I can't tell the difference in sharpness between the Vivitar/Tokina 135 and the Takumar 135/3.5 at f/4
The Vivitar is a bit soft at f/2.8, but so are most 135's.
Bokeh is better than the Takumar I think. But that Takumar is known for pretty hard-edged bokeh.
You may be able to find a difference if you run a real test, unlike my general impressions from use.
It also depends on what sort of sensor you have. I have a 12mp APS-C. Some of the newer 4/3 sensors for instance tend to show more differences between lenses. |
the takumar 135/3.5 is a four element nothing special lens so I wouldnt be surprised at your findings. the takumar to get is the six element smc takumar 135/2.5 (type 2, not the 5 element type 1). It is superb.

That Takumar 135/3.5 is sharp to the limit of my sensor wide open, so in my case, and I suspect for most people with typical DSLR's, any advantage of a better lens would be academic.

Yes, Hifisapi. Go for it, without hesitate.
I tried, as almost anyone did here, a lot of 135 mm lenses. And the SMC 2,5 "2 v." is one of the best. |

Yes, agree. But you can have a better cam in the future. And the lenses are so nice.  |

yes, that tak is 4 element, however it has excellent sharpness and color depth. so far it's the best 135 i got, and i am going to hang on to it until i will get something better, particularly i'm on the look out for tair 11a. but thanks for your input, if i come across 135/2.5 sms tak - i will buy it 
how can i differentiate between type 1 and type 2? Are there any visible differences? |

The only difference I know is the little number engraved on the back of the a/m switch.
The earlier version (5-4) has a number ending with 02, while in the latter (6-6) it ends with 12.
The latter is also slightly heavier
