Espèces, Caractéristiques et principales applications des objectifs Fisheye ultra grand angle

An ultra-wide-angle Lentille de fisheye is a special wide-angle lens. Son angle de vision peut généralement atteindre 180 degrés ou plus, qui est plus large qu'un objectif ultra grand angle ordinaire. 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 Fisheye

The viewing angle of a panoramic fisheye lens reaches or exceeds 180 degrés, 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 degrés, 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

Vue d'ensemble pour objectif CCTV, the biggest feature of the ultra-wide-angle Lentille de fisheye 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 degrés, 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.

Distorsion effect

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 “oeil de poisson” La technologie et les produits de perception visuelle D ont été promus et appliqués dans de nombreux domaines tels que l'électronique grand public. This distortion effect can add a unique visual style and creativity to the image.

Vue d'ensemble pour objectif CCTV

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 lentilles fisheye 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. Donc, 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 photographie

The ultra-wide-angle fisheye lens can capture more elements in indoor environments, making the interior space appear more spacious and three-dimensional.

Creative photographie

The distortion characteristics of ultra-wide-angle lentilles fisheye can create a variety of interesting photo effects, making them ideal for creative photography.

Sports photographie

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.
