Close Focusing No Problem With The Pentax Papilio

Close Focusing No Problem With The Pentax Papilio

By:


Introduction:
The best among the best in focusing at objects real close by are the Alpen Apex 8x32 Waterproof Super Close Focus Binocular, the Columbia Backcountry 8x25 and the Eagle Optics Ranger STR 8x32, as well as the Zumell Signature 10x42 and Hawke Endurance Close Focus 10x42, both of which are normal size binoculars. An object as close as less than 4 feet (1.2 meters) can be focused upon by these binoculars, which is really exceptional and makes them perfectly fit for observing insects like butterflies and dragonflies.
If its exceptional being able to focus as close as 1 meter/3.3 feet, how are you going to find words for the close focus ability of the Pentax Papilio, which can focus as close as 18 inches(46 cm)?

The challenge of super close focusing:
Every binocular consists of two telescopes connected in such a way that they work together to give one image. Each objective lens delivers a distinct image to its eyepiece. Consequently, two different images reaches the eyes of the viewer. However, in his mind these two images are integrated into one as long as viewing something not up close. But integrating the two images into one becomes more difficult the closer the object he is viewing. Eventually it is no more possible. The closest distance at which the two images integrate in a natural way is where the close focus ability of most binoculars is set. As mentioned above, some binoculars have close focus distances as 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.

How did Pentax solve this problem?
Pentax invented a total new technology known as CLOSE : Convergent Lens Optical System Engineering. With CLOSE this Pentax binocular does not consist of two telescopes joined together to make one pair of binoculars; 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.
As in the case of all other binoculars the focusing mechanism is placed at the top of the instrument. The instrument focuses by moving the objective lenses not further or closer to your eyes, but by moving the lenses closer or further apart from one another.

Since the objective lenses are placed inside a solid housing, they start moving towards one another when the viewer focuses on an object. Using an ordinary pair of binoculars, focus on an object at a distance no problem; now get closer; still no problem; now real close by and youll see that the two images do not overlap completely. Then do that with the Pentax Papilio; no problem at all! Since the two lenses converge on each other, the two images overlap completely up to as close as 18 inches. 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 you focus, each eye's line of sight converges with the other's, so that both eyes are always looking at the same thing.

Dimensions
The Pentax Papilio is a reverse porro; it is a compact binocular (4 inches x 4.5 inches, objective lenses 21 mm) and lightweight (10.5 ounches).
Different models
Two models are available: The Pentax Papilio 6.5 x 21 and the Pentax Papilio 8.5 x 21.
Differents uses:
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 its specialized field it is unequalled. 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.
