Remarks:
Roughly 30 years after having been brought to the market, the Leica Trinovid “BA” models still impress today with their sturdy construction and excellent optics. Some even consider the BA and BN Trinovids the best classic Leica binoculars, being for Leica what the legendary “Victory FL” binoculars were for Zeiss.
