Macro and to the moon!

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 ??

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

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.

In Love

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.

Love the Pentax Papillo

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.

Great walk around bins!

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.

Papilio 6.5x21: Superb

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.

perfect for a photo walk

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.

Great Concept

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.

Unique close-focusing; better optics than original model

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.

great customer service and great product.

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.

Macro and to the moon!

By MONICA S.

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 ??

This Pentax binocular series is called Papilio, the Latin word for butterfly. PENTAX Papilio 6.5x21 binoculars are the perfect choice for insect observation in the field and in museums and galleries. The enhanced observation capability of the Papilio binoculars is made possible by a PENTAX Convergent Lens Optical System Engineering (CLOSE) mechanism. The CLOSE mechanism automatically slides the left and right objective lenses toward the center when the focus is fixed at a short distance.

Don't miss a moment. Indoor or out.
Suddenly so close you can almost touch it. That's because PENTAX quality and clarity are within reach, at a price that's within reach, too. These compact porro-prism models feature a dual-axis, single body design with synchronized eyepiece adjustment. Aspherical lens elements give you edge-to-edge sharpness. Clear images and clearly affordable.

Fully multi-coated optics assure maximum light transmission resulting in high-quality viewing. Every surface of every element is fully coated minimizing internal glare and flare and giving a bright clear view.

Unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronizing the eyepiece movement. This minimizes moving parts and assures these binoculars will function properly and clearly for years to come.

Aspherical lens elements, which are critical in compact binoculars, provide exceptional edge-to-edge sharpness. This assures that items on the edge of your field of view are just as sharp as those in the center.

The UP 8-16x21 Zoom and UP 10x21 and 8x21 models are offered in unique, attractive color options that match your personal style.
