I remember my first pair of birding binoculars, over 30 years ago, a pair of so-called "East German" Zeiss! They were great, I saw many good birds, often "lifers", with them, but very different from the ones I use now... the state-of-the-art Victory SF 10 x 42. Still Zeiss glass, of course, but the technology has moved on a little! I flirted with two other binocular brands for a year or two (another German make and a Japanese one) but soon returned to Zeiss, using various models over the years. Here is the past and present, before and after, my first and my current pair.
