Fish-eye lenses are the most creative tools you can use to create striking images that can challenge convention. Never thought about including one in your equipment? Today we explain why owning a fish eye lens is a great idea, and how to get the most out of them on your shoots, no matter what the discipline.
Fish eye lenses: everything you need to know
On another occasion, we showed you 30 examples of great photos taken with fish eye lenses. If you look at them, you will definitely want one of these lenses in your equipment. It must be said that their possibilities are unlimited. When you are new to photography, the first attempt to get familiar with the camera is to take one with a standard lens, with a variable focal length between 18 and 55 mm.
These lenses are perfect for understanding the distances and compositions that can be used, but very quickly you specialize in one discipline rather than another, so you need to specialize your equipment. If you want to practice architectural or landscape photography, you will need a wide angle lens. If you want to photograph nature, birds or the moon, you will need a telephoto lens, while if you prefer portraits, you will need a lens with a focal length of 35 or 50 mm. But what happens when you want to get away from the seen and seen again work? Fish-eye lenses are a great alternative.
Characteristics of fish eye lenses
Unlike other lenses on the market, fish eye lenses are very easy to spot at a glance because they have a particularly curved and domed lens. This is because they can cover a much wider field of view than other lenses on the market, even more than wide angle lenses. In fact, fish eye lenses cover a 180º field of view and the resulting photos show details and information that would have been excluded from the field with another lens.
Focal length of fish eye lenses
This type of lens has focal lengths between 7 and 17 mm but there are exceptions. The fisheye lenses are therefore lenses that cause a more or less important distortion on the lines that compose the image. There are fisheye lenses with a field of view greater than 200º, so that a black frame or vignetting appears around the image, which makes it very creative.
This vignetting is also a consequence of using an APS-C or Full Frame sensor. For the latter type of sensor, as the full frame is larger, it reveals all the details of the lens and reveals this creative edge and characteristic of fisheye lenses.
