I bought a pair of Vortex Razor 10x 42's last year after doing about 5 months worth of research, testing, reading reviews, and poking around on the internet. I looked through Zeiss, Leupold, Nikons, Steiners, and Leicas and bought these because, for my eyes, they worked the best.I took them hunting last fall in the Twisp, Conconully area and put them through my standard hunting - which means falling from rocks, falling from horses, hunting in rain, snow, dirt. I fell on them twice and dropped them once - no damage. They are outstanding in clarity. I'm not an optics expert but, after 37 years of hunting, I know what it means to look through a pair of good binoculars and these are just flat out good. I gave my old Bausch and Lombs (sp?) away and never looked back. Minor drawback is that the adjustable diopter cups are plastic when they would be better in an aircraft grade aluminum...and Cindy Crawford has a mole...so what?
I won't be looking for binoculars again.
