OM System

OM-3

The OM System OM-3 slots between the OM-5 and OM-1 — a compact, weather-sealed Micro Four Thirds body with a 20MP Live MOS sensor, strong IBIS, and OM System's class-leading computational photography features. It brings improved autofocus over the OM-5 while keeping a lighter, more portable profile than the OM-1 flagship.
