Named after the Latin term for butterfly, these binoculars are specifically designed to bring the intricate details of the natural world into sharp, clear focus. Engineered with the innovative PENTAX Convergent Lens Optical System Engineering (CLOSE) mechanism, these binoculars boast exceptional close-focusing capabilities. This feature allows you to observe the minute details of insects, flora, and artwork as if you were standing mere inches away. The Papilio II series is renowned for its weather-resistant construction, ensuring reliable performance across a variety of outdoor conditions.

These are my absolutely favorite binoculars ever! Not only can you sneak a peak at the moon ? but you can zoom in on the wonderful macro world of insects or miniature flowers that these old eyes just can't focus on anymore. They are compact ! They are lightweight! They are just absolutely wonderful worth 10 stars ??

Macro and to the moon!

Very happy with Pentax 8.5x21 Papilio II. I purchased it to carry in field for close focus in identification of butterflies. It?s lightweight, easy focus and best of all waterproof.

I would recommend product. It?s well made, rugged construction for any conditions you encounter in the field.

I love these binoculars so much. I get to watch insects, lizards, and other small critters without getting all up in their space. They came so quick, too! I love them.

In Love

I bought the originals of these years ago and misplaced them. I recently bought the Series II and they are noticeably better-just as good at close-up viewing as the old ones but superior for distance viewing. I compared my 6.5x with my friend's 8.5x and I prefer the 6.5x, which as a slightly better depth of field. 

I took my two sons with me to the Met. Museum of Modern Art in NYC and was astounded at the miniature art using these binoculars. For example, Jan Van Eyck's The Crusifixion; The Last Judgement, I could see the detail in the faces in the foreground.

My wife confiscated these from me and wont give them back.

Love the Pentax Papillo

A gift for my wife as we?ve become avid hikers and bird watchers. She loves it

Bird lover

Compact, lightweight, easy to use, good field of vision, great magnification of small up close objects!

I think I'll buy another pair for my wife.

Love these binoculars- light weight, easy to use and have great capabilities!

Love butterfly binoculars

Butterfly monitoring so much easier

I'm a retired snowbird and these little binoculars are perfect for walking on the beach.  They allow me to look at shells, crabs and jellyfish without squatting.  They are great for butterflies and wildflowers, too.  The big surprise though is that they work really well for birds, boats and everything else.  I used to have the original version but I don't have them now to do a side by side comparison to the version II.  But based on my memory, the version II has considerably better optical quality.  I recommend the 6.5x over the 8.5x.  They are easier to hold steady and have a bigger exit pupil which makes for a more comfortable view.

Great walk around bins!

I have several sets of the Papilio 6.5x21 binoculars.  The wide field of view and close-up focus make them especially useful, both for nature-watching and for lectures, etc.  I have a visual problem (wear special glasses)and find them extremely helpful.  For the price (or even for a lot more) they are uniquely helpful.

Papilio 6.5x21:  Superb

I am a birder and nature photographer. These are extremely sharp for macro and at least as sharp as my 8-42 monarchs for birding, just not as bright. Very compact and light. I love the fact the case has a belt loop. These binoculars stay out of my way when I am taking photographs.

perfect for a photo walk

I purchased these binoculars for an upcoming trip to Costa Rica.  So far, sighting them in for my eyes and use around the neighborhood show them to be light, easy to focus and well-suited for short to close-distance observation.  In my childhood, living in Perú and Venezuela and seriously engaged in entomology in the rainforests, I had considerable experience observing insects and other wildlife, but only with the naked eye.  I hope to expand this experience in Costa Rica with the power of these binoculars.

Great Concept

Close focusing maintains stereo vision down to 1.5 ft. without readjusting interpupillary distance.  Comparable to a long-distance headband magnifier.  Excellent optics for the price.  In poor light conditions, noticeably contrastier image than original Papilios.  Handy not only for insect-watching, but museum use, indoor architectural viewing, pole-pruner collecting, etc.  My favorite travel binoculars.  (OK for bird watching, but prefer my Nikon Monarch 7 8x30.)  Easy to hold, enough eye relief for eyeglasses.  If you own any other binoculars, a good choice for a second pair.

Unique close-focusing; better optics than original model

I am very pleased with this product when it finally did come.
The only hick up was, it was in stock and when I placed the order and confirmed it with my gift certificate the next morning, then they said it wasn't.
But I am very please with the product and Lewis who helped me on the other end of the phone with customer service.
