Takumar (Bayonet) 1:2.5 135mm, I really like the way this handles, and in conjunction with green button and judicious over or under adjustments via aperture ring, I love the results.

What do people think of these examples.

A small amount of level adjustment and cropping that is all made to them.

I never thought the 135 f/2.5 Takumar was that good. Puts a lot of
later lenses to shame. Nice Boat.

Thanks Shim, I hesitated after reading uncomplimentary comments, glad I ignored and went with my head.

Nice soft feel to the images, Pleasing to the eye in a sort of filmic way. Where in Switzerland are you?

Those were taken in the town of Zug, Central Switzerland.

Looks good to me. What apertures were those shots at?

It will be most interesting to see what it's like at f2.5. Wide open is when you tend to notice most difference between a good lens and a not-so-good lens. The large maximum aperture of these telephoto primes provides the main advantage (in my opinion) over budget zoom lenses, so you want to be able to use it. That's what I mostly use my smc 135mm f2.5 for anyway.

You will be better off using the SMC version, but as we can see the Takumar(Bayonet) version is not al all bad.
Best regards, John

Between F22 and F11. I have yet to try at 2.5.

Iceblinker those two shots of yours are superb.

Both taken at F2.5 i.e. wide open.

Looks sharp enough at f2.5, although there's a touch of purple fringing on the second shot.

You've got a nice usable lens there.

The first one's not too bad, but the second looks poor, but
that's what you would expect from a budget lens. Still worth
having because of the brighter viewfinder image and better
and quicker MF plus decent results stopped down.

I remember seeing a load of these lenses stacked like cans of
beans in a local wholesalers (Makro) in the late 70's. The stack
must have measure about 1M x 1M x 1M all in plain white boxes.
They were selling them for 30 GBP each which was very cheap.
They must have bought all Pentax's stock.

These pictures aren't too bad, though they could do with a bit of tweaking. Contrast isn't as high as it might be, and I think that is the main problem with this lens. The lack of coating is responsible.

Not really a landscape lens, but fine for closer subjects in good light (but not into the light).

SPB's second f2.5 shot is sharp where the cobwebs are. Don't forget my images above are smaller - the downsizing effectively sharpens them more. Processed RAW as well.

I suspect with careful focusing and processing, you could get nearly as good images from the Takumar wide open, and just as good at smaller apertures.

The SMC lens suffers from CA as well - green (not cyan) - which can't always be corrected with Silkypix (but perhaps can with other programs).
