These comprised improvements like a faster shutter with 1/1000-second top speed, a frame counter, wind-on lever, and an Instant return mirror on model B in 1958.
In addition, a rare Miranda TII with 1/1000-second top shutter speed does exist.
[1][2] The Miranda cameras were equipped with a double lensmount consisting of a wide 44mm internal thread and an external bayonet—the Pentax/Praktica screw mount is 42mm.
The flange to film plane distance was deliberately made as short as possible to accommodate as many different makes of camera lenses as possible using separately-sold lens adapters.
However, by the end of the 1950s, Soligor became the main supplier, and soon the lenses were labelled Auto Miranda.
