My first binoculars were DCF XP 10x33's so I decided to upgrade along the lines of a 10x bino to the ED 10x42's. They produce beautiful images in comparison to my old binos, but reading all the 8x rave reviews make me think i should have gotten them. I bird in all sorts of locations (marsh, forest, riparian zone, coast etc.). I sometimes carry a scope but not always. Should I try to exchange the 10x's for the 8x's?
