Before answering the question 'what are the best binoculars (UK)' I need to make it very clear that a good pair of binoculars is something you can and should get really passionate about. The best binoculars bring distant images to life with amazing resolution and clarity making you feel as if you are part of a completely new and exciting world.
Imagine being able to see every little detail of what you are viewing with absolutely perfect contrast and clarity no matter where you are and what you are doing. If you experience such perfection you will become passionate and you'll wonder how you ever lived without the very best binoculars. UK binoculars do vary from what is available in the US and the two environments are completely different so the best binoculars in the US may not be available in the UK or may not perform so well under the different environmental conditions.

You also have to consider that people's opinions vary, sometimes quite dramatically, so what each person considers too be the best binoculars is probably not the same. Also, you need to be clear as to what you want to use the binoculars for, the best binoculars for astronomy won't necessarily be much good for bird watching and the best sport binoculars won't necessarily be very good as marine binoculars.
