根据wiki 的介绍:Version 1 (1974-1978, sn 224xxxxx - 227xxxxx) - This was the initial production version of the lens. It was soon discovered that there were reliability issues which Vivitar attempted to address through a series of minor changes. These changes were undocumented even in Vivitar service publications, with one exception - an \"improved helicoid assembly\" was introduced starting with sn 22528001 according to the service manual. However, all changes were designed to be backwardly compatible with the version 1 design. All version 1 lenses should be more or less interchangeable from a service perspective. Version 2 (1978-1981, sn 228xxxx - 221xxxxx) - In late 1978 Vivitar attempted to solve the reliability problems by introducing a major internal redesign of the lens known as the Z71 modification. Pre 1978 and post 1978 models are no longer completely interchangeable. The Version 2 redesign also introduced several additional mounts. Because of the redesign, Vivitar\'s internal stock numbers for lens changed (see stock number listings below). 第一版的镜头是有小问题的,所以我买的是Version 2, 镜身号须介于:228xxxx - 221xxxxx。不是此版本,并且镜身号不是介于此间的不能买。虽然目前价格有小涨,但超过90美元就算贵了。因为此镜实际操作非常困难,故使用价值不高。

收老镜头有时要靠运气,这只镜头版本很多,差距非常大。 我的这只很好,特别是色彩迷人。你好,这张照片是直出,还是有后期
