I wonder what is the most faultless binocular brand or model? I have been reading some american optics site,and some guys often says that Swarovsi bins are more exposed to failures as fogging. And that Leica has least failures.One guy who says he has inside information wrote:"..the Swaro's EL are known to corrode over time and loose their nitrogen charge"
I suspect this to be only rumours.
I've always found people who've had 7 x 42 Zeiss love them. I used them for 13 years incl very hot places, very cold places, very dry places and also in the tropics - once for two years). They are still mechanically excellent, in very good shape still and perform very well optically. Many of the newer bins haven't been round long enough yet for an objective view on their ruggedness in the field.......
I expect the Leica 8 x32 have a good record?
And yes I've heard of the fogging in the Swarovskis. I mentioned before a friend's had three pairs fog in Peru.
Leicas for me.. on the optical quality.. I can handle a few ergonomics faults when the image is THAT good
