Contax was the favorite for action shooting, and low light. In the era of EI 12 film
and uncoated lenses, the f/1.5 Sonnar opened up the world for Contax shooters.
Bertele's designs made fast lenses with fewer air-glass surfaces,
so there was simply more light transmission and less flare.
There was no other choice.
But as for finding out who shot what, you'll have to start digging through annuals,
and bound magazines.
