The Olympus XA was a series of 35 mm cameras manufactured and marketed by Olympus of Japan from 1979 to 1985. The original XA was a rangefinder camera with a fast 35 mm f/2.8 lens, and aperture priority metering. It was one of the smallest rangefinder cameras ever made, together with the Contax T. Later models—XA2, XA3 and XA4—featured scale focusing instead of rangefinders.
