I have checked the 1938 Zeiss Ikon Hauptkatalog and a number
of other contemporary sources and although there are pictures of the Sonnar 4/7,5cm
lens for the Tenex II, I have failed to find a lens schematic.? However the January 1940 Zeiss ikon brochure ¡®3
Movikons¡¯ does have a schematic for the Sonnar 4/7,5cm lens for the Movikon
range of cine camera and I have added a jpeg of the relevant page to the Photo
directory in ZICG.
