Re: Zen Rays
I have the ZRS HD 10x42 and the ZEN ED3 10x43. For the price the ZRS HD's can't be beat!!! The ZEN ED3's are only a slight upgrade from the ZRS HD's, mainly a slight bit better contrast and resolution as well as a slightly larger "sweet spot". They both handle stray light and CA about the same, the ED3's have a slightly larger field of view. I examined a set of Vortex Talon HD's at Cabelas last weekend, but an in-store review only told me so much. The Talon HD's are a direct competitor to the ED3's so I wish I could have taken to the field with them for a better idea of their standing with the other two.
Bottom line, I don't think there is any binocular out there that can compete with the ZRS HD's in the sub $400 category.
