Thought of another thing to add. My hunting partner has the Zen Ray Prime 8x42 binos. I personally don't like the eyecups but they are darn impressive glass at a much lower price. His 8x stay with my 10x Zeiss until the very end of light in our side by side comparisons. They have an exit pupil advantage being 8x instead of 10x so it isn't an apples to apples comparison but they are still impressive. I haven't seen anything better in their price range.
