Went out with the Super Tak 1.8/55 today.
To catch some Autumn color "up close and personal".

Hi,
Where could I find an exhaustive complete list of Takumar lenses (especially the 50mm's), necessarily including the optical formula for each one.
I search for something in Bojidar Dimitrov style (too bad he doesn't include the M42 lenses in his lists).

I'm searching that as I am working on a research study (for a Ph.D aggregate) upon the evolution of Asahi/Pentax normal primes (optical side approach only) from the earliest Takumar to the latest Pentax FA 50/1.4.

Thanks in advance.

have you tried writing directly to pentax?

Yes I did. They sent me from one to another a few times (in about one and a half months) and finally someone answered me to apologize as they cannot disclose this type of info.

That's a crap, as the most of the newer Pentax lenses have been released along with their optical formulas. On B.Dimitrov site you can find almost any formula since the K-mount.

For books, check here for authors Van Oosten and Cecchi.

Books

Cecchi gives a good overall view and Van Oosten a closer look at the lenses. Another good place for checking M42 lenses is:

The Ultimate Asahi Pentax Screw Mount Guide
by Grejan van Oosten
is the only complete source of optical diagrams and covers lenses from 1952 to 1977. It is a lot of fun following the design path for various lenses.

Later lenses are covered in Boz's Welcome to Bojidar Dimitrov's Pentax K-Mount Page K mount site.
