The Meopta Meostar B1 is a 10 x 50mm Waterproof & Fogproof Wide Angle Roof Prism Binocular. When you prefer a big, bright view that's as uncramped as it gets and don't mind the extra mass and weight which must come along with these demands, you'll want a binocular such as the Meopta Meostar B1 10 x 50.
This is by no means a small optic, one much better suited to carrying all day via a well-padded case supported by your chest as opposed to upon your neck with even the best of straps. But the difference between a premium 10 x 50 and even the upper echelon of 8 x 32, 8 x 42 and 10 x 42 offerings is quite apparent. The 10 x 50 has that brigher edge, along with a background that will be brilliantly blurred behind the subject. Thus observing a subject cast below a thick tree canopy will be no problem at all; it stands out even in poor light, with the coverings afar simply blurred out of focus. For a select few, this will always be the view that cannot be denied versus the convenience of a 42mm optic.
