Do also bear in mind that binocular technology has come on in leaps and bounds over the last 15 or so years, with modern lens and prism coatings now being far better (and significantly more affordable) than they were, certainly within the budget to mid-range price sectors. I think a lot of people would be very surprised if they looked through a pair of 'modern' binoculars costing within your budget, compared with their old 'named' models from 20 or 30 years ago.
I remember asking a professional ornithologist colleague about binoculars when I was looking to upgrade around 12 years ago, and he suggested a certain make which had a fairly good 'budget/low mid-range' reputation. As they'd been around a few years I decided to do some internet research, mainly to see if I'd be better biting the bullet and paying around £1000 for a good
second hand pair of Swarovski. That's when I found out about the Mk1 Hawk Frontier EDs (which had just come onto the market and were causing a bit of a stir in the birding world at the time) so I decided to take a chance on them.
A short while later I got chance to compare them with my colleague's Swarovski 8.5 x42s, and he got chance to try mine... and he went rather quiet! Yes, his Swarovski binoculars had a very slight edge on brightness, but I had to look hard to see it. Bearing in mind the Hawkes cost less than £300 and my colleague's Swarovskis cost around £1300 at the time, this apparent slight difference in performance would have previously been unthinkable.
Don't get me wrong, if I used binoculars every day for work, or bird watching was my main hobby, then I'd pay the £1700+ for top of the range kit (as I know I'd come to appreciate the slight optical advantage they'd give me, and they would probably last me many years of fairly constant use) but for what I need, and the image quality they give, then I'm sure I made a sensible choice.
