A fisheye lens is a lens with a focal length shorter than 16mm and an angle of view greater than 180°, and is often used to shoot a wide scene, especially in scenes that require exaggerated scene size and circular distortion. Here are some suggested environments for using action camera fisheye lenses:
Expansive natural scenery: Since fisheye lenses are capable of shooting ultra-wide angles, they are ideal for photographing natural scenery such as the sea, grasslands, mountains, etc.
Indoor gatherings and events: Fisheye lenses are capable of creating interesting distortion effects, so when shooting indoor gatherings or events, they can create very unique and interesting images.
Sporting events: Since fisheye lenses are able to capture expansive scenes, it is possible to capture the entire field and the movements of players when filming sporting events, such as football, basketball, etc.
Cityscape and architecture: Fisheye lenses are also great for photographing cityscapes and architecture, capturing the bustle of the city and the unique lines of architecture.
Creative shooting: Fisheye lenses are also suitable for creative shooting, such as macro, close-up, etc., due to their ability to produce circular distortion and exaggerated visual effects.
In summary, action camera fisheye lenses are suitable for shooting environments that require exaggerated scene size, circular distortion, or shooting large scenes. However, it should be noted that when shooting with fisheye lenses, you need to keep a certain distance to avoid overly exaggerated distortion effects.
