Customer Reviews

Up close and personal
I had been looking for some time for a set of compact close-focus binos for butterfly and moth observation, and as a light-weight backup when not carrying my birding glasses, when I stumbled upon the Pentax Papilio.

I am astounded at the close-focus capability of these glasses. There is, quite simply, nothing on the market in the same league. At 8.5x21, the exit pupil is quite small and it required a little bit of patience to get everything adjusted to my liking. The payoff was well worth the initial trial and error tinkering as I was introduced to a new world of close-up nature observation.

At long distances, there is a slight bit of noticeable chromatic aberration, but well within the range of acceptability for backup use and probably acceptable for most folks for general use. There are a lot of fine field glasses available for different purposes - if close focus is the most important feature for you, you will not be disappointed with the Papilio's.

Beautiful but they make me feel stupid
Read all the rave reviews and bought. They're beautiful and well-made, light and feel good. So why do I feel stupid? Because, for the life of me, I can't read the instructions and, therefore, can't make them work. Does anyone have a "How to use your Papilios for Dummies?

Thanks!

Wish we could see this way all the time!
I agree with all the positive reviews on the 8.5x papilios, I feel like a kid again exploring the backyard. The close focus really is amazing and the far focus is like any other quality binoculars. They are tiny, a true work of optical engineering.

My gripes - I was disappointed to open them up and smell that familiar Chinese rubber/plastic stink. It faded some after a few days of airing out in the sun. The reflection/glare from side light bouncing back from the eyepieces ruined the pleasure of watching the little creatures go about their business. Agena astro's soft rubber 1.25 inch non-stinky (made in Japan) winged eyeguards made them much more comfortable and totally got rid of the glare. The diopter adjustments for the right eye are very subtle and took a while to get just right for my eyes, it was frustrating until I got them properly adjusted, but once there, they stayed in focus and the details of true stereo vision jumped out to me.

Before using (and properly adjusting) these I don't know if I would have paid the few hundred dollars list price for them. I might have taken the gamble. But at the low price they're going for now, and with the Pentax $20 lifetime replacement guarantee, they're a steal. I can't imagine any adult or older child who enjoys nature who would not have a ball with them day after day.
