Carl Zeiss Jena Apo-Tessar 1:9 f=6cm ULF – process lens

Ultra large format or process lens. 600mm F/9 with a huge image circle, APO corrected for beautiful color reproductions, at least covers 8×10 and is rumored to have a 90cm image circle. This copy is in outstanding condition, when looking through the lens you don’t see any haze, fungus or issues at all. Its really crystal clear and above average clean. Produced in eary 50s probably. T coated. Aperture ring a bit stiff but still works as intended, beautiful round bokeh due its many rounded blades. Probably used in a fixed indoor setup or machine, thats why it’s still so nice. Some very very faint swirly cleaning marks on both front and rear element, but these will definately never show up or cause any issues at all. Some normal usermarks and paint wear on the barrel but overall in a perfect shape, ready for its next use. Measures 92x75mm. No flange, diameter of screw is around 86mm.
