It used to be that the 8x56 binoculars were the ones to go to if you were hunting in very low light or at night time - boar in Europe, for example.

It doesn't look like the alpha glass manufacturers are making them any more. Zeiss has their lower end Conquest 8x56, Leica doesn't make one and neither does Swarovski.

Swarovski has the EL in 10x50, Leica has the 10x50 Ultravid HD-plus and Zeiss has the Victory HT 10x54 and 8x54.

What is the reason for no high end 56 OL diameters? Are modern binoculars just so good that there is no need for the 56, even at night?
