Zuiko is the name of the camera lenses made by Olympus, from the first one, mounted in 1936 on the Semi Olympus, to the present day. All the Olympus cameras use the Zuiko lenses made by the company.

Zuikō is written 瑞光 in Japanese and can be translated as "auspicious optics" or "auspicious light". The name was adopted after a contest open to the company employees,[1] being a contraction of the first characters of "Mizuho Kōgaku Kenkyūjo" (瑞穂光学研究所, meaning Mizuho Optical Research Institute), name of a branch of Takachiho Seisakusho (the later Olympus) founded to develop the camera lens.

Where a lens is denominated with a letter before the Zuiko name (e.g. D.Zuiko or F.Zuiko) it represents the number of optical elements in the lens. The letter's placing in the alphabet corresponds to the number of elements present — so a D.Zuiko lens has 4 elements, and a F.Zuiko has 6.
