Nice for butterflies and birds - 11/25/2009

These binoculars are great. They are lightweight and easy to carry. These traveled along on many hikes when I lived in Arizona. The optics are sharp and bright. If they were fully weatherproof these binoculars would deserve the highest rating. Because of the fog and drizzle in San Francisco where I live now I tend to keep these at home and don't give them the use they deserve.

I recently purchased a pair of the Pentax Papilio binoculars sold by Eagle Optics. WOW! they are great. They are particularly good for looking at the fine details of VERY close objects such as butterflies, beetles and other insects. They are also great for checking out spiders and bees sitting on wildflowers. Pentax says they focus down to 18 inches and BOY do they ever. They do great for birding in the woods as well although for shore birds and other waterfowl I would recommend a full size pair of binoculars. I love my Papilio's and would highly recommend them to any nature lover.

Easy to carry - and see - near and far - 07/31/2009

The lightweight 6.5 and 8.5 power, 21mm Papilios use an internal focusing system that converges the objective (front) lenses to give a good image as close as 1.6 feet. That is close enough to see the details of a bee's pollen combs and antennae, or the lacework of a dragonfly's wings. At close distances the magnification gets a boost from the internal focusing and the 6.5x21 covers an area about the size of a postage stamp. This close focusing is the novelty that really sets the Papilios apart even from some small roof or reverse Porro binoculars that can get as close as 3-5 feet. The Papilios can even be used as a stereo microscope with the good built-in tripod socket.

The views at middle and long range do not disappoint. I watch backyard mockingbrids, finches, quail and the occasional roadrunner and red racer snake or lizard in sun or shade from back porch. These are light for dayhikes, and also do a good job looking into shadowed areas beside washes or up at petroglyphs on rock walls. They cleaned up fine after a cold and windy whale-watching trip with occasional spray wiped with a sweatshirt sleeve (they are not water proof!) and they gave better views than an inexpensive 7x35 Porro also used on that vacation. At night they give passable views of the moon.

If you are considering compact binoculars be sure to give the Papilios a look. I chose the 6.5x because I wanted the plus side of 3mm exit pupil, and their brightness proved fine for shared family use. If budget allows I'd buy a second pair, another 6.5 or perhaps the 8.5 if budget allowed, because they are so well suited to family hikes and nature observation.

Likes:

- smooth, precise focusing action
- click stop eyecups and diopter stay put
- good surface material, comfortable to grip
- pleasing views near & far, 'macro' to moonrise
- built in tripod socket works well
- clear daytime views even into shaded areas
- 'standard' ~ 50° apparent field of view has sharp field stop, little drop-off at edges

Dislikes:

- eye lenses are not multicoated(?) and have reflections when the sun is at your side (cup a hand between the small binos and your sunward temple to solve this); this is the most noticable distraction or fault.
- internal ghosts seen are when observing bright moon, moon is free from ghosts and sharp when placed just off-axis.
- eye placement is comfortable once set -- but IPD and eyecups need to be set 'just right' with that 3mm exit pupil and that takes a moment switching between each family member.

My basis for comparison, and saying that the Papilio views are fine, are a few older 6x to 12x Porros and recent Bushnell and Minolta 8x42 roof and 50mm Porros.
