Two versions of the shutter are known. On the early version, the release lever is attached to the front of the casing by a screw. The front plate is inscribed LICHT at the top and SEIKOSHA at the bottom, with an SKS logo on the right. The T, B, 100, 50, 25 speed settings are written in that order on the shutter plate itself, and they are selected by an index placed above. On the late version, sometimes called New Licht, the speeds are set by turning the rim, and the speed settings are engraved on the rim itself in the 25, 50, 100, B, T order. The release lever is now attached behind the turning rim, and the front plate has been slightly redesigned with no SKS logo.
Some examples are equipped with a regular self-timer activated by a lever, whereas others have a thread and needle release.
This list is incomplete, the fact that a camera is in the list does not mean that all its versions have a Licht shutter.
