The Leica MDa, produced from 1966 to 1976, is the M4-generation successor to the MD. It carries the M4 film transport, with the quick-load take-up spool and angled rewind crank, in a viewfinderless body with no rangefinder. Like the MD it was sold for photomicrography, copying, and scientific use, often paired with the Visoflex III or a reproduction stand. Roughly 14,400 units were produced (catalog 10103), making it by far the most common of the technical M bodies. On the used market the MDa is the most affordable way into the viewfinderless M family, and many are shot handheld today by scale focus, framing through a shoe-mounted finder.
