Super takumar 135 f.2.5

There are three versions of Supertakumar 135 f2.5. Is there a lot of difference between the three? What is the best? How can you recognize the version?

Apart from the Takumar Bayonet with K-mount. (ignore those). There are The Super-Takumar 135mm F2.5 with five elements and two versions of the Super-Multi-Coated Takumar 135mm F2.5. Version one has five elements and is optically identical to the super-takumar but with s-m-c coatings and version two has six elements and is optically identical to the SMC Pentax 135mm F2.5 in K-mount. Version two is most sought after. Easy to discern from version one by looking at the distance scale. The first meter marking is 35 on version two. On version one it is 30 like on the super-takumar.

The Super-Takumar front element coatings look yellowish-gold on the front element, purple on the rear. Super-Multi-Coated has less reflections and looks more like any Pentax K or M lens. The extra element in the six-element makes it weigh more, but they did not really care that one lens weighed a few grams than its official specified weight, so don't be too picky about weight. The camera side of the A/M switch has a part number stamp. It should be 43801 for a Super-Takumar, 43802 for the version 1 five-element Super-Multi-Coated Takumar, and 43812 for the six-element version.

The Super-Takumar often sells for cheap and is worth picking up for say $40. You probably won't make money selling it later but it's not bad.

Actually the Takumar Bayonets are highly under-rated lenses that can represent real bang for buck.

I have one. Wide open it is terrible but OK from F4. The six element s-m-c takumar is much better.

Interesting - my Tak Bayonet 2.5 is easily sharper than my old 5 element super tak and SMC tak 2.5s wide open. Suggests a bigger gap between them and the 6 element than I was expecting. Here is a test I did with them wide open including other 135s. So 100% crops of the image.
Isn't the old 1958 Takumar 135 3.5 (46mm filter) performing well?

It is night time here so how about this for a comparison? Interesting how the Tak Bayonet has blue fringing as against red fringing in the others. Might be just a slight focus difference.

I don't think this is really relevant to OP's questions as the Takumar Bayonet is a different lens.

I'll show you what I mean These are crops:
F2.5


F4


See the glow all over the F2.5

I like the comparison which includes the 46mm Takumar 135/3.5. The one I have is a preset, with a really small base. I would not have predicted it was that sharp.

Yes indeed.
I might run a bright light daytime comparison and create a thread elsewhere
It is interesting how polarised the views are in the lens reviews - both your and my opinions would fit in comfortably.
