Olympus OM lenses

With the introduction of the Olympus OM system, a new range of lenses was designed by Olympus. All the lenses can mount on all the bodies, except for the following limitations:

• the Zuiko 500/8, Zuiko 600/6.5, Zuiko 1000/11, 24/3.5 Shift, 35/2.8 Shift and Auto Bellows can't be used on OM-101/OM-88;
• the Zuiko 500/8, Zuiko 600/6.5, Zuiko 1000/11 and Auto Bellows can't be used on OM-707/OM-77;
• 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.

The bayonet mount has a very large diameter, and all the lenses are very compact compared to other brands.
