Designed for the nature enthusiast who wants to pack light without sacrificing image quality, the Pentax 8x25 A-Series AD WP Compact Binoculars deliver bright, clear images while weighing in at just 10.6 ounces. Their BAK4 roof prisms are phase corrected to improve image contrast and enhance color rendition. All of the optics are anti-reflection and fully multi-coated to maximize light transmission, producing the brightest views possible.

An asymmetrical hinge design enables the binoculars to be folded up much smaller than typical center-hinged optics. In order to cut weight, the housing is made of corrosion- and impact-resistant fiberglass-reinforced polycarbonate polymer. The material is also temperature resistant, allowing for their use in extreme climates while reducing expansion and contraction that wide temperature swings can cause (and which can make the optical components move out of collimation over time). Their optical tubes are nitrogen filled and O-ring sealed, making them submersible to 3.3' as well as fogproof in all weather conditions.

  • 8x magnification
  • 25mm objective lenses
  • BAK4 roof prisms
  • Phase-corrected prism coatings enhance contrast and improve color rendition

Very portable, very nice!

I was tired of lugging my moderately-sized binocs that wouldn't fit in a pocket. These are perfect. Great optics, smooth operation, and very nice eye relief.

portable and excellent quality

bought for canoe trips, to watch birds, search for portages and campsites, and more. these are waterproof and rugged, yet small enough to fit in a pocket. and yet- the visual quality is excellent and sharp. very happy i made this purchase.

Excellent image, decent ergos

The glass and image quality is excellent. When hung from the neck strap, they don’t lay flat against the body, because of the way their weight is distributed. And it’s a tight squeeze to get them back in the case. But those are pretty minor issues. I would definitely buy these again.

Astonishingly good for the price

I own several pairs of highly rated binoculars that I use for bird watching, but I wanted something really small and inexpensive to carry with me during other activities. I do own a pair of pocket binoculars that are even smaller than these, and cost much more, but they are 10X power, which makes them hard to hold steady, and their eye relief is barely adequate for someone who wears glasses, as I do. I have found most binoculars costing less than $200 to be terrible, but I've had had good luck with Pentax cameras and optics and on paper these were exactly what I was looking for, so I bought these. All I can say is that these are astonishingly good for the price. The image is bright and free of distortion and chromatic aberration right to the edge of the field of view, which is admittedly much narrower than larger binoculars. Ricoh's specs do not indicate that these use ED glass, but the optical quality is such that I would have guessed they do. They are also solidly built and focusing is tight and precise. There are no objective lens covers and the flimsy ocular lens caps provided are worthless, but that's fine for something I want to keep in a lightweight case in my pocket or a bag. As other reviewers have noted, the case supplied is too snug, but a Megagear neoprene case for small cameras like a Canon Powershot or Fuji XF10 fits perfectly.

Quite good for the size and price

Small binoculars have limitations, but these are above average, are well-suited for casual use when size and weight are a concern. The eye-relief is unusually good for inexpensive binocs, and the inter-pupillary distance is good for small folding ones (the specs don't list, but it's enough for me, and I have a wide IP.) These will find a place in my travel kit, and will serve as opera glasses, but they won't replace my larger binoculars for more serious use.

Bright, sharp, and excellent magnification

These deliver an excellent view - bright, crisp and clear. They are lightweight, a good size to fit the eyes comfortably and to use the controls. The controls are simple to use and intuitively placed. Excellent Pentax optics.

Very impressive

These were smaller than I anticipated, but I’m not complaining since they work better than I expected. It seems realistic to be able to pocket these in a jacket. Optical quality is excellent given the size. Compared to the binoculars of yesteryear the fact that this level of quality is this cheap is really remarkable. They work with my glasses although that naturally cuts down the FOV.

What is the inter-pupillary distance for these binoculars? This is a critical spec and it is missing from the displayed specs.
Asked by: William
Bear in mind that this just eyeballing it (so, error roughly +/- 1mm). I estimate the adjustment range to be 34mm to 75mm. If your eyes are set far apart, the folding style binocular are probably not going to work for you regardless of the specific model.

Would these be good for a person with a small face?
Asked by: Anonymous
Yes this model would be good for a small face. They fold up very small, so they will be able to adjust to the eyes well.
