Zuiko
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. Olympus began to phase out these letter designations when introducing new products in the early 1980s (e.g. the XA-3 and XA-4).

6.5×9cm lens
- 105/4.5, four elements, three groups, first prototype lens made by Takachiho, intended for 6.5×9cm plate cameras[3]
High-aperture lenses
Three high-aperture lenses were developed from 1936–7, using Japanese optical glass, after a request from the Japanese government:[4]
- Zuiko f/2.7, five elements in three groups
- Falcon f/2, six elements in four groups
- Olympar f/1.5, six elements in five groups
It seems that the projects were first designed with a focal length of 50mm, then that a 65mm version of the Zuiko f/2.7 and Falcon f/2 was planned for the Olympus Standard.[5] It is unclear if any of these lenses were actually made.[6]
The Olympar f/1.5 design later evolved as the Zuiko 50/1.5, which was produced in small quantities and sold to Shimazu Seisakusho for X-ray cameras made around 1940.[7] It is said that some of these lenses appeared on the market after the war, perhaps in Leica screw mount and perhaps sold by Shimazu as surplus.[8]
Aerial lenses
- 200/4.5, four elements, three groups, marked ZUIKO 1:4.5 f=200mm Takatiho Noxxxx, for the Type 100 Small Aerial Camera (SK-100, 100式小航空写真機)[9]
- 250/4.5, four elements, three groups, for an Automatic Aerial Camera (自動航空写真機)[10]
- 400/5.6, four elements, four groups, for the Type 100 Small Aerial Camera (SK-100, 100式小航空写真機)[10]
Enlarging lenses
- 50/4.5 enlarging lens, sold ¥60 in 1941[11]
- 75/4.5 enlarging lens, four elements, three groups, marked Olympus Zuiko C. 1:4,5 f=7,5cm xxxxxx[12]
- 75/3.5 enlarging lens, four elements, three groups[10]
