WIDE-ANGLE LENSES
Take a wider view
From landscapes to environmental portraits, harness the power of a wide lens to enhance the appeal and impact of your shots
A nything that gives a wider view than the human eye is considered a wide-angle lens in optical terms, because you are squeezing in more of the scene than you can see unaided. This means anything less than 50mm on a full-frame camera, or less than 35mm on an APS-C body. Extreme wide lenses such as fisheyes can show a 180-degree view, but most photographers prefer focal lengths between 16 and 35mm.
Most wide-angles distort the scene to some degree, typically with barrel distortion toward the edges; the wider you go, the more apparent this becomes. Some distortion can be corrected, but it’s essentially part of the wide-angle look.
