Lensfun database
A portion of the camera and lens specifications (391 of 424 bodies and 967 of 1037 lenses) is derived from the Lensfun project (source), licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported license (CC BY-SA 3.0).
Changes were made: the Lensfun XML was transformed to JSON/SQL, focal length and aperture were parsed from model names, mount names were normalized, and sensor format was inferred from crop factor. These derived rows are redistributed under the same CC BY-SA 3.0 license.
