Fisheye lens is a special kind of ultra-wide-angle lens. Generally, the angle of view is close to or equal to 180 °. Nikon even introduced fisheye lens with more than 180 degrees and up to 220 degrees. Because the images taken are very similar to those seen by fish, they are called fisheye lenses. Most fisheye lenses are generally short focal lengths, and most are fixed-focus lenses, and only a few are zoom lenses.
Type of fisheye lens
Fisheye lenses are roughly divided into two types, one is called Circular Fisheye, and the other is called Full Frame Fisheye. The circular fisheye is a fisheye lens, and the imaging circle used to capture the image is round, 180 degrees from any point on the sideline to the opposite side.
In contrast, full-frame fisheye is more common. The captured image is square, and the diagonal angle is 180 degrees.
In addition, there are also variable fisheye lenses on the market with a viewing angle of approximately 100 to 180 degrees. But in fact, only the widest end is a 180-degree fisheye effect.
Features of fisheye lens
The shooting range of the fisheye lens is very large, which can greatly exaggerate the perspective of the scene. Some people even think of it as a wide-angle lens with extremely poor distortion control. However, this feature can sometimes make the picture look interesting.
There are many choices of fisheye glasses on the market, such as:
Sigma AF 4.5mm f / 2.8 EX DC Circular HSM
Sigma AF 10mm f / 2.8 EX DC HSM
Sigma AF 15mm f / 2.8 EX DG Diagonal
