Product Highlights
  • Compact BAK4 Porro Prisms
  • Rubber Armoring
  • Center Focus
  • Rugged Dual-Axis Body Design
  • Super Multicoated Lenses

The 8x21 UCF R binocular from Pentax features a clever dual-axis body design. Unlike common dual-hinge optic, the UCF R's eyepieces move simultaneously when adjusting them for viewing. This type of construction makes setting the binocular up a breeze, and it adds a significant amount of strength and stability to the entire optic.

Sporting a rubber-covered housing and sliding eye cups, the UCF R provides a secure grip and a customized view. The optical system consists of a pair of BAK4 roof prisms in a compact configuration, and super multicoated lenses for optimum viewing at all times. The 8x21 UCF R has an entry-level price-point, yet it's durable, easy to carry and use, and it delivers excellent viewing performance.

BaK4 porro prisms: crisp clear viewing, accurate colors,
Sliding eyecups for a customized fit, rubber armoring for a secure grip
Sleek contemporary dual-axis housing design is compact, rugged, easy to handle

    First of all let me say that I am very picky consumer and easily get disappointed if product is not perfect. After reading this sentence look at the rating I gave this product... correct, 5 stars. It all started with hockey game I was going to attend and I needed a compact binocular that will fit into my pocket, won't be heavy, will be easy and fun to use. My first purchase was compact binocular of one of other brands and at first look it was okay, but when I went to the game I was extremely disappointed, everything was darkened as if I was wearing sunglasses, also some weird haze was around the lights, I had to return it. Then I bought another compact from other popular brand, and was disappointed again, same problem, not as severe as with first purchase, but yet again I did not like it and had to return it again, third time I went to other manufacturer and purchased another compact again, guess what?, disappointment again, this time one of the lenses was defected, it had small bump on it so when you look through binocular you would see large dark spot in the middle, I thought it's just a dirt that stuck on the lens, but no, it was actual glass that sort of melted and bubbled up, I do not even understand how that is possible, isn't manufacturer suppose to polish all lens and would have seen that defect as quality control stage, it was right there in the middle of outer lens? Anyways, after being disappointed three times in one week I decided that I will make last call, I would purchase this one, and if it at-least okay, I will just keep it. But, when this thing arrived I was surprised right away, it turned out to be even smaller then other three binoculars, definitely has better design and finish, and overall feels just right. So I went to park to check it in action, turtles, birds, squirrels, distant vegetation, it all was visible very clear and sharp and was very easy and quick to focus. I was very happy that day, later on, I went to another hockey game and this little binocular did it's job flawlessly, easy to focus, very clear, no darkening effect at all great sharpness. You won't go wrong by buying this product and will be very happy.

    We bought two pairs and immediately flew to Berlin for two weeks of museum-hopping and concerts. We saw several operas and the binocular were easy to use and very good. They even worked well at the Lady Gaga concert! The only problem is that the lens holders (not the lens caps) were loose and came off one set. We had to look everywhere for them one night. Unfortunately, we didn't get back to New York for two weeks so we weren't able to take the one pair back to B and H, since they will only take stuff back for ten days. Bummer.

    Great binoculars at a great price

    Comments about Pentax 8x21 UCF R Binocular:

    I have 2 other 8x21 binoculars and the new Pentax binoculars are much better. These binoculars can't be beat for the price and are excellent enough that I have no desire to even look for a better pair of binoculars.

      Comments about Pentax 8x21 UCF R Binocular:

      I use it during hikes to the mountain. I have spotted slithering rattlesnakes with ease to make sure I avoid them. There are these birds always fighting in the sky just above my house and I finally got to see them up close. At night, the moon is also a fun thing to watch with the binoculars. The wife uses them to spot fruit in our garden. And I can't wait to take them to my next Golf tournament.

      The Pentax 8x21 UCF R binoculars are very light, just the right size to carry around, and using them is a no brainer, two controls and one of them you won't mess around with much, the other is for focusing quickly and it's done so with ease and precision. The manufacturing quality is top'o the line. The aberration of image is so low it's basically imperceptible. Then again, if you're gonna be a stickler about that, well you probably are a stickler about everything.

      I don't know if it's waterproof, I can't remember at the moment but they are binoculars. Why would you want to treat them any less carefully than you would a camera? Get them, you won't be disappointed. They come with a little pouch and a string so you can hang them around your neck. The pouch is nice but if you're like me you won't use it much. I mean, you want to zoom onto life every day don't you?

        Comments about Pentax 8x21 UCF R Binocular:

        I was looking for the binocular for watching musical performance from the most behind seat in the theater that capacity is 2,500. My previous binocular have x10 magnification lens and sometimes I had a problem of shaking view with it. And this previous one was a bit heavy and I could not hold it for a long time. So, I wanted binocular with x7 or x8 magnification lens, and is lightweight.

        This Pentax 8x21 UCF R fit to my desire. Even with one-handed holding, I did not have shaking view problem. x8 magnification is very suitable for the theater I go. Image through this binocular is very clear even in peripheral.

        Before buying, I was wondering is 8x21 good enough for my purpose or better to buy the one that have 8x25. However, the image Pentax 8x21 UCF R provide is very clear, bright, and I am very satisfied with it now.

        To be honest, the shape of this binocular did not fancy me before buying, though, I like this product very much now and I want to use it for a long time.

              Like a camera, you may lose a great opportunity because your device was too heavy or cumbersome to carry. These lightweight, yet solid binoculars are easy to pack and carry for all those times you need them. Just wish there were an easy way to get images onto phone camera.

                      I'm leaving for Africa soon and will take a lot of camera gear. I didn't want to weigh myself down with a heavy binocular but wanted to have a decent one for the trip. Read the favorable reviews and took a chance on the Pentax. I'm not a binocular expert, but I'm very satisfied with the feel, the quality, the ease of use, and the light weight. I'm very happy with my choice.

                          It's compact and practical binocular, and my wife loves it. She uses it during archery for targets. It's a Pentax.

                            I bought these as opera glasses for my girlfriend, who's an opera fan, and she reports good things about them. We haven't tried them at serious outdoor ranges but for short distances you get a very clear image --- and it can almost overcome my serious esophoria if I don't wear glasses.

                              I bought these Pentax because I wanted an inexpensive and compact set of binoculars for traveling and sporting events. They greatly outperform other compacts I've tried, and are almost as good as my $200 8x42 Nikons! I haven't taken them to a game yet, but I just did a road trip up Highway 1/US 101 and used them quit a bit. They adjust very smoothly too, which is great for trading back and forth with my wife.

                                This are great inexpensive binocuolars. The optics are very bright and amazingly sharp. They are very lightweight. Focusing wheel is smooth.

                                What I did not like is that rubber eye cups are quite loose and fall off easily.
