关于玛米亚
玛米亚（マミヤ；Mamiya，或又译为间宫）是一日本照相机品牌，由间宫数位影像（マミヤ・デジタル・イメージング；Mamiya Digital Imaging）所拥有。间宫数位影像是一家设址于日本东京都台东区上野的中篇幅照相机专业厂商，创立于2006年（平成18年），但其品牌渊源最早可回溯至1940年（昭和15年）时，发明家、相机设计师间宫精一在菅原恒二郎的赞助下所创立的“间宫光机制作所”（マミヤ光機製作所）。在2006年之前，Mamiya这品牌原本是由间宫-奥林匹克（マミヤ・オーピー株式会社；MAMIYA-OP Co., Ltd.，是由间宫光机与奥林匹克钓具所合并而成）所拥有，但由于不堪长期的亏损，该公司在2006年时将旗下所属的光学仪器部门出售给凯思科学系统（株式会社コスモ・サイエンティフィック・システム；Cosmos Scientific Systems, Inc.）特别针对收购案而新成立的子公司“凯思数位影像”（コスモデジタルイメージング）[1]，并在之后改名为“间宫数位影像”继续营运。

关于RB67
The first camera released was the RB67 Professional in 1970. The system comprise of a camera body, viewfinder, back adapter, film back, and lens. The camera body itself is quite simple and fully mechanical. It does not require any battery power. The shutter button is located on the front bottom right of the camera. It can be locked with a twist of the collar. The shutter is cocked manually by pressing down the large dominate leaver on the right hand side of the body. The mirror within the camera and shutter in the lens are cocked at the same time. There are two focusing knobs on each side of the camera body similar to the Mamiya C series TLR’s. The focusing screens are also interchangeable. The most common back adapter included in the system is the rotating back. The naming of the camera RB67 stood for Rotating Back 6 × 7.
The RB67 was originally designed to supplement the Mamiya C series 6 × 6 TLR system and the multi-format Mamiya Press rangefinder camera system (6 × 4.5, 6 × 7, 6 × 9, others) but has surpassed them in popularity. Back adapters for using Mamiya Press roll film and instant film backs are also available. Due to its heavy weight (almost 2kg for the body alone) the RB67 is often said to be unsuitable for use hand-held use. This isn’t necessarily true – with a decent neck strap the RB67 can easily be used on the move. The flexibility of the RB67 system made it one of the most popular studio cameras in the 1970’s.
