Mamiya C33 Professional Twin-Lens Reflex (TLR) Medium Format Film Camera with Mamiya-Sekor 135mm f/4.5 Dual Lens Pair - Good Condition | Heavy-Duty Studio Camera Featuring Automatic Shutter Cocking, Bellows Parallax Indicator, and Rare Premium Telephoto Portrait Optics

Introductory Paragraph The Mamiya C33 Professional is a legendary, high-performance interchangeable twin-lens reflex (TLR) medium format film camera built by Mamiya in Japan. Standing out as an industry pioneer among TLR systems, the C33 features an advanced mechanical linkage that automatically cocks the shutter when the film advance crank is turned, completely eliminating the risk of accidental double exposures. Outfitted with the premium Mamiya-Sekor 135mm f/4.5 dual telephoto lens system (comprising a dedicated viewing lens and a matching taking lens with its integrated mechanical Seikosha shutter), this scannable Mamiya setup provides a flattering focal compression ideal for intimate studio portraits and fine landscape photography. Operating entirely without electronics on 120 roll film, it remains an exceptionally satisfying, rugged workhorse for vintage analog collectors and fine-art portrait artists.

Key Features

• Advanced interchangeable twin-lens reflex system layout, providing access to a legendary library of Sekor optics via a robust dual-wire lock bar latch mechanism.

• Automated one-step crank film advance and shutter-cocking mechanics, streamlining your workflow while preventing double exposures during fast-paced shoots.

• Integrated bellows extension focus rack configuration, allowing dramatic, ultra-close-up macro capabilities that standard fixed-lens TLR cameras cannot achieve.

• Premium Mamiya-Sekor 135mm f/4.5 telephoto portrait optical pairing, providing a flattering perspective equivalent to a 70mm lens on a 35mm full-frame format.

• Dynamic viewfinder parallax compensation indicator needle, shifting behind the focusing screen automatically to show true framing boundaries as the bellows expand.

• Highly reliable Seikosha mechanical leaf shutter assembly, integrated directly into the taking lens to allow flawless flash synchronization at all speeds up to 1/500s.

• Robust all-metal industrial frame structural engineering, cloaked in a premium textured leatherette skin designed to withstand generations of professional creative use.

Condition Report Good condition. Body: Shows standard light signs of professional past handling, including typical minor surface scuffs on the black crinkle-finish metal panels and light superficial edge wear on the lower chassis corners. The leatherette covering is entirely intact and secure, and the film door seals shut tightly. Sensor/Optics: The waist-level finder pops open decisively, and the ground-glass focusing screen provides a clear view. The matched 135mm viewing lens (S/N: 683933) and taking lens (S/N: 683993) elements are bright and clear, completely free from internal fungus, heavy haze, optical separation, or deep structural glass scratches. Mechanics/Electronics: Fully operational. The side focusing knobs and bellows rack extend uniformly without slipping, the film advance crank turns smoothly while simultaneously cocking the shutter, the Seikosha mechanical leaf shutter triggers snappily and accurately across all speeds, and the manual aperture selection pins click cleanly.

Specialist Note "The Mamiya C33 is an absolute masterpiece of mechanical design. Unlike fixed-lens TLR cameras from the era that limited you to standard focal lengths, Mamiya built a real system camera with a heavy-duty bellows track. The 135mm f/4.5 lens included here is widely considered a secret weapon for portrait photographers—it hits the sweet spot between standard 80mm and long 180mm lenses, offering gorgeous background separation and beautifully compressed facial features. Because Mamiya used separate serial numbers for the viewing and taking optics on this generation, finding a cleanly matched pair like this is a real treat. It is a completely transparent, satisfying, and incredibly rewarding camera to shoot out in the field."
