RFI re 8x42 v 10x 42

["George Oakes" <>]

When I purchased new binoculars recently to compare 8 times and 10 times it 
was suggested to me that if a bird is 50m away an 8 times will bring it up 
to the equivalent of a little over 6m away while a 10 times will bring it up 
to an equivalent of 5m away. If you compare these distances of 5m. and 
6m.plus there is not much difference in looking at a bird.After taking into 
account such things as shake, field of vision, and weight I finished up 
buying an 8.5 x 42 binoculars.
