The Pentax 62608 UCF 8×25 Waterproof Binocular is an amazing instrument sold at an astonishing low price at Amazon. This binocular boasts fully multi-coated BaK4 lenses with aspherical eyepiece lens elements for edge-to-edge sharpness, at the same time having a JIS Class 6 weatherproofing. How in the world can a binocular of this quality be sold for around $100 at Amazon? If ever you’re looking for a real bargain, this is it!
The Pentax 62608 UCF 8×25 Waterproof Binocular has a single body housing. Adjustment to interpupillary distance is not done by adjustment of the two barrels as in all other binoculars, but by a synchronized eye-piece adjustment facilitated by a revolutionary dual-axis design. This also means that the focus system is also different from other binoculars, being done inside the solid housing, an “inner-focus system”.
With dimensions of 4.5 x 4.3 x 2.8 inches and a weight of 12.3 ounces it is a true pocket binocular, in spite of having a reverse porro and not a roof prism design.
