LEITZ TRINOVID BINOCULARS 
A Totally New Concept 
Wi 
v 
he 
Creators of the world-famous 
Leica camera have perfected 
a new. prism system that 
dramatically reduces binocular 
size and weight. It’s the first 
truly significant binocular ad- 
vancement in fifty years. The 
Trinovid 7x35 has an amazing 
450-foot-wide panoramic view- 
ing field at 1000 yards. The 
8x32 and even the 10x49 are 
more compact than conven- 
tional glasses of much lower 
power. And all Trinovid mo- 
dels have fast-action central 
focusing, are hermetically 
sealed, dustproof & weather- . 
proof.
