The Rolleiflex 3.5 Automat MX may be the most classic of all Rollei TLR cameras. Built between 1951-54 during the height of Rollei’s dominance of the post-war professional camera market, over 109,000 were produced. Fitted with sharp Schneider Xenar or Zeiss Tessar lenses, Rollei 3.5 MX cameras saw hard use in the hands of many photographers, but clever design and durable construction make them among the most reliable classic cameras to use today.
The Rolleiflex 3.5 MX, as its name suggests, is the first Rolleiflex model to house a Synchro-Compur shutter capable of M or X flash synchronization. While this flash compatibility is unlikely to be a critical factor for modern photographers, the 3.5 MX has a number of other features that make it a better choice for photography today than earlier Rollei models. These include provision for the Rolleigrid fresnel brightening screen and new baffles in the film chamber that substantially reduce reflected light. It is also the first Rollei to feature the groove in the tripod base for use with the Rolleifix tripod adapter.
Like all Rollei models, it is known by a variety of names: Rolleiflex 3.5 Automat MX, Rolleiflex 3.5 MX Sync, and Rolleiflex 3.5A, all referring to this camera. For its part, Rollei marketed the 3.5 Automat MX simply as the “Automatic Rolleiflex” and gave it the internal designation Rolleiflex K.4A.
Rolleiflex Automat MX TLR Camera With Sports Finder
The Rolleiflex models from the 3.5A onward have an ingenious prism mirror setup built into the sports finder. This allows the user to quickly check focus while tracking a subject through the sports finder frame. This feature was discontinued for the Rolleiflex T but continued as standard equipment of the 3.5F and 2.8F model lines.
