Bernhard J. Oehler's optical company in Wetzlar, Germany, made the Oehler Infra rangefinder camera since 1950. It had a built-in extinction meter, used Agfa's Rapid film and produced 24 x 24 mm shots. It had a Pronto or a Vario shutter and a Felgner Punktar 1:2.8/32.3mm or 1:2.8/35mm lens. It was Oehler's only camera product.
