Item Name : Carl Zeiss Jena 55mm f6.5 Lamegon
Serial no. : 7350905
Reference : Extremely Rare !!,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 : shutter sticky,very very faint front cleaning marks,no haze
Remark :
Cosmetic Condition  : EX+++
