Hunters, I have a question for you.
First of all CA = Chromatic Aberrations, or slight separation of colors observed at the edges of high contrast objects under bright light conditions. After blogging in some birder forums, I can see where binocular traits can be seperated out, at least my opinion is that the birdwatchers want, need, are incensed on having:
Birders need little CA since often they are watching birds fly or wade in water and and heavy CA can heavily degrade the image. Birders spend more of their productive "birding" time in the daylight and are often viewing birds when there is a fair amount of sunlight. Low light performance
Hunter on the other hand are after binoculars with similar but differing qualities. The following qualities listed below are my Rusty evalution taken from lots of other peoples inputs, and some of my observations (or, for what it's worth):
How important to Hunters, is a low CA, since most of the time (probably excluding observing caribou against a snowy background)? If possible, an ideal roof prism bino would have all these qualities, and no one could probably afford it. |

Sounds reasonabale to me. This is why birders and hunters don't always agree on whether or not a model or brand of bino is worth a crap or not.
