effect ** - Wide-angle lens: There is a greater distortion. When shooting, pay attention to reducing the distortion by controlling the shooting angle, and avoid placing the main body at the edge of the picture to avoid distortion. - [Normal lens: Comparatively speaking, the distortion is small.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
