s-m-c takumar一般产于什么年份？我看好多照片上品相超好，出厂时间不长么？应该早停产了吧

http://www_taunusreiter_de/Cameras/Pentax_Takumar_e.html,这里可以找到你需要的信息.国外takumar的fans很多.大概的年份在60年代末70年代初.
Super-Multi-Coated Takumar Lenses (1971-1976)

After starting the multcoating of optical lenses in production the M42 Pentax Takumar lenses were changed in name once more.
These series are marked ´Super-Multi-Coated Takumar" in the front ring, or later abbreviated "SMC Takumar". To distinguish early from later series it is common among collectors beeing precise with the name, or if needed abbreviate the long diction "Super Multi Coating" as S.-M.-C. to distinguish it from later SMC-Takumars. As a rule of thumb, these lenses are also coupled for open-aperture-metering (For  Spotmatic-F, ES, ES-II) but there are some exceptions as well.

Takumar的调焦手感在所有的m42头里面是最好的,并且能够经历数十年不变,一个原因是采用石墨作为润滑剂.它的做工,和徕卡比也毫不逊色.

和徕卡的差距在于用料,徕卡定位于高档市场, 因此在选材用料上面规格比面向大众市场的都要好,它的定价也足够支撑它的用料.

其实翻新也没有事，有机会拆个镜头你就会发现，镜片是在镜身里面的一个小圆筒里，翻新的是外面的镜身

你不会用Google么？
