===== Pentax 67 SMC Takumar 800mm f/6.7 ED [IF] ===== 
{{ :lens:pentax800mm6x7f6.7edif.png?400|}}
==== Summary ====
This supertele for the Pentax 6x7 system is a modern optical construction with internal focusing and two lens elements made from low dispersion glass. It was supplied with a 1.4x rear converter. With the converter you get the equivalent of a 1200mm f/9.5 lens. There is conflicting information about the optical construction. Pentax Canada says 11 elements in 9 groups whereas various other sources say 9 elements in 8 groups. The latter is supported by the one and only optical diagram PentaxForums have been able to find. If you have definite information on the optical formula please let a forum administrator know.\\
