Mamiya-Sekor Super-Deluxe[]

The Mamiya-Sekor Super-Deluxe is series of 35mm fixed-lens rangefinder cameras, manufactured by Mamiya and produced in the early-mid 1960s.

Three variations of the basic design were produced:

  • 48mm, f2.0 Mamiya-Kominar lens
  • 48mm, f1.7 Mamiya-Sekor lens
  • 48mm, f1.5 Mamiya-Sekor lens

All models are equipped with a Copal-SVE leaf shutter, with speeds of 1/500 to 1 second plus B. X and M flash sync is provided by a PC post connector. A cold accessory shoe is provided, but does not support hot-shoe flash operation. A self-timer is provided.

Focusing is facilitated by the built-in bright parallax-corrected rangefinder.

Metering and exposure[]

An internal CdS photocell, mounted above and to the side of the lens, is the measuring element. Match-needle manual exposure control is provided by a top-mounted meter with the needle visible at the top of the viewfinder.

The metering circuit is powered by a PX625 mercury cell, which is not available in the United States and some other countries. Many substitutes and work-arounds are available in lieu of the original PX625. The metering circuit is turned on and off by a round knob switch on the rear of the camera body. Since the photocell is uncovered, it is possible to run down the battery if this switch is inadvertently left in the ON position.

The Mamiya Super Deluxe only supports film speeds up to and including ASA 800.


While not considered rare by any means, the Mamiya SD is not nearly as common as the well-known fixed-lens rangefinders from Canon and Olympus.

The 48mm, f1.7 version is the most common of the three and appears occasionally on eBay and other auction and used camera sites. Used instruction manuals are commonly available. Service manuals are rare.
