Voigtlander Ultramatic Series
All Ultramatics are SLR cameras, with a Synchro Compur shutter 1/500.
The earlier model has a selenium cell later models have a CdS cell.
Bessamatic and Ultramatic have the same bayonet mount,
but only lenses with a yellow dot on the bayonet mount
allow the full automatic functionality of the Ultramatics.
