Not only birds, everything in life.I'm primarily interested in optics for the optics themselves, and the powers of 'supervision' that they provide. I'd imagine that most people here are into binoculars because they like to watch birds, etc., whereas I'm into birds because I like to use optics - I have to use them look at something! I wonder if that is a common experience?
Other tourists carry cameras, I carry binoculars, and while they are busy photographing, I am busy seeing.
I see ever so much more than they even realize is there.
