Binocular Double

An ingenious solution to the problem of super close focus: The Papilio by Pentax

Introduction: The best among the best   in ability to focus very close are the  Alpen Apex 8x32, the Columbia Backcountry 8x25 Pocket Roof Prism Binocular and the Eagle Optics Ranger STR 8x32, as well as the Zumell Signature 10x42 and Hawke Endurance Close Focus 10x42, both normal size binoculars. These binoculars can focus on an object as close as 3.3 to 4 feet (1 to 1.2 meters), which is unequalled and makes them perfectly fit for observing insects like butterflies and dragonflies.
If it's exceptional being able to focus as close as 1 meter/3.3 feet, what superlative words can be found to describe the ability of the Pentax Papilio, with its close focus ability of 18 inches(46 centimeter)?

The problem with focusing really close:
Binoculars are actually two telescopes working in unison. Each objective lens delivers a distinct image to its eyepiece. This means that the viewer actually receives two different images through the eyepieces. However, in his mind these two images are integrated into one – as long as viewing something not up close. However, the closer  the object, the more difficult it gets to integrate the two images, until it is not possible anymore. Most manufacturers limit the close focus to the closest distance at which the two images overlap.  As said above, this could be a close as 1 meter. However, some of these super close focus binoculars do give you focus at such close ranges, but the images from the two barrels/telescopes are not entirely integrated.

What is the solution to this problem presented by Pentax?
Pentax's solution to the problem is a groundbreaking new technology known as CLOSE : Convergent Lens Optical System Engineering. The key to this technology is the fact that the objective lenses and the eyepieces are no longer in the same housing; the objective lenses are placed in a solid housing separated from the eyepieces. Adjusting the barrels to fit your eyes has no impact on the position of the objective lenses, as in the case of all other binoculars.
For focusing you use the knob at the top between the eyepieces. Focusing is done by moving the lenses closer or further apart from one another and not, as in the case of other binoculars, by moving the lenses closer or further away from the eyes of the viewer.

Ever noticed that the objective lenses move further away or closer (or the eyepieces) when you focus with an ordinary pair of binoculars? Well, with the Pentax Papilio the objective lenses themselves converge on one another within the solid housing when you're focusing. The closer you get with ordinary binoculars, the more difficult it gets to integrate the two images from each telescopic unit, until it's not possible anymore. Not with this binocular. Since the two lenses move closer to one another, converging the two images is no problem for the Papilio – not even as close as 46 cm! No double or half-overlapping images at such a close range – one single integrated image. And that without any special effort from your own eyes!
The closer the object on which you are focusing, each eye's line of sight converges with the other's, so you're constantly looking at the same object with both eyes.
Overall size:
The Pentax Papilio is a compact binocular of the "reverse porro" type, 4 inches long and 4.5 inches wide, weighing only 10.5 ounches. The size of the apertures is 21 mm.
Different models:
Two models are available: The Pentax Papilio 6.5 x 21 and the Pentax Papilio 8.5 x 21.
Different applications:
"Papilio" is the Latin word for "butterfly", so Pentax clearly developed this instrument as a specialist instruments for super, super close viewing of insects like butterflies. In this regard it is unrivalled. The only limitation it has as far as viewing objects close and far away is the size of the apertures (21 mm), but that applies to all compact binoculars in any case.
