The original Mikroma appeared in the late 1940’s, and in 1957 Meopta opted to produce an updated version. It has the same body design as the original Mikroma so it’s easy to miss the few improvements. One big difference is that this model has an improved range of shutter speeds — increased to 1/5-1/400. On the original, the shutter release and the film advance functions were built into one lever. On this model they are separated and the camera has a normal shutter release button. And to top it off, a wider variety of accessories were available, such as filters, close-up adapters, a copy stand, film cutting and viewing devices, an enlarger, and a developing tank.
The camera came with a 20mm (f3.5-16) focusing lens and was available in black, brown and green leatherette. It created 11x14mm images and was designed to use single-perforated 16mm film in special cassettes.
A single lever is used to advance the film and make the exposure, this is clumsy to use and was changed in later models. There are only two speeds marked on the shutter selection disc but intermediate speeds can be set. Other examples have different speeds indicated. Late models have two flash synchronizing sockets on the camera front. The price in 1953 was £28.0.0.
A Mikroma II appeared in the late 1950s, this had flash synchronizing as well as a separate shutter release and increased speed range. A stereo model 11 was produced. Versions with colored leather exist.
