so at twilight i wouldnt see any diffrence in a 3x10x42 than a 4x10x50?
A hunting partner of mine owns a 4x12x50,and comparing it to my own 3x10x42s at dusk and dawn, I certainly don't see a significant difference.The 3x10x42 is plenty bright for use during the legal hours where I hunt,that being 1/2 hour before sunrise to 1/2 hour after sunset.
