This effect is also known as a “full-frame fisheye” effect because the resulting image covers the entire frame.įull-frame camera + 8mm = Circular fisheyeĮOS 5D Mark III/ EF8-15mm f/4L Fisheye USM / FL: 8mm/ Aperture-priority AE (f/4, 1/3200 sec, EV+0.7)/ ISO 200/ WB: Auto It is obtained at a focal length of around 15mm on a full-frame camera, and 10mm on an APS-C camera. On the other hand, a diagonal fisheye effect captures a roughly 180-degree diagonal angle-of-view and a greatly distorted view of the image periphery.

However, on an APS-C camera, you will not be able to obtain a distinctive circular fisheye effect even if you shot at 8mm because your actual 35mm film equivalent focal length would be 13mm. You can get a circular fisheye effect at a focal length of around 8mm when using a fisheye lens on a full-frame camera. Vignetting occurs in the corners of the image frame, which results in a “tunnel vision” effect where the scene seems to be contained within a round circle. The circular fisheye effect gives a 180-degree angle of view across the whole periphery (horizontally, vertically, and diagonally) with a barrel-like distortion.

The type of fisheye effect actually achievable depends on your camera sensor size. There are two types of fisheye effects that can be obtained using fisheye lenses: circular fisheye and diagonal fisheye. (Reported by: Teppei Kohno)ĮOS 5D Mark III/ EF8-15mm f/4L Fisheye USM / FL: 15mm/ Aperture-priority AE (f/11, 1/320 sec, EV-0.3)/ ISO 400/ WB: AutoĬircular fisheye v.s diagonal fisheye effectsĪ fisheye lens lets you capture an overwhelmingly wider range of a scene in front of you compared to a wide-angle lens. Here, we learn about the two types of fisheye lens effects and how your camera sensor size and focal length affect your fisheye image. They can capture photos with a 180-degree range, which lets you achieve photos with a greatly distorted periphery. Fisheye lenses are specialized lenses characterised by their ability to capture an overwhelmingly wider range than wide-angle lenses.
