Papilio 8.5x21

I received the Papilio II 8.5x21, which is now fully multi-coated, and had a chance to use them for the past few days. I should note that I have never seen the first generation model, so I can't compare it to that. However, I can draw other optics that I have either used or own as a reference point - namely, the Zeiss Conquest HD, HT, Swarovski line of binoculars, spotting scopes, and rifle scopes, the Leica HDB binoculars, the Schmidt and Bender PMII line of rifle scopes, Vortex Razor HD binoculars and scopes and a myriad of cheaper hunting optics (Nikon, Pentax, etc).

The unit is compact and lightweight. The build quality is what would be expected for a binocular in it's price range. I doubt I would feel comfortable beating on these.

The binoculars fair well in the day time, but under dim conditions, they suffer.

The contrast, clarity, and colour are excellent for it's price range. I was very pleasantly surprised.

As others have mentioned, where this unit shines is close up. These are amazing for viewing the details on flowers, insects, or anything else for that matter. These have even impressed my friends that only use alpha-level optics.

One of the main drawbacks is that it is not a waterproof or fogproof unit. However, again, at this price range, that can be forgiven.

The biggest drawback to me is that the eye relief is too much for the eyecups. Even with the eyecups fully extended, I can't get a good view and have to brace the binoculars against my eyebrows. If this issue could be solved, I would rate these a 10/10 without hesitation.

I would highly recommend these to anyone that has an interest in looking at anything close-up. They are very unique in this matter. As far as distance viewing, these are average, but there are better choices.

I just got my Papilio 11 bins and they are much better than the original model. More contrast and no reflections from the external surface of the eyepiece! I called Pentax and also some stores to ask if the new 6.5x model had any improvements or was the new designation just a marketing ploy. I received conflicting information. I ordered the 11 anyway and compared the coatings on the eyepieces. The new version was greenish, suggesting multicoating. The original version had no apparent color, and reflected light back into my eyes from the eyepieces. The images in the new version were sharper and were noticeably contrastier. I recommend the Papilio 11 verson highly.
Light weight. Comfortable. Nice FOV. I won't be using my 8x42 stabilized Canons as much now. Too heavy for long term carrying. The Papilio 11 is more useful and convenient especially at closer distances.
I hope this post is helpful.

I have 6.5x21 version.
View is somewhat dim and contrast is not as good as in typical reverse porro. There are plastic elements inside (put two polarizers - one @ the front, one behind ocular and see for yourself).

Focusing wheel is delicate and very sensitive - this is an issue for birdwatching, as Papilio can refocus from touching your shirt. Not waterproof.

View is sharp (but low contrast, so bird identification can be hard) and flat (easy panning). But close focus images are stunning.

All in all - perfect for a kid/teenager/nature lover/insect watcher. For a birder it is a compromise and not a best one. But still much better than cheap small roofs or good binoculars left home Also - paired with small inexpensive 20x50 scope would be a nice first birding outfit for a beginner...
