How do Takumars work on K-1?

M 42 Takumar lenses

M 42 Takumar lenses were introduced with the famous Asahi Pentax in 1957. They were high-class lenses at the time. But how will they work on a modern full frame DSLR?

I have tested some Takumar, Auto-Takumar, Super-Takumar and S-M-C/SMC-Takumar lenses for sharpness and colour rendition on K-1. Other optical qualities are not tested. 

Comments are given for centre sharpness and corner sharpness respectively, from wide open to 8, where most lenses are at their peak. Photos showing colour rendition will follow.
Pentax D FA 100/2,8 Makro WS is used as a reference. 

The conclusion for the lenses I tested is: Yes, they work very well with K-1! There are some very sharp lenses among these veterans. Some even outperform the reference! There are also a few that are not worth using. 
As for colour rendition, all lenses give clear red, blue, green and yellow.

A scale from 1-10 is used for sharpness. 
Very soft is used when points are <6
Soft is 6-6,5
Fair is 7
Good is 7,5-8
Very good is 8,5-9
Excellent is 9,5-10.

The very best lenses are marked with a Vill, the very good ones with aSmiler stort, and the good ones with Kul.

Interesting website, nice to read about the pentax camera history and others.

You are quite right. The vignetting disappears at 22, so it is usable from there on, but the maximum never exceeds 45. Thank you!
I will correct it. Bosse

Hi Eric,
I don't understand your phrase: "Recommended as a 22-60 wide angel on K-1, and as 16-45 on K-3 II." The focal length range remains the same.

Thanks for the comment.But the page actually states that the FT-1 was following the FS-1, worlds first camera with a built-in motor.(Under the last photo.)
