A very rare low-production lens, it falls in between 200 and 300 mm, so it was quickly replaced by those lenses. This is a very large and heavy lens, with a pre-set diaphragm. All lenses over 200mm, until the rubber grip series of late 1972, have the focal length inscribed in centimetres. Thus this lens is 25cm, the 300/4,5 is 30cm, the 1.000/6,3 mirror is 100cm, and so on.确实，这个镜头的生产量不大。1959年的老镜头，4组6片，滤镜77mm，尺寸为直径82mmx长度230mm，重量达到1.4kg。最近拍摄距离3米，最小光圈f22. 作者: cdhunter 时间: 2017-6-14 19:34
