Model Details

Manual focus M-mount 35mm camera released by Leica in 1966. The MDa is a follow-up to the original MD, now built upon the M4 instead of the M2. It is a specialty camera intended for scientific applications such as photomicroscopy. The body lacks the viewfinder, rangefinder, field frame selector, and self-timer. This version of the camera has a slotted accessory port on the base plate that accepts 4mm wide special plastic marker strips. This allowed the recording of data onto the negative. The area of the negative that records the subjects was made slightly smaller to accommodate the data strips. Metal body available in silver (10913).

  • Shutter: Horizontal cloth focal plane, 1s - 1/1000s + B
  • Size: 138 x 77 x 36 mm
  • Weight: 595g

Leica M

Leica’s M mount was introduced in 1953 alongside its first camera, the M3. Despite the rise of the SLR, Leica cameras have continued to succeed as their unique combination of build quality, speed, and discretion sets them apart from competition. The M bayonet mount, and the cameras introduced alongside it, offered (& continue to offer) a number of advantages over SLRs and other rangefinder cameras.

One big advantage is automatic framelines, which react to the lens on the camera to show accurate framelines in the viewfinder. This is even possible with older Leica Thread Mount (LTM) lenses if the correct adapter is used.

Other manufacturers, such as Cosina Voigtländer, Carl Zeiss, Konica, and Minolta, have also produced rangefinder cameras using Leica M mount.
