## Description

The PENTAX papilio II is a very special binocular. This binocular has been designed to give nature-lovers a close-up capability. The working distance for macro-range enthusiasts starts at just 50 cm. We might have christened it a "magnifying glass" even though it is something different but no worries, it also ranges to infinity. Thanks to the BaK4 prisms and multi-layer coating of the lenses, the papilio delivers a clear and high-contrast image. Furthermore, the inner focusing ensures a long working life and the aspherical lens elements in the eyepiece area achieve outstanding edge sharpness. Nothing that "creeps and flies" escapes the papilio "magnifying glass" - butterflies, beetles, spiders, flowers, pollinating bees or any other sort of fascinating insect. The rubber armoring protects the binocular against impacts and at the same time ensures a secure grip. Features the PENTAX-developed convergent lens optical system engineering mechanism, which automatically slides the left and right objective lenses toward the center 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. It is used for bird watching, traveling, sports and theater 50 cm close-up viewing for museums bright and clear.

Review: Exceptional quality small binoculars - From the moment that the box is opened, it is obvious that these binoculars are designed for the field naturalist. A snug rainguard style eyepiece lens cap that attaches to the strap is included, and the strap attaches by a secure clip-in mount. The strap is adjustable and comfortable. The binoculars are not quite as small as the more usual straight-tubed compact models, but they fit in a larger coat pocket easily, and are light and comfortable to hold. The distance between the eyepieces is easily adjusted to match the user, and they hold that position whilst in use. They feel like normal, full size binoculars in use - without the bulk. The optical performance is extremely good. They have a flat field of vision that is reasonably wide (the field width is slightly smaller than full size binoculars but still perfectly usable), there is no colour distortion, and the image is crisp right to the edge of the field. I have found the image of the 8.5x model to be plenty bright enough for normal viewing. The binoculars are suitable for birdwatching. I have tested them on overflying finches during visible migration and found the view allowed plumage detail to be clearly seen allowing confident identification of the species. The close focus is simply spectacular. They really do focus down to your hand! I have used them to study the structure of the antennae of flies resting on vegetation. I would recommend these binoculars as the optics of choice from all available on the market for observing insects. The only down-side is that they claim not to be waterproof. I have not tested this (for obvious reasons) but I did not notice any internal fogging when a light rain shower fell on them. The soft case that is provided fits snugly, can be applied whilst the binoculars are carried and provides good protection from showers. These binoculars are not only exceptional value, they are also of exceptional quality and would provide many hours of enjoyment viewing wildlife of all types.
Review: Good Quality - Good magnification, clear bright objectives despite the small size. Close viewing, eye relief good enough. As bright and clear as some 50mm binoculars I've had. Good magnification (almost 12) but big enough field of view especially for 21mm objectives. Objective lenses well protected, focus easy, not too loose or tight. Will focus as close as 50cm. Very light and at well worth it at -41% off normal price. Happy with these lightweight bins. Wasn't a fan of the carry case, but I had a Digital camera case that was a good fit and would protect better.

### ⭐⭐⭐⭐⭐ Incredible!
*by S***V on 27 May 2022*

These binoculars are incredible, my Dad has a pair of pretty expensive Swarovski binoculars 8x25 which made me get into looking for a nice pair of binoculars, after buying some cheaper ones 10x42 from Amazon, which really disappointed me with how dark and poor the image quality was despite looking great in there description, I decided to order a pair of these Pentax Papillio 6.5x21, I am so very happy and pleased that I decided to spend more money to buy these binoculars! The image quality is absolutely brilliant, so bright and sharp, and to be honest not really far off my Dads much more expensive Swarovski ones, I am really glad that I went for the 6.5 zoom, and not the 8.5, the image always looks so bright, and also the better field of view is very stable, and really good to find and track objects of interest. I really like how they feel, one handed operation is so easy, they feel great to hold and use. The strap is high quality, the eye cups go onto the strap so well, the twist out eye cups feel great to use. I love the design, its different from anything else out there. I love the case, the binoculars fit inside so well, I put cleaning cloths at the bottom and they sit in there so well, when the binoculars are in the case and it is closed with the strap on the outside of the case it is very easy to use them to carry the binoculars in the case so easily. The close up zoom is amazing, I was using it to read a OS map earlier today, and it made it a joy, I am a very fussy and I suppose been honest pretty hard to please customer, but I am extremely happy and delighted with my purchase from you, I can do nothing but recomend this extremely well made quality product, thank you very much.
