I couldn't find this Pentax lens in the Lens review database. It appears to be a Pentax-A 70-200 (not 210) f4. The seller says it's hasn't got smc written on it anywhere.
Yea thats just the same thing as the Takumar 70-200/4. Single coated and gaaarrrbage unless you are looking for a softie lens which this lens might actually be quite useful. You get a kinda diffused soft glowy look which can be used for romantic portraits and what not but the lens doesn't really sharpen up till f8-f11.
This is a telemacro design where as the SMC version is a close focusing macro. Macro mode at 70mm vs. Macro mode at 200mm for the non smc lens.
