Ikophon Sound Film Camera, c. 1938

Zeiss Ikon, Dresden. A high-quality film camera designed for single-perforated 16mm film. Three cassettes for daylight-loading spools of up to 60 meters. Battery-operated synchronous motor. The intermittent movement mechanism was adopted from the Movikon 16. – Four lenses on a rotating turret: Carl Zeiss Jena Tessar 2.7/15 mm, Sonnar 4/25 mm, 2.8/50 mm, and 4/75 mm. A sensational Newton-type viewfinder with a coupled rangefinder and parallax compensation for all focal lengths, a masked display indicating the various field-of-view sizes. (3+/3+) – In addition: A wooden tripod with a large aluminum head (the wedge plate for mounting to the camera base is missing but can be easily fabricated), the very rare original Klangfilm microphone designed specifically for the "Ikophon", a vintage pair of headphones, two incomplete optical sound amplifiers, the battery pack, and several original cables, all housed within two "Ikophon" transport cases. (4+/4) – Electrical functionality remains untested. – Special feature: In addition to capturing high-quality images, this camera was capable of simultaneously recording synchronous sound – encoded as variations in optical density – directly alongside the images on the film strip (utilizing the Klangfilm optical sound system). After processing through the amplifier units, the microphone signals were routed to a photocell located within the camera (resulting in a standard image-to-sound separation of 28 frames). The first unit was unveiled at the 1938 Leipzig Autumn Trade Fair under the slogan: "Now, in addition to the image – the sound." The declared target audience consisted of the discerning amateur filmmaker or the professional cameramen working for the "Paul Nipkow" television station – operated by the Deutsche Reichspost (German Imperial Post) – which had been broadcasting since 1936. The narrow optical sound track proved difficult to duplicate; consequently, the original camera negatives remained unique, one-of-a-kind artifacts, which ultimately limited their wider distribution. Due in no small part to its high price point, only a very limited number of these cameras were ever manufactured. Shortly after the outbreak of the war in 1939, production was discontinued in 1940. – The "Ikophon" is considered the rarest 16mm camera in the world.

布雷克拍品等级是为了方便竞买人判断拍卖品的成色而设置的。布雷克等级用1到6级来标注外观和功能的成色，(从非常好到非常差)。 在目录图册里用括号里的2个数字来表示，前一个数字表示外观成色的级别，后一个数字表示功能成色的级别。如(3/2)表示外观成色是3(满意的)，功能成色2(好)。 成色 定义参照下列标准： 1 - 非常好 (未使用过，没有使用痕迹) 2 - 好 (新，极少的使用痕迹) 3 - 满意的 (普通的使用痕迹) 4 - 及格的 (明显的使用痕迹，某个非主要部件是后配的) 5 - 有缺陷的 (极明显的使用痕迹, 某个主要部件是后配的，功能上有缺陷，需要修理) 6 - 非常差 (严重破损, 缺少重要部件)
