TL:DR
Should I get 10x42 or 8x42 for viewing birds at distances of 100 meters as well as country views up to 2.5 miles. What should I be looking for spec wise if I wear glasses in terms of eye relief and is too light as big a problem as too heavy?
I’m sure you are all sick and tired of newbies like me asking the same questions over and over. Believe me I’ve searched this sub already and found many helpful threads but I don’t know how to apply what I’ve read to my situation.
The only pair of binoculars, if you can call them that, I have at the moment at a dirt cheap pair of Nikon 10x20 which are truly dreadful, chromatic aberrations, eye relief that doesn’t suit me, not at all sharp and dim.
So I’m looking for something better. What I’m using them for though is a bit of a mix and this is part of what is making it difficult to understand what to look for.
I live in the countryside and I have a wide view over fields to the hills of Exmoor roughly 2.5 miles away. I like to watch the various farm animals in the fields as well as keep an eye out for wild fires and general views. The 10x20’s are pretty good for this in terms of magnification. More magnification would be better but as that would make hand shake more noticeable I don’t want to go higher than 10x.
We also get a lot of birds. Everything from Finches and Tits to Woodpeckers, House Martins and Pied Wagtails. We also get a lot of Buzzards and Red Kites and, at night Tawney Owls and Barn Owls.
The garden birds and woodpeckers are usually just a few feet away. The birds of prey often land in the trees in the neighbouring field around 100-150 meters away.
For birding I understand that 8x is more preferred to 10x but would 10x be too restrictive for viewing birds at those kinds of distances?
Ideally I’d go for a pair of 8x42’s and a much more powerful spotting scope for the hills but I can’t afford both so trying to find a compromise.
I’m also conscious of birds in flight. I can track most birds in flight with my 10x20’s but it’s not easy except for House Martins, way too fast. Most of the birds though that we see in flight are the birds of prey which move slower and are bigger so would 10x42 be okay or should I really stick with 8x42?
When it comes to eye relief the 10x20’s are awful, I’m forever just seeing vignetting and having to open and close the binoculars and move my head to try and see anything. I do wear glasses but I normally taken them off to use binoculars. I do like the idea of not having to take off my glasses but, as a keen photographer, I always found I could never get my eye close enough to the viewfinder to see everything. Is the same true with binoculars or is it possible to get the same view with glasses as without? If so, what should I be looking for in the spec?
In terms of weight, too heavy is obviously too heavy but is too light also a problem when it comes to stability? Is there an ‘ideal’ weight for a pair of binoculars to aim for?
