I was guiding antelope hunters this past weekend in New Mexico. I carried my Zen ED2's in 10x43 as well as my trinovids. There were three other pairs of binos in our group, two SLC 10x42's and a 15x56 Geovid. In a nutshell, the other three were astounded my Zen's had a better view than anything they had. Mine were noticably brighter and contrasty, and it rained off and on all weekend. No problems, fantstic views, even better than those SLC's and that big Leica by their own admission.
