A number of the shots on the Pentax K1000 film I developed a few days ago, were taken with a range of M42 telephoto lenses. The lenses were fitted using a K to M42 adapter, and all exposures were made of the same view, with the camera on a tripod. The lenses were all full open.
First, a Harmony brand 300mm f4.5 preset - a big old lens, with fungus on the rear element.
Then, a Takumar 200mm f3.5 preset lens.
A Sigma Multi Telemax 135mm f2.8, a YS mount lens with a curious macro system, which involves moving the front elements.
Finally, a Super Takumar 135mm f3.5 lens.
Unsurprisingly, the sharpest lenses were the Takumars.

So no surprises here and indeed in the line of expectation. The takumar 200 shines both in contrast and sharpness. A bit unfair for the sigma as it is 2.8, at that f stop very little (tele)lenses ar at their best.( a decent 3.5 performs better wideopen) Still a comprehensive test, great thing you went through the trouble of using film. I've got a lot of 200 mm lenses myselve and might consider putting them through the test as soon as i am finished with my old glas on micro four thirds project.
