In them concerning binoculars mount classical, there are several recommended models: 8 56 SWAROVSKI SLC, STEINER 8 X 56. In compact mount, with the advantage of smaller dimensions, the proper selection is wide: LEICA 8 X 50, ZEISS 8 X 56 VICTORY FL, SWAROVSKI SLC 8 X 50, 8 X 56 OPTOLYTH (excellent quality/price ratio). An alternative to consider is the Special range of 7 increases and front lens of 42 models mm, that maintains the same high luminosity than previous ones with a lighter weight (and smaller increase). Among them will be highlighting: SWAROVSKI SLC 7 X 42, ZEISS 7 X 42 VICTORY FL, OPTOLITH ALPIN 7 X 42.
