The Characteristics of Fisheye Lens and Suitable Scenes for Shooting

Ⅰ. What are fisheye lenses?

We all know that wide-angle lenses that are shorter than wide-angle lenses are ultra-wide-angle lenses, but what about ultra-wide-angle lenses that are shorter than ultra-wide-angle lenses? Fisheye lenses, sometimes called panoramic lenses, are ultra-wide-angle lenses having a shorter focal length and a bigger field of vision than regular ultra-wide-angle lenses. The focal length of a panoramic lens might be as short as 180 degrees or much broader. So how did they get the name fisheye lenses?

The focal length of fisheye lenses is often between 6mm and 16mm (the normal lens is roughly 50 mm). We believe that focal lengths between 6mm and 16mm will provide a distorted vision of the fisheye lenses, comparable to the shape and function of the fisheye, thus the name fisheye lenses.

Ⅱ. What distinguishes fisheye lenses from other types of lenses?

Fisheye lenses have a field of view of 180° or more, with some going as high as 230°, implying that the vision is particularly wide, and they keep the barrel distortion of the image to exaggerate the distortion effect so that all straight lines except the central part of the image become curved arcs. From 1 meter in front of the lens to infinity, the depth of focus is very vast, resulting in clear photos.

There are two primary varieties of fisheye lenses: circular fisheye lenses, which generate a circular image on the negative with the width of the negative as its diameter, and linear fisheye lenses, which produce a circular image on the negative with the width of the negative as its diameter. The diagonal fisheye lenses, on the other hand, generate a rectangular anamorphic picture that spans the whole width of the negative.

Ⅲ. What types of scenarios do fisheye lenses work well in?

Fisheye lenses were originally employed to analyze the composition of the sky and clouds in meteorology. Because of their distinctive characteristics, these lenses immediately gained prominence in the field of general photography. Fisheye lenses are great for capturing circular vistas like amphitheaters, panoramic views of squares, and the sky, among other things. Fisheye lenses provide a wide variety of images and can distort a scene's viewpoint, giving it a high, wide, expansive appearance. fisheye lenses, which were created for astronomical photography, are now frequently used to record enormous panoramas or create inventive special effects. They suffer from extreme barrel distortion, which may occasionally give the image a fascinating look. Fisheye lenses are frequently low-cost and may be utilized to record a variety of subjects.
