Papilio is the Latin word for butterfly, and this PENTAX Papilio 8.5x21 Binocular (62216) is an ideal companion for observing insects, museum artifacts and butterflies at incredibly close range.

The close focusing capacity of a binocular is in some measure quite limited by the position of the objective lenses themselves, but this particular Pentax has a unique Convergent Lens Optical System which brings the objective lenses closer as the focusing dial is adjusted to shorter distances. Thus the left and right fields of view are once again aligned, and the end result of all this is that you can have razor-sharp observing at just 1.6 ft.

The optics are fully multi-coated to eliminate harmful ultraviolet rays while improving light transmission. This gives you high contrast images with no glare or flare. The Papilio uses high quality BaK-4 prisms to transmit more light at the edges of the field. This enhances the illumination for easier viewing in dim light.

The body is a reverse porro prism design, in which the objective lenses are closer together than the eyepieces. This allows for nearly full-size binocular performance from a very compact body. A soft touch dark grey rubber armor with molded-in thumb grooves covers the durable and lightweight molded polycarbonate body to protect the internal mechanisms and provide a sure grip.

For extended hands-free viewing from a fixed position, you can mount the Papilio on a camera tripod using an optional tripod adapter and the standard 1/4"-20 thread tripod socket located underneath the binocular body. The supplied soft case has a belt loop for no-hands carrying. The woven neckstrap is 3/4" across, not exceptionally wide, but more than comfortable for all-day use with the lightweight (10.2 oz.) Papilio. An eyepiece rainguard completes the supplied accessories.

Pentax offering the PENTAX 10x42 DCF HRc Binoculars (62554) are full-size binoculars in a non-waterproofed package which shaves a bit off of the weight and price.

Pentax Binoculars have quality optics and great performance making them perfect everyday binoculars. Fully multi-coated lenses provide maximum light transmission with little glare. Phase-correcting prism coatings provide high contrast and resolution. This is particularly visible when looking sunwards, where more color and detail is visible in the shadowed areas of backlit or silhouetted birds.

The roof prisms are silver-deposited to reflect more light through the prism glass for a brighter image. The inert nitrogen filling of the binoculars helps keep the silver prism coatings from tarnishing.

Chromatic aberration is very minimal, on a par with binoculars considerably more expensive than this very reasonably priced Pentax. Astigmatism and geometric distortion are both well controlled. There is some minor curvature of field, so that the edges of the field are not focused as sharply as the center, but it is generally visible only at the far edges of the field.

The 10 x 42mm DCF HRc is very light in weight for a full-size high power binocular (only 23.3 ounces), making it easy to carry for all-day birding sessions. Despite its light weight, it is well-balanced and easy to hold steady, with few hand tremors to mar the view (even during long unbroken observing sessions).

This binocular is a sensibly-priced high power binocular with features and performance that can give quite a few more-expensive binoculars a run for their money. It is a binocular that most long-distance birders would be happy with for years to come.
