The Lidex is a leaf shutter made by Molta (predecessor of Minolta). It is everset, has two shutter blades and was patterned after the Vario.[1] It seems to exist only in #0 size. It was succeeded by the Crown shutters made by the same company.

Versions Edit

The Lidex (1–200), surely called "Lidex A",[2] gives T, B, 1, 2, 5, 10, 25, 50, 100, 200 speeds. This version was Its shutter plate is all black, with the Lidex name at the bottom and an MTS logo on the right. The early examples have the words Patents(J.N.)–Pending at the top, replaced at some time by Patents–Nippon.[3] The version mounted on the original Minolta has a shutter lock added under the release lever.[4]

The Lidex (5–200), surely called "Lidex B",[2] gives T, B, 5, 10, 25, 50, 100, 200 speeds. Its shutter plate is the same, and is known with Patents(J.N.)–Pending or Patents–Nippon at the top.[5]

The Lidex C gives T, B, 25, 50, 100, 150 speeds, and has the name Lidex >C< instead of Lidex at the bottom. It is only known with the Patents–Nippon marking.[6]
