![]() ![]() See also: Depth of Field in Photography.This is especially useful for landscape photography, though can be problematic for isolating a subject from the background. Photo by: 'Pxhere'.ĭue to this large depth of field and the ability to reach infinity at a close distance, images that you take with a fisheye lens will appear to be sharp and in-focus from the foreground all the way through to the background. While you may still get a little bit of blur, you likely won't be able to achieve total bokeh.įisheye lenses have a large depth of field. This is the case even when you open up the aperture, for example to f/2.8 or f/4. See also: Understanding Focal Lengths in Landscape PhotographyĪs fisheye lenses have a short focal length, shooting with a smaller aperture such as f/16 will yield a very large depth of field.There are also fisheye lenses made specifically for cameras with APS-C sensors to produce a similar effect, such as the Tokina 10-17mm f/3.5-4.5 fisheye. Some fisheye lenses, like the Canon 8-15mm f/4L fisheye, cover a large focal range and are compatible with both full frame and crop sensor cameras. Some fisheye lenses cover a large focal range and are great for getting up close to the action. They can come as prime lenses (with a fixed focal length) or zoom lenses (with a variable focal range). Typical fisheye lenses have an ultra-wide focal length of around 24mm or less.

There are two types of fisheye lenses – those which are circular and those that are full-frame. However, the curved distortion effect is what makes a fisheye lens so unique and which separates it from a ‘rectilinear lens’ – that is, one that produces images whereby straight features appear to be straight.Īn example of a circular fisheye effect. What we usually want when we use a wide angle lens is to have straight lines appear to be straight. In fact, when reviewing lenses, distortion is often described as a flaw of the lens and not a characteristic that is desirable. The majority of the time, this is not an effect that photographers will want to achieve when taking a photograph. This is where straight lines around the centre of the frame appear to curve. The reason that you’ll experience this strong visual distortion is that due to the unique shape of their optics, fisheye lenses are affected by what is known as ‘curvilinear barrel distortion’. ![]() Wood, an American physicist and inventor who likened the effect of a fisheye lens to the world-view of a fish underwater.įisheye lenses create a strong visual distortion. Its name was first coined in 1906 by Robert W.
