    Best high-end birding binoculars without "rolling ball" effect?

    Oh, but it will be as bright as the 42 equivalent, until the light level drops enough to cause your pupils to enlarge beyond 4mm; at that point the 42s will have the advantage. I have both 8x32 and 8x42 FLs, and in normal daylight they are equally bright.
