Thanks to the hard systematic work, our database contains photos, model history, camera compatibility information, specifications and descriptions for 4444 autofocus and popular manual focus interchangeable lenses designed for SLR, rangefinder and mirrorless cameras: from APS-C to medium format 6x7cm, from fisheye to super telephoto lenses, from macro and bellows to soft focus and mirror/reflex lenses, from Asahi/Pentax, Canon and Nikon to LEICA and ZEISS.
The data come from the extensive collection of documents from manufacturers and dealers: 2400 booklets, catalogs, ads, instruction manuals and datasheets. This makes our database the world's largest credible.
