The Primus lens was a type of industrial lens. It had the following characteristics and advantages: 1. ** Large detection field of view and high-resolution double-sided remote design **: It is specially designed for 10-million-pel full-frame sensors. It has a large detection field of view and is suitable for precise measurement of size objects, such as size mobile phone screens, printed circuit boards, flat glass, engine components, air conditioner components, etc. 2. ** Precise adjustment of telocentricity **: The measurement results can be consistent at any working distance within the depth of field. 3. ** Ultra-low Distortion Design **: Increase the detection field of view while ensuring that the error of each field of view is within a very small range (without software distortion compensation). 4. ** Simple and stable structural design **: suitable for industrial environments under various conditions. 5. ** Image stability **: Its image amplification is not affected by the position of the object, nor does it change due to the change of the object distance. It has a high stability and has obvious advantages when measuring objects that are not in the same plane. 6. ** Large depth of field feature **: When observing objects with a certain thickness, the image contrast can still be maintained. The symmetrical nature of the optical system and the parallel nature of the beam improve the stability of the overall image and reduce the blurred noise. It increases the depth of field compared to ordinary industrial lenses. 7. ** Light source stability matching **: The matched visual light source can have better quality when shooting, such as LCD, textile or print quality control, and in the optical system, it can ensure that the light beam enters vertically and projects vertically onto the sensor chip to reduce measurement errors. The model number of Primus's large-field-of-view lens was VP -LVFM017 - 416 - 254 - M58. The interface was M58, and the working distance was 416mm. It supported a maximum sensor size of 35mm film, which was perfect for 4K and 8K front-line cameras. Read more exciting novels for free
There were many advantages to installing a wide-angle lens on a phone lens. From the perspective of the shooting effect, the wide-angle lens could expand the field of view of the camera, making the captured picture wider and grander. For example, it could cover more scenery elements when shooting scenery, and it could also shoot a larger and richer scene in a narrow space. In terms of portrait photography, it could make the person look thinner and more beautiful, and it could also expand the front and back scenes, allowing the picture to accommodate more content. For example, the situation where the feet could not be seen when taking a full-body photo could be improved. In terms of functions, some wide-angle lenses also had a macro function, which could be used to shoot close-up shots and other images with different needs. Some wide-angle lenses also had a fill light, which could provide lighting assistance in the case of insufficient light. Some even had the function of live beauty fill light, cold and warm seven-color dimming, which could help improve the image effect in live broadcasts and video shooting scenes. However, there may be some minor problems with installing a wide-angle lens. For example, it may affect the image quality of the original lens of the phone, and the effect of wide-angle lenses of different quality and price may vary greatly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It had the following advantages: 1. ** Light and portable **: It is the smallest and lightest APS-C frame constant F2.8 aperture zoom lens. The lens size is 72.2mm x 62.0mm and weighs about 270g (or 260g). The GM aspheric lens with a high index of refraction was used to shorten the overall length of the lens. The anti-slip surface of the lens made it comfortable to hold and difficult to slip off. 2. ** Good close-up effect **: The closest focusing distance is relatively short. The closest focusing distance at the 10mm end is 11.6cm, and the magnification can reach 1:4. It can capture the details of the object at a close distance. When taking a close-up shot, it could display a unique perspective effect. The main body was prominent, and the background was blurred. The large aperture of F2.8 enhanced the blurring ability. 3. ** Perfect for Vlog shooting **: It has a wide field of view and an equivalent focal length of 16 - 28.8mm (or 15 - 27mm). It can shoot rich images and include more scene elements. It has a constant F2.8 large aperture, excellent image quality, compact size, fast and quiet autofocus performance, and weak breathing effect. 4. ** Excellent Image Quality **: Using 3 FLD fluorite low-dispersion lenses, 1 SLD special low-dispersion lens, and 4 aspheric lenses to highly correct all kinds of aberrations, especially the prismatic coma, the image quality is significantly improved. 5. ** Good control of distortion, dispersion, and dark angle **: It can provide good composition at F2.8 in the entire zooming range.

It's possible that the theme of the novel is exploring the complexity of human relationships and the search for meaning in life. Maybe it focuses on how characters cope with changes and overcome obstacles.
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>
In landscape photography, the wide-angle fixed-focus lens had a unique advantage. From the focal length range, lenses between 24 - 35mm were considered wide-angle lenses, and 28mm focal lengths were more commonly used in landscape photography. The wide-angle fixed-focus lens could highlight the background and enhance the sense of space in the picture. Nikon's 14 - 24mm f/2.8G ED lens was the standard lens for architecture, scenery, and starry sky photographers. It could provide a wider angle of view. In landscape photography, 14mm and 17mm brought a big difference in the image effect, which was a good choice for photographers who pursued a wider angle of view. Canon's lens, the ts-e 17mm 4L lens, was the most widely available 135mm lens in the original factory. It also had special significance for landscape photography. However, there were some issues to be aware of when using a wide-angle lens. For example, an ultra-wide-angle lens (focal length below 24mm) might have perspective distortion and glare when shooting against light. Although this was a wide-angle fixed-focus lens, it was necessary to pay attention to similar issues to a certain extent to avoid these situations from negatively affecting the work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The super wide-angle lens had a multi-dimensional effect in tourism photography. In terms of composition elements, more elements could be included to make the picture more " comprehensive." This was more friendly to photographers who had composition choice confusion, but too many elements could lead to a messy picture and a lack of focus. For example, when shooting a big scene that contained many elements, all the elements would be included in the picture, which might make it seem like there was no distinction between primary and secondary. In terms of distortion control, it could highlight the majestic momentum of the picture. If the edge distortion was used well, it could enhance the expression. For example, when shooting a character, putting the limbs on the edge could produce the effect of long legs. However, if it was not used well, it would become a drawback. For example, if the face of the character was placed on the edge of the picture, it would be shot as a slanted " flat fatty." If the control was not good when shooting the building, it would make the building slanted. As for horizontal control, the inherent characteristics of the ultra-wide-angle lens made it difficult to control the horizon when shooting composition. It was easy to tilt the horizon when shooting with a hand, and the early process of shooting with a tripod was more cumbersome. In terms of depth of field performance, the super wide-angle lens was suitable for showing a large depth of field. It was almost impossible to shoot a shallow depth of field effect. If you wanted to have a deep and prominent feeling, you could only rely on reasonable composition. From the scope of use, the super wide-angle lens was not a " general use " type. The shooting subject was relatively limited, but it could show its unique charm when shooting scenery, architecture, and other subjects. For example, when shooting scenes such as extended corridors, spectacular buildings, and the internal structure of buildings, it could reflect the lens 'distortion control ability, color reproduction ability, special perspective relationship, and other advantages. It could also play a role in shooting special scenes such as the starry sky. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
