Re: Optical Formula of Takumar 500/4.5
Maciej Marchlewski a crit: 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 !

[EMAIL PROTECTED] a crit: But with K and M lenses you could not use matrix... just central or spot .. Yes, K/M lens could use matrix metering, see: http://www.robertstech.com/matrix.htm http://perso.wanadoo.fr/krg/Photo/multizone.htm Michel
