The Rokinon 8mm f/3.5 HD is a great example. Like the GoPro, most action cameras also feature built-in wide fish-eye lenses. They cram in as much information as possible. They have a distinctive, hemispherical type of lens distortion. They are at the bottom of the scale in terms of focal length. Their angle of view is usually 180 degrees, letting you see half of a full rotation. Fish-Eye Wide-Angle Lensįish-eye lenses are special ultra-wide-angle lenses. We differentiate between three main sorts of wide-angle lenses in terms of distortion. What Are the Three Main Types of Wide-Angle Lenses? If you want to know how these translate to your camera, divide them by 1.5 for APS-C cameras or two for Micro Four Thirds cameras. This results in a tighter field of view.įor simplification, all focal lengths mentioned here are full-frame camera equivalents. The camera that you use influences how your lens’s view will “look.” Smaller camera sensors crop out the center portion of any lens. The widest lenses on the market are 10mm (rectilinear lenses) and 8mm (fish-eye lenses).īut we have to make a disclaimer here. Most kit or standard zoom lenses go down to 24mm or 28mm. The most popular wide-angle zoom range is 16-35mm. Focal lengths below 16mm are considered ultra-wide angles. Between 24mm to 16mm is what we usually refer to when saying wide angle. But there’s still a lot of room for further specifications.įocal lengths between 35mm and 24mm are considered standard wide angles. How Wide Is a Wide-Angle Lens?Īs I mentioned, a wide angle means anything below 35mm (by popular definition). The mirrorless equivalent would be the Canon RF 15-35mm f/2.8L USM. The Canon EF 16-35mm f/2.8 III lens is an excellent example of a professional wide-angle zoom lens. A zoom lens is a jack of all trades, a master of none. Prime lenses usually surpass a zoom lens’s image quality in the same price range. They are often quite small, but they come with serious compromises. But a zoom lens is generally heavier and more expensive due to extra mechanisms and glass inside the lens. Zoom lenses are versatile, letting you keep your gear to a minimum. Most zoom lenses are more specific, giving you one or two of these. Some all-around zoom travel lens options cover wide, standard, and telephoto focal lengths. The Canon 24mm f/2.8 STM is a great example of a small and cheap prime lens.Ī zoom lens has a variable focal length (zoom range). Primes are generally lighter, faster, cheaper, and produce better image quality. A prime lens has a fixed focal length, meaning you can change your field of view by moving closer or further away. Does a Wide-Angle Lens Zoom?Īll lenses, including wide-angle lenses, come as either a prime or a zoom version. This is roughly 63 degrees of a diagonal field of view. So what focal lengths (in mm) can be considered a wide angle? The popular definition is that a lens below or equivalent to 35mm is considered a wide-angle lens. But this doesn’t translate directly to millimeters (mm) and degrees. First, we must clarify the meaning of “wide angle.” The most common description is that a wide-angle lens displays a wider field of view than our vision.
