Hi,
As you suggest, I think that 8x40s are the best compromise. Higher
magnifications are OK though it means you have to hold them that little
bit steadier. After you have been using them for a while you get better
at that. Higher magnifications also means smaller field of view and
harder to find the intended target quickly. Again after you have been
using them for a while you get better at that too. So, if you have to
ask the question I suspect that 8x40s are best. Otherwise you will
know, and have tried other's binoculars to help you decide, whether
higher magnifications are better for you.
High relief binoculars with the same size optics, naturally have a
narrower field of view. The only way to get a wider field of view is to
have bigger diameter and hence higher quality optics, particularly in
the eyepiece and prisms (ie it doesn't have anything to do with either
the 8 or 40 in 8x40). This means greater (usually significantly
greater) expense.
Cheers

I have read many articles about choosing binoculars, and most seem to
suggest that 8x40 is the best compromise between magnification, field of
view and weight for birders. One article even suggested 7x or even 6x
in order to get a better field of view. But I've been surprised how
many birders seem to use 10x. What do people recommend?
I've also found it a little perplexing that many high relief binoculars
(I wear glasses) have a narrowish field of view to begin with, so what's
the point? And don't get me started on the amazing price variations
between dealers, and that fact that many are unable to convert between
the different FOV measurements.
