The 7mm fully dilated pupil (night vision eye capability) isn't achievable by everyone and will get smaller with age. It may be preferable to have a number of different sets of binoculars for use for different circumstances rather than have a very expensive single set trying to cover everything.
I have a pair of Bresser 8x56s (Meade of Germany). They are heavy @ 1.1Kg and quite bulky, have quite a narrow field of view @ 101m/1000m, but they are exceptional for low light conditions with that 7mm exit pupil and the light gathering 56mm objective lenses. They cost me around $75 from a discount store called Lidls. They will for example beat even Nikon Monarchs 8x42s in low light conditions.
Bresser 8x56s identical to these.
A more portable set of binoculars might well be these
BARSKA Naturescape 8X42 Waterproof Binoculars. I have found these to be excellent general purpose use binoculars. Again considering the cost these are a bargain @ the price shown. Weight is 600 grams.
I have also found these
Olympus 8x25 PCI Binoculars to be excellent considering the weight and cost (paid around $60 for them). In terms of performance/weight @225 grams/price ratio a candidate for the BOB.
Looking at the prices being paid online for some very credible high performance optics, overall there are some very good price deals around especially for the lower magnification/wider exit pupil binoculars (hence low light use at dawn/dusk). Why are a set of 16x50 Nikon Aculons considerably more pricey than a set of 7x50 Nikon Aculons is a bit of a mystery to me. i.e. Current Amazon.com prices;
Nikon 8247 ACULON A211 7 x 50 Binocular (Black) - $87
Nikon 8250 ACULON A211 16 x 50 Binocular (Black) - $136
Does the purchasing public think magnification is the be end all to purchasing binoculars?
