Is the optical formula of Takumar 500/4,5 the same as SMC 
PENTAX 1:4.5/500?
http://digilander.libero.it/aohc/tak05e.htm says 4 elements in 
4 groups for Tak and so does 
I found this diagram (and many others) in the book:
The Ultimate Asahi Pentax Screw Mount Guide by Gerjan van Oosten.
http://www.bdimitrov.de/kmp/lenses/primes/extreme-
tele/K500f4.5.html for K 500. But is the optical design the 
same? If not, where I can find the optical diagram for Takumar 
lens?
Both lenses share the same diagram !

 The subject says it all. I really need this info quick - I found only one
 opinion on Stan's site.

In France 120 EUR (+/- 120 $), so 90 = good price.

But with K and M lenses you could not use matrix... just central or spot
..

Yes, K/M lens could use matrix metering, see:
