What is an ultra wide angle lens and what is an ultra wide angle lens used for?

Lenses with a particularly wide range of angles.

Wide-angle lens. It is a lens with a focal length shorter than a standard lens, a viewing angle greater than a standard lens, and a distance longer than a fisheye lens.

A photographic lens with a smaller angle of view than a fisheye lens.

There are two types of lenses: ordinary wide-angle lenses and ultra-wide-angle lenses. The focal length of the 135 camera ordinary wide-angle lens is generally 38-24 mm, and the angle of view is 60-84 degrees; The ultra-wide-angle lens has a focal length of 20-13 mm and a viewing angle of 94-118 degrees. Due to the short focal length and large angle of view of the wide-angle lens, it is possible to capture a large area of scenery in a short shooting distance.

Therefore, it is widely used in the shooting of large-scale style photography.

The ultra-wide-angle lens will say that he can still have all the pictures left in this lens, that is, his angle of view is very wide, which is what it means, when he usually shoots the lens, he says that the part he sees is a small part of the current one.

The ultra-wide-angle lens actually means that the shooting range is relatively wide, and it is still relatively clear under a relatively large shooting range, which is called an ultra-wide-angle lens.

Zhao Guang's lens lens can take this ** position wider, and then the scenery will be bigger and better-looking.

The ultra-wide-angle lens can be pulled a little more than the original shooting angle.

The ultra-wide-angle lens is a lens that can cover angles and cover a large area, which is now equipped with many high-end mobile phones.

guǎng jiǎo jìng tóu is a type of lens with a wider angle of view and a shorter focal length than a general lens, and is often used to shoot scenes with a large area.

The so-called ultra-wide-angle lens is actually what people call a fisheye lens, that is, he can basically achieve 270-degree photography.

The ultra-wide-angle lens is that this lens can fit a little more than the picture of a normal lens, and it looks like the foot is very wide.

It's an ultra-wide-angle lens, and if it's an ultra-wide-angle lens, it's supposed to be a different lens from what we usually shoot, so you can search for it on the Internet!

The ultra-wide-angle lens is the kind of lens that can shoot a large range and the largest range, and it is a lens that we commonly use to shoot the kind of combined photos.

The ultra-wide-angle lens should greatly broaden the field of view, and when recording, it can record a wider field of view.

The design of the improvisation of the branches is very good, and it can play a wide range of characters, so everyone likes to use this lens very much.

Lenses with focal lengths of less than 20mm are generally referred to as ultra-wide-angle lenses. The ultra-wide-angle lens has a wide angle of view and stunning expressiveness, especially suitable for shooting landscapes and architecture.

What is an ultra-wide-angle lens? Generally speaking, the lens is a long-range lens on the camera, or some national lenses, and the country at most refers to the angle of more than 5 times or some other more than 10 times can be multiplied as a wide-angle lens.

The so-called ultra-wide-angle lens refers to the fact that the mobile phone we use now can shoot in the same lens when taking pictures, and a very large angle can shoot from our left to the right, for example.

A wide-angle camera is an all-round camera that can be illuminated from anywhere.

The ultra-wide-angle lens is a means of shooting, and the requirements for the camera are very strict, and professional photographic equipment can be completed to shoot through the bird lens.

Ultra-wide-angle lens is a lens with a particularly wide angle of view (80-110 degrees) in the wide-angle lens. On 35mm cameras, mostly refer to 15-20mm lenses.

The ultra-wide-angle lens has a wide field of view, and unlike the fisheye lens, which has strong distortion, it is a lens that eliminates distortion very well.

It is an ultra-wide-angle lens, that is, the angle seen in his lens is very large, and the wide is called an ultra-wide-angle lens.

It's boring, the lens is turned on or your camera captures the ** will be in a big state, but things will be compressed.

In the case of an ultra-wide-angle lens, this lens is an ultra-wide-angle lens composed of a very wide angle, so it is said to be one.

The ultra-wide-angle lens is a sharper, higher quality, and longer shooting distance.

It is an ultra-wide-angle lens, and of course it can be photographed even with a lens that is beyond the wide-angle angle.

In general, the lens of Super Barefoot is very clear, and its overall sense of a picture is very strong.

Actually, I think the ultra-wide-angle lens is an animation shot from different perspectives or something similar.

