Focal length and distortion

WebJun 28, 2024 · The correction is therefore not exactly the same for every RAW image, but is exactly the same for the same lens, aperture and focal length. Of course, you have the (artistic) freedom to apply another amount of lens correction than LR suggest, depending on the scene or the look you're going for. WebA focal length of 16mm in with a FOV of 84 degrees. If you want to go the whole hog and capture a 180-degree view, you’d need a 10.5mm full-frame fisheye lens . That will, of course, give you plenty of distortion, but some actually like the effect.
