Item Name : Carl Zeiss Jena 110mm f16 Lamegon on Sinar Board
Serial no. : 7372879
Reference : Extremely Rare !!,cover 6x8in without movement,Lamegon is one of the few lenses delivering some 250 l/mm and was made in very limited numbers, quasi-symmetrical 8e/4g (8 elements in 4 groups) design,with less than 5 micron distortion over the entire field. It has originally been designed based on a simplified Biogon design, initially for aerial imaging, later also for microreproduction, hence the very high resolution and flatness of field. One of the former lens designers told that especially the glued inner three elements demanded a very high manufacturing effort to produce and that the inner air gaps were adjusted per batch (!!) to compensate the effect of refraction differences in glass melt batches.
Glass Description : very faint front & rear cleaning marks, slight coating wear on edge of front & rear element,no haze

Item Name : Carl Zeiss 153mm f5.6 Pleogon A2 Aerial Lens
Serial no. : 116264
Reference : Huge & Extremely Heavy lens,over 43lb,optimized Biogon for 8x10" format ( image circle 320mm ). comes with an rotary shutter, used in aerial mapping cameras, but the motor is missing, so it has to be controlled manually. The resolution and contrast depends on the f-stop. At f/4 the resolution in center is 390 lppmm, high contrast,at the corner resolution is just 80 lppmm, low contrast at f/11  the resolution is over the complete image field 140 lppmm on very very high contrast.The "A"in the name will say, it is an apochromatic lens, corrected for blue, green, red and infrared.Since it is designed for photogrammetry purpose, it is tending to zero distorsion.

Item Name : Carl Zeiss 180mm f5.6 Topogon V Aerial Lens
Serial no. : 136068
Reference : That lens is one of the sharpest aerial lenses around still,uses it to take aerial shots and enlarges it with his ZEISS SEG enlarger. looked at a negative with a microscope showing Frankfurt airport from about 3000ft - you could virtually stare into passengers nostrils and I was blown away! some tests shots with Siemens stars in quite some distance and using the microscope again could see that the lens had an even better resolution that this high resolution aerial film could resolve. Just amazing. measurements showed a resolution of about 125...140 lpm. ,The Topogon 180mm f5.6 is really the proud of the Carl Zeiss Photogrammetry Division, as they told me
