About Fish Eye lenses

Fish eye lenses are a unique type of lens that provide a wide-angle view of the world, with a curved distortion that creates a spherical or hemispherical image. This type of lens is particularly popular among photographers and videographers who want to capture immersive, panoramic shots of landscapes, architecture, and other subjects.

Fish-eye lenses are named after the way they mimic the visual perspective of a fish, with a wide field of view that captures everything in its path. The lens is designed to create an image that is circular or semi-circular, depending on the specific lens used. This effect is achieved by bending light through a curved glass element that creates a distortion in the image.

One of the most significant benefits of fish-eye lenses is their ability to capture a wide-angle view of the world. Unlike traditional lenses, which have a narrow field of view, lenses can capture everything within a 180-degree angle. This makes them ideal for capturing landscapes, cityscapes, and other large-scale scenes that require a broad perspective.

Another benefit of this lenses is their ability to create unique and visually striking images. The distortion created by the lens creates a spherical or hemispherical image that can add depth and interest to a photograph or video. This effect is particularly effective when used to capture architecture or other geometric shapes, as the distortion can create interesting patterns and shapes.

Fish-eye lenses are also useful in low-light conditions, as they have a wider aperture than traditional lenses. This allows them to capture more light, resulting in brighter, clearer images even in challenging lighting conditions. This makes them a popular choice for night photography and astrophotography, where capturing as much light as possible is essential.

There are two main types of fish-eye lenses: circular and full-frame. Circular fish eye lenses create a circular image with a black border surrounding the central image. This effect is created because the lens captures more of the image than the camera’s sensor can process, resulting in the circular image. Full-frame lenses, on the other hand, fill the entire camera frame with the fish-eye image, resulting in a semi-circular or hemispherical image.

Fish eye lenses come in a range of focal lengths, with some lenses offering more extreme distortion than others. Some FE lenses, for example, have a focal length of 8mm, while others have a focal length of 16mm. The focal length of the lens affects the degree of distortion in the image, with shorter focal lengths resulting in more distortion.

When using this lens, it’s important to be aware of the distortion created by the lens. While this distortion can be a creative tool, it can also be overwhelming or distracting in some situations. For example, using a fish-eye lens to capture a portrait may result in a distorted, unflattering image of the subject. It’s important to consider the subject and the intended use of the image when choosing whether to use a fish-eye lens.

In conclusion, fish eye lenses are a unique and powerful tool for photographers and videographers. They offer a wide-angle view of the world with a distinctive distortion that can add depth and interest to an image. While they may not be suitable for all situations, they can be a valuable addition to any photographer’s toolkit. Whether used to capture landscapes, cityscapes, architecture, or other subjects, lenses offer a fresh perspective on the world around us.
