On the History of Schneider-Isco Lenses

Cinema projection lenses in international competition. All lenses performed well to cleanly under point light. 1) Isco Cinelux-Ultra MC 2/100 no. 51674. – 2–3) Schneider Cine-Xenon 2/100 mm MC and 2/90 mm MC. – 4) Isco Ultra MC 2/100 mm no. 400036. – 5) Schneider Super-Cinelux 2/80 mm 35mm film no. 14699996. – And: 6) Isco Ultra-Star HD 85 mm MC no. 885431. On this lens, only the screw-on gold-colored mount shows significant wear from the anamorphic attachment. This lens represents one of the best projection technologies ever available; the image format is considerably larger than that of a 35mm lens, offering outstanding point sharpness right to the outer edge of the entire image circle. – Note: The web page deltalenses.com/the-kiptar-story contains an extremely detailed history of the two companies, published April 23, 2025. A must-read!

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)