Among wide-angle lenses, lenses with a particularly wide range of angles of view (80-110 degrees) are called so. On 35mm cameras, mostly refer to 15-20mm lenses.

Hyper Wide—Angle Lens, the ultra-wide-angle lens has a wide field of view, and unlike the fisheye lens, which has strong distortion, it is a lens that eliminates distortion very well.

The so-called ultra-wide-angle lens is actually a type of wide-angle lens.

SuperWide-angle lens. The usefulness of shooting is to shoot a wider field of view.

The basic characteristics of a wide-angle lens are a large angle of view and a wide field of view. The range of things that can be observed from a single viewpoint is much larger than what the human eye sees at the same viewpoint; Depth of field.

long, can exhibit a considerable range of clarity; It can emphasize the perspective effect of the picture, and is good at exaggerating the foreground and expressing the sense of distance and proximity of the scene, which is conducive to enhancing the appeal of the picture.

Shooting examples. 1. Photograph landscapes.

2. Take portraits.

If you use a wide-angle lens for portraits, you can place the hands and feet of the portrait slightly on the edge of the photo, which can make the portrait more slender, and the wide-angle lens can shoot portraits with a sense of space**, unlike using a telephoto lens.

3. Travel shooting.

If you want to reduce the distortion of the lens, zoom the wide-angle lens to the telephoto (e.g. the 35mm end of 16-35mm) and move the subject away from the edge of the photo.

It is possible to shoot larger scenes, and under the same lens, shoot more content.

An ultra-wide-angle lens is a photographic lens with a shorter focal length than a standard lens, a larger angle of view than a standard lens, a longer distance than a fisheye lens, and a smaller angle of view than a fisheye lens.

Take Nikon Nikkor Z 14-30mm F 4 S as an example, which means that a lens with a particularly wide range of viewing angles needs to reach 80 110 degrees to be called an ultra-wide-angle lens.

Features of an ultra-wide-angle lens

1. When shooting with the maximum aperture, it is easy to have obvious "vignetting". These reefs gradually change from the deepest black to the middle, which is the "lomo" effect in many retouching app filters on mobile phones, which can better guide the line of sight and achieve the effect of highlighting the subject. If you want to remove this vignetting, make the aperture as small as possible in the early stage of the shooting, and the vignetting will be reduced.

2. The depth of field is very large, even if you shoot with the largest aperture, the scenery in the picture scene from near to far is basically clear.

3. The perspective is serious, and the distortion effect of "near large and far small" is conducive to creating an exaggerated picture effect. Try to avoid straight lines in the picture when shooting landscape photos in the early stage, and if you are shooting buildings, you can't avoid lines no matter what, and you can also process them in PS in the later stage.

A wide-angle lens is a type of photographic lens. A wide-angle lens has a shorter focal length than a standard lens and a wider angle of view than the human eye. In general, a 35mm camera has a wide-angle lens focal length of 28 mm to 35 mm and a field of view between 76 and 64 degrees.

The wide-angle lens has a wide field of view and a long depth of field, making it suitable for general snap-shot and general landscape photography. If the focal length range is 15 mm to 24 mm and the angle of view is between 110 degrees and 84 degrees, it is an ultra-wide-angle lens. Those close to or even greater than 180 degree angles are fisheye lenses.

Lens features:

The most criticized aspect of wide-angle lenses and ultra-wide-angle lenses is their severe barrel distortion, or negative distortion. The image of a square object becomes a four corners that shrink inward, and the middle of the edge line protrudes outwards like a barrel, hence the name barrel deformation.

The reason for the distortion is that the distance between the imaging point and the optical axis is different, and the lateral magnification is also different due to the different bending ability of the lens to the color light, and the result is that there is an aberration between the actual image and the ideal image.

For example, if you take a group photo, the faces of the people standing on both sides will be uncontrollably deformed. People can use photoshop and other image drawing software to make simple corrections to make up for the distortion problem somewhat.

In contrast to the distortion of the barrel of the wide-angle lens, pincushion distortion or positive distortion may occur at the telephoto end of the telephoto lens or zoom lens, and the image of a square object will become concave on all sides, with the four corners protruding like a pillow.

The exception is the 16mm Hologon lens from ZEISS, which has a wide 110-degree viewing angle but no distortion at all. The widest-angle anamorphic lens is a 12mm F Zero-D lens from Venus Optics with a 122° angle of view.
