Sorry, perhaps this has been covered somewhere else, but I bought a pair of Trinovid 10x40B Portugal binoculars recently and I've noticed that doing the flashlight test through the eyepiece, one of the barrels is fogged slightly. To be honest, I don't know if I can tell when I look through them. Sometimes I think I can but it's extremely slight degradation of image quality if anything. But perhaps it might get worse? I don't know if I'm using the term 'fog' correctly, but I don't think it's fungus but I don't have much experience with that with my vintage Leica camera lenses, thank goodness. It just looks a little hazy. I still have time to return them if the fix might not be too expensive. I do love them, plenty sharp and bright and to be honest, I just love the look. If they just focussed close enough I'd keep them anyway! Thanks for any thoughts...
