Calculates the equivalent lens focal length to produce the same field of view between two cameras with different aperture/sensor sizes. It will do a "Match Lens" computation and produce the closest equivalent angle of view lens, in millimeters, for both vertical and horizontal frames, between the original camera's focal length and the current camera's focal length.

While MatchLens is slanted toward the movie industry, most still camera formats/sensor sizes are also listed.

MatchLens 1.0 sells for $9.99 in the App Store.
