Mamiya Digital Imaging Co., Ltd. (マミヤ・デジタル・イメージングー株式会社, Mamiya Dejitaru Imejingu Kabushiki-gaisha) is a Japanese company that today manufactures high-end cameras and other related photographic and optical equipment. With headquarters in Tokyo, it has two manufacturing plants and a workforce of over 200 people. The company was founded in May 1940 by camera designer Seiichi Mamiya (間宮精一) and financial backer Tsunejiro Sugawara.
Mamiya originally achieved fame for its professional medium-format film cameras such as the Mamiya Six and the Mamiya Press series. It later went on to develop the industry workhorse RB67 series, the RZ67 and the twin-lens reflex Mamiya C-series, used by advanced amateur and professional photographers.
Many Mamiya models over the past six decades have become collectors' items. The earliest Mamiya Six medium-format folding camera, the 35 mm Mamiya-Sekor 1000DTL, the lightweight 35 mm Mamiya NC1000, the 6×6 cm medium-format C series of interchangeable-lens twin-lens reflex (TLR) cameras, and the press cameras of the Super/Universal series are highly valued. Mamiya also manufactured the last models in the Omega line of medium format cameras.
The Mamiya (間宮) was a food supply ship of the Imperial Japanese Navy which was in service from the 1920s to the Second World War.
The Mamiya was originally meant to be an oil transporter but was instead outfitted to be a food supply ship. The Navy sent her to the Kawasaki Shipbuilding Yard where she was fitted with facilities for carrying enough food for 18,000 men over three weeks, and kitchens to produce large quantities of food including yōkan, manjū, tofu, and konyaku. A number of chefs and pastry chefs were employed aboard and she became part of the Combined Fleet.
Already old by the outbreak of war, she continued to be part of the navy's operations in the Pacific. On 12 October 1943, she was damaged by the US Navy submarine USS Cero near Chichi-jima, and on 6 May 1944, was again damaged by USS Spearfish in the East China Sea. In both cases she was repaired and returned to service. The food supply ship was torpedoed and damaged in the South China Sea (17°48′N 114°09′E / 17.800°N 114.150°E / 17.800; 114.150) by USS Sealion ( United States Navy). She was torpedoed again and sunk (17°48′N 114°09′E / 17.800°N 114.150°E / 17.800; 114.150) on the 21st by USS Sealion.
