Zeiss Ikon Perfekt Camera (13 x 18 cm) with Double Protar 6.3/16

Zeiss Ikon, Dresden. "Perfekt" field camera, type 834, no. 87755, for 13 x 18 cm, Compur with double Protar lenses: Protarlinse VII f = 29 cm no. 686111 at the front and Protarlinse F = 285 mm no. 54840 at the back, shutter with aperture scale for single lens (aperture value halved when using the double lens), 2 replacement lens boards, 3 double cassettes and focusing screen back, shutter working, tripod holder modified. - Note: An original wooden field camera by Zeiss Ikon is extremely rare. All the combinations of the same focal length from the 4-element Protarlinse of the first version (up to no. 80000) together with the Protarlinse Series VII at the front result in the most powerful double Protar for an 80-degree field of view. More powerful large-format optics only appeared after 1970. Such combinations of "old and new" are rarely found because they have too often been separated again due to ignorance.

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)
