Sightron 8x42 SII Blue Sky Binocular
The 8 x 42 binocular platform is the one I use the most, for it offers a 5.25 mm exit pupil. Exit pupil is shown by the following graphic, courtesy of Olympus.
While like most things, it is a matter of personal preference and individual use, the 8 x 42 binocular set offers more image stability and image brightness than possible with a 10 x 42 set, and more brightness potential than the common 8 x 32 binoculars, with very little extra bulk or weight. The Sightron Blue Sky specifications are as follows.

Although I've tested, used, and hunted with Sightron riflescopes for many years I've overlooked their binoculars. If this Blue Sky set is any indication, it has been my loss. The hinges work smoothly, the eyecups stay where they are supposed to, the rubber armoring is very grippy and feels great in the hands. Preliminary focusing is quick and easy, for the diopter focus is located right below the center main focus knob. Rubber objective covers have often been a hassle, for they can easily pop out, fall off, and slide around. Sightron has paid extra attention to this with a one piece plastic objective cover array that pops securely into place and comes off quickly, with no potential to obscure vision from swinging cap syndrome.
is a bright, clear, comfortable set of binoculars that performs well outside
its price bracket and will leave you wondering why some $500 sets don't
have the image quality the $175 Sightron Blue Sky set has. There is little
that compares to these binoculars in their price bracket, and several
far more pricey sets do not compare favorably. There is little else to
say except that you won't be disappointed and congratulations to Sightron
for an outstandingly good set of 8 x 42s binoculars at an extremely appealing
