Mamiya

Mamiya is a Japanese camera and optics company known for its line of medium-format film cameras and lenses. The brand produced several influential systems, including the modular RB67 and RZ67 SLR backs, the 645-series for 6x4.5 formats, and the Mamiya 6 and Mamiya 7 line in 6x6 and 6x7 formats. Lenses were marketed under the Sekor name, a designation associated with high optical quality.

Founded in Japan as an optics maker, Mamiya built a reputation for robust, professional hardware. The RB67 and RZ67 lines offered modular bodies with interchangeable backs and lenses, a feature that supported various film formats. The 645 system provided a more portable option for studio and location work, while the Mamiya 6 and Mamiya 7 offered rangefinder designs for different formats.

In the digital era, Mamiya expanded into digital imaging, producing digital backs and collaborating with other manufacturers to adapt its systems to electronic sensors. The company’s digital-imaging assets were later integrated into Phase One’s portfolio, and the Mamiya brand became largely associated with legacy products as Phase One continued to develop its own platform.

Today, Mamiya cameras are regarded as robust and high-quality by collectors and photographers, particularly the RB/RZ and 645 systems, as well as the Mamiya 7’s image quality and portability. The brand's lenses, especially those in the Sekor line, remain noted for optical performance and adaptors that extend their use to modern digital backs.
