Hi David,
Are you a bush birder, a rainforest birder or a seabirder? Each different
type of birding is suited by different kinds of binoculars. As previously
stated 10x (which I use) are much harder to hold steady, and harder to
actually find birds with (you need to develop good technique in challenging
environments like pelagic boats and rainforest). 8x is easier to hold
steady, but doesn't bring you as close to a bird, so for small birds like
thornbills, or birds difficult to get close to you might prefer 10x. In the
end its personal preference, I've met a few birders who use 7x, and one who
uses 12x.
Regards,
Chris
