a little help.I'm looking to update my bins.something like a 10x mag with objective lens of about 20 to 40 mm.looking to use freehand for general spotting.I have a budget of about 100 gbp
I have a pair of Bushnell 8x42 h2O bins which I think are around the £100 mark, I have had them about 8 years now and for the money really can not fault them, nice sharp optics and a very smooth focus wheel, and waterproof too. I seem to recall that they made a 10x version too
i have a pair of Hawks and i love em, SWMBO has just bough a pair of Deltas, even cheaper than mine high, lighter, brighter and have a full lifetime guarantee, not bad. can't remember what she paid mind. but both are 10x42. for a comfortable viewing experience, this is as big as you want to go. unless you can shell-out for top end ED glass.
Another thing to consider is the diameter of the exit pupil of light.
It has to be smaller than the diameter of your pupil or else the image
will not be as bright as it could be and should be.
My Nikon Prostaff 82mm scope has a 7.6mm exit pupil of light.
My eyes are about 8mm or a little more, so I get to see all the collected light.
My 7x50mm Pentax binoculars are about the same.
On a hunting trip a few years back, I got to try out a pair of Zeiss (size unknown).
The image focus and brightness was a thing of beauty! Hate to say it but some days,
you really do get what you pay for.
It's a lot cheaper because it's basically only half a bino but nice and bright, coated lens and has a tripod if you need a steadier view. Mine lives on my desk by the window most of the time. It's a chunky bit of kit but not much more than a smaller pair of binos.
