The tool calculates a lens multiplier, which tells you how telephoto or wide your shot will feel, using one formula: Multiplier = Lens Focal Length ÷ Recorded Horizontal Width. Pick your camera, sensor mode, and lens type (spherical or anamorphic), then enter a focal length.

A multiplier of exactly 1.0x is the orthographic lens, where the focal length equals the recorded horizontal width. Orthographic is a projection method where parallel lines remain parallel and objects maintain the same scale regardless of their distance from the camera, producing the most balanced, transparent perspective and the closest match to human spatial perception.

Below 1.0x is wide (immersive, distorted), and above 1.0x is telephoto (compressed, isolating). Click any famous-film card or preset chip to load that exact setup, or use Compare to see how the same field of view translates across two different cameras.
