A fisheye lens is an extreme ultra-wide-angle lens that typically has the following characteristics:
Large field of view: The field of view of fisheye lenses can generally reach 220° or 230°, which allows it to shoot a wide range of scenes at close range.
Strong perspective: When shooting close to the subject, a fisheye lens can create a very strong perspective effect, emphasizing the contrast between the near and the far and the small, resulting in a stunning image.
Special Imaging Methods: Fisheye lenses have two different imaging methods, one that fills the entire frame, and the other that presents a circular image, both of which are accompanied by a considerable degree of distortion and a strong sense of perspective convergence.
Here are some tips for using fisheye lenses for photography:
Use foreground to create visual impact: Choosing an interesting foreground can produce powerful visual effects.
Master the depth of field: The depth of field of fisheye lenses can extend from a few centimeters to infinity, and when used wisely, you can create unique images.
Composition techniques: Try to place the subject in the center of the frame to reduce distortion, or choose a multi-line and easily recognizable scene to the edges to enhance the distortion effect.
Observe the edges of the viewfinder: Keep an eye on the edges of the viewfinder while shooting to prevent unwanted objects from being ingested into the lens and affecting the final artistic effect.
In addition, fisheye lenses play an important role in safety supervision, national defense and military, pipeline testing and weather forecasting due to their large field of view and full-time information acquisition capabilities.
Overall, fisheye lenses are an interesting choice in photography to capture unusual images and are also indispensable in the professional field.
