Overview / 概要
Why Olympus OM-1 matters.
The OM-1 changed expectations for SLR size and remains a masterclass in packing controls into a calm object.
Design & context
Its compact prism, large finder, and lens-mounted shutter-speed ring make the camera feel unusually balanced.
Buying today
Meter conversions and prism condition matter; the camera is lovely to use, but not every example is equally serviceable.
