Типы, Особенности и основные области применения сверхширокоугольных объективов «рыбий глаз»
An ultra-wide-angle объектив рыбий глаз is a special wide-angle lens. Угол обзора обычно может достигать 180 градусов или выше, что шире обычного сверхширокоугольного объектива. It is widely used in the field of photography and videography and can capture a very broad scene.
1、Types of ultra-wide-angle fisheye lenses
There are two main types of ultra-wide-angle fisheye lenses: panoramic fisheye and circular fisheye.
Panoramic жisheye
The viewing angle of a panoramic fisheye lens reaches or exceeds 180 градусов, which can capture almost all scenes in the picture and present an extremely wide field of view. The image of a panoramic fisheye lens will have a significant curved effect, which is different from the straight viewing angle seen by the human eye.
Round fisheye
The viewing angle of a circular fisheye lens is usually 180 градусов, which can capture a complete circular picture. The image of a circular fisheye shows a circular border with a certain black edge at its edge.

2、Features of ultra-wide-angle fisheye lenses
Как подсказывает название, the biggest feature of the ultra-wide-angle объектив рыбий глаз is its ultra-wide angle. Let’s take a closer look at the main features:
Great viewing angle
The viewing angle of an ultra-wide-angle fisheye lens is generally above 180 градусов, which can capture very wide scenes and give the picture a strong sense of space and three-dimensionality.
High perspective effect
The ultra-wide-angle fisheye lens can capture close-up details of the subject while pulling the background further away, highlighting the subject and enhancing the sense of perspective.
Искажение еffect
Due to the special design of the lens, the ultra-wide-angle fisheye lens will produce obvious distortion, which will cause the edges of the picture to be significantly deformed, forming a “рыбий глаз” эффект. This distortion effect can add a unique visual style and creativity to the image.
Большая глубина резкости
Ultra-wide-angle fisheye lenses usually have a large depth of field, which can present clear details of both the foreground and background in the picture.

Small size and weight
Compared with other lenses of the same focal length, ultra-wide-angle линзы «рыбий глаз» are usually smaller in size and weight, making them more portable.
Extreme close-up
Due to its wide field of view and special perspective distortion effect, the ultra-wide-angle fisheye lens can capture large areas of scenes at very close distances. Поэтому, it is very effective when shooting indoors, crowded places, or in scenes where the sense of close distance needs to be emphasized.
3、The main applications of ultra-wide-angle fisheye lenses
Ultra-wide-angle fisheye lenses are widely used in photography and videography due to their large viewing angle and unique distortion effect. The following are some of their main applications:
Scenery photography
The ultra-wide-angle fisheye lens can capture a broad scene and is ideal for photographing natural scenery and urban architecture.
Indoor пхотография
The ultra-wide-angle fisheye lens can capture more elements in indoor environments, making the interior space appear more spacious and three-dimensional.
Сreative пхотография
The distortion characteristics of ultra-wide-angle линзы «рыбий глаз» can create a variety of interesting photo effects, making them ideal for creative photography.

Sports пхотография
The ultra-wide-angle fisheye lens can capture a wider range when shooting sports scenes, making the sports pictures more dynamic and shocking.
It should be noted that photographers should carefully choose the subjects and scenes when using an ultra-wide-angle fisheye lens to ensure that its characteristics can be fully utilized, and pay attention to controlling distortion and distortion problems to obtain better works.
