![]() Among the latter, 300, 350, 400, 600 and 1,000 mm refractors were available, as well as a 500 mm catadioptric. Focal length varied from fisheye to supertelephoto. The original Zuiko lens series introduced a large number of prime lenses and a few zooms. As typical of lenses of the time, they have manual focus and aperture, albeit with focus and exposure fully open and stopped down to the preset aperture by the camera body. The cameras were characterized by very small sizes for the time, and most of the lenses were designed to complement the camera sizes without compromising on optical quality. 90-250/? prototype of 85-250/5 - Unknown max aperture, maybe F4 or F3.The Olympus OM series of 35 mm SLR cameras and lenses (the latter branded Olympus Zuiko) was introduced in 1972 and discontinued only in 2002.85/1.4, prototype, with GRIN (GRadient INdex of Refraction) elements.50/2 pancake, prototype of 40/2 pancake.18/3.5, prototype of 18/3.5, L.zuiko with 12 elements 10 group, fixed 72mm thread.Here is a list of the manual Zuiko lenses that were never marketed: 70-210/3,5-4,5 PF rare, modified AF without electrical contacts, but with rectangular part for the contacts.However, if, when fitting these lenses, they are not twisted all the way on, the front part of the lens can be used as a focusing ring: this still maintains light-tightness. All these lenses lack a manual focusing ring, so cannot be used on manual OM bodies, or 4/3rds cameras (not even with OM adaptors). The powerfocus lenses are specific to the OM-101 / OM-88. The autofocus lenses were intended for the OM-707 / OM-77 but they can be used on the OM-101 / OM-88 too. the autofocus lenses for the OM-707 / OM-77 and OM-101 / OM-88 bodies, those lenses do not have a manual focusing ring and are useless on the other bodies. ![]() At the height of its success, the OM system had the largest range of f/2 lenses of any camera manufacturer or system ever made before, including f/2 macros and telephoto primes up to 250mm.Īll the lenses can mount on all the bodies, except for the following limitations: Olympus was able to offer this range of very fast, compact lenses due the width of the lens mount. There was a 'prosumer' model released with a f/1.4 maximum, and even further a professional model with a maximum aperture of f/1.2. Referral to the below list of released system lenses will show the 'consumer' model of the OM 50mm for example has a maximum aperture of f/1.8. The differentiation of the lenses was done simply by their maximum aperture. Where many companies released consumer-class kit lenses made out of inferior products or designs, all Olympus OM lenses were made to the same high standard. The bayonet mount has a very large diameter, and all the lenses are very compact compared to other brands.Ĭompared to many other manufacturers, Olympus took a slightly different approach to lens grading. With the introduction of the Olympus OM system, a new range of lenses was designed by Olympus.
