Product Description

Binocular Overview

The PENTAX Papilio series binoculars is not only designed for the observation of animals in the wild from great distances. If your preferences or requirements are for a smaller world, more near to hand – flowers or insects, for example – then the Papilio series is particularly well suited. That's because the focusing range begins at an impressive 50 cm, ideal for detailed observation, and the durable rubber reinforced housing makes the Papilio range a true friend of nature.

50cm Close Focus
50cm Close Focus
Effortless Close-Range Observation

The Papilio series features the Pentax-developed Convergent Lens Optical System Engineering mechanism, which automatically slides the left and right objective lenses toward the centre when the focus is fixed at a short distance. As a result, the right and left image fields are correctly aligned to facilitate close-range viewing. Thanks to its go-anywhere portability, this new series is also ideal for conventional binocular subjects, including spectator sports, travel and hiking.

Extra-Short Minimum Focusing Distance

The Papilio series offers a minimum focusing distance of just 50 centimetres (approx. 1.6 feet), considerably shorter than the two-meter distance (approx. 6.5 feet) offered by many similar models.

Aspherical Lens Elements Providing Edge-to-Edge Sharpness

Edge-to-edge sharpness is a vital element to comfortable viewing. To achieve this, Pentax utilises aspherical lens elements in their eyepieces. This is a specially shaped lens design that reduces aberration to a minimum. The Papilio series features multi-coated optical elements to minimise unwanted light reflections for a well-defined subject image. The combination of aspherical optical elements and high-refraction BaK4 glass prisms assures a sharp, clear image with minimal distortion, even at the edges.

High Quality BaK4 Prism

A prism is a complex optical element necessary to correct the image the right way up and reduce overall length of the binocular. In a prism, light travels through complicated angles and so the quality of the prism glass used is of significant importance. Pentax uses exclusively high-index BaK4 prisms, made of very pure Barium glass.

Protective Rubber Housing

The protective rubber housing not only protects inner mechanism from external shock, but also assures a firm, comfortable grip of the binocular body even in the field. The compact design offers you comfort in handling with perfect weight balance.

Twist Up Eye Cups
Twist Up Eye Cups
Twist-Up Eyecups

The binoculars have large, multi-stop, twist-up eyecups that can easily be adjusted to your desired position. They can be fixed in various positions, depending on the binocular model. Combined with a large-diameter eyepiece (ocular) lens and comfortable 15-millimetre eye-relief, it allows any user, even those wearing spectacles, to find a comfortable setting.

Inner Focusing

The Inner Focus function is critical to low-maintenance and long life guarantee. Exposure to airborne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the binocular housing and disrupt functionality.

Other Features
  • Pentax-original dual-axis eye-distance adjustment mechanism for quick, effortless eye-distance control
  • Extendible helicoid-type eyepiece rings with a single-action pop-up/storage mechanism
  • Diopter adjuster with a click-stop lock mechanism to avoid accidental dioptre shift
  • Neck strap with a quick installation/removal mechanism and a Tripod receptacle for stable observation

We've been waiting several months before submitting this review so we could give these Pentax 8.5x21 Close Focus Papilio Binoculars a good try out. And they are excellent. We've had several pairs of binoculars between us over the years, but these are outstanding - definitely the best. 8.5x suits us very well for general outdoor use, giving adequate power without the tremor effects that you can experience with the 10x or 12x types. Light .. powerful .. compact .. crystal clear images (as you would expect from Pentax optics) .. and an amazing focussing range - yes, you really can examine the grasshopper sitting on your shoes! and then see it clearly again fifteen feet away. The binoculars come with a snug detachable case, a neck strap; plus a double eyepiece soft plastic lens cover for protecting both eyepieces when not in use, it threads on the strap so doesn't get dropped. One eyepiece adjusts to accomodate differences in eyesight between your eyes. These are brilliant binoculars - we've stopped lugging our off-puttingly heavy and bulky old ones around with us now! Highly recommended.

Physically these binoculars are quite small, about 13cms wide by 11cms front to back, but their performance is huge. They are excellent at distance and through the range to 0.5m where they are fantastic. Retaining the binocular effect through internal shifting of the optics for near objects one gets a true 3D effect. I was looking at a Minox close focusing monocular but these are so much better. All the focusing movements are internal and the build quality is superb, as you would expect from Pentax, and a 30year guarantee(!). Complete with lovely case and quick fit strap. If you buy one you will not be disappointed.

I bought these binoculars to go on a wildlife watching holiday in the Catalan Pyrenees in Northern Spain, in addition to watching birds and butterflies we looked for wild flowers.I was thrilled to find that I could use the short focus binoculars to look in detail at the wild flowers.They acted as a magnifying lens, and I could stand and admire rather than lie down to get a closer look!
The binoculars are light and easy to focus, and the image is clear.
The only disadvantage is they are not ideal for bird watching, but I used other binoculars, they were purchased to look at butterflies,and for this they performed extremely well.

These are lightweight, compact and don't weigh me down on a long walk, so they are binoculars that actually get used. The image is bright and clear, with the close focus ability being far more useful than I expected, eg. perfect for that unusual butterfly that happens to land on the path in front of you. I think they're great.

Pentax 8.5x21 Close Focus Papilio Binoculars. Purchased these as lightweight, multi-purpose binoculars primarily to watch insects without disturbing them, look at small plants without forever bending down and also to look at birds etc when necessary. Although not the best for bird-watching, they are more than adequate but they are excellent for other purposes including butterflies and other small objects. Lightweight, easy to focus and excellent optical quality. I can stand up and get a great view of objects next to my feet or on a tree-trunk a few feet away[passers-by may think you are weird, but with a creaky back this is a fabulous feature]. A bit expensive but I have not regretted the purchase.

Theses are the best all rounders of our five binos and a Swarofski scope for long distance. Experience (and frustration) showed don't get zoom, it decreases field of view; go for a biggest objective that is not too heavy, and of course go for quality which is subjective and best judged by visiting a store (and subsequently buy from them - don't be mean use your local store or lose it!). I trusted a newspaper review to order these online unseen and am overwhelmed by the versatility, light weight, easy focus and high quality. The close up zoom never fails to get a "wow" from first time viewers. I now have an iterest in insects, didn't realise there were so many bees and false bees. See the hairs on the antennae of the buterflies, and of course see the club ends on butterflies and lack of on moths. See the water surface bend like a sheet of plastic under the pond skaters. Let the texture of rock and the subtle beauty of lichen and moss lead you to a world of aesthetic of the tiny. I wish I could photo the drop of rain that enclosed the tiny flower with the sunlight glinting off the sphere of water - I look forward to spells between showers just to see the art of nature in the minature. I know all flowers have similar reproductive parts, but we cannot them on small flowers - until these marvelous binos came along! I must stop gushing now, time to look at those birds on the feeder and see their tongue and tiny seeds getting chewed. The slight downside is the slightly less light gathering than my 8x42 Opticron or my 8x40 Helios but they weigh much more and are much more bulky so are often left behind, these are small enough to fit in a pocket and so get taken more often. Don't prevaricate, just get them! Delivery was on time good service.
