The Mec 16 is a viewfinder camera for 10×14mm-sized shots on 16mm film in special cartridges. It was one of the cameras of the post-war subminiature camera boom. It was made from 1958 by Feinwerktechnik GmbH in Lahr, in the Schwarzwald in Germany, a subsidiary of INA-Werk in Herzogenaurach which made the Navax 35mm camera.

Opening the camera by sliding out a frame at one end exposes an optical viewfinder, and also opens the sliding lens-cover. On this cover, the lens is identified as a 20 mm f/2.8 Color-Ennit, by Enna.

A second model in 1960, the Mec 16 SB is similar, but improved by the addition of a built-in Gossen lightmeter. It was the first camera to offer through-the-lens metering.
