Pentax UP 8-16x21 Green Binoculars (Green)

These binoculars work well. The lenses are nice and crisp. Really easy to operate zoom and focus. Adjustable eye cups a nice touch.

Poco mas grandes que la palma de mi mano, si lo oculto bajo mi brazo no hay quien los vea, ligeros y una excelente optica, Si vas a hacer trekking varios días estos son los que se nececitan, no ocupan espacio ni significan peso notable en tu mochila

Took the binoculars up to Aberdeen and used them to watch for dolphins and visit the seal colonies they worked well and were easy to use and adjust worked well in low level light . However what was disgraceful of Amazon was they were delivered in a paper bag with no protection so the box containing they binoculars was crush damaged, fortunately the binoculars because they were in a good leather case were undamaged - I Will think twice about buying any fragile from Amazon again

These definitely feel like a very substantial, well built set of binoculars as you hold them in the hand. The dials are precise and very easy to operate. They are very well balanced and easy to steady. A high quality build.Also, the zoom dial is in a more appropriate and ergonomic location as compared to other brands. You don't have to lose your view while fumbling with zoom on these. It's right up on top and falls naturally under the fingers right behind the focus wheel and has a short and smooth sweep to it. Other manufacturers put the zoom down under, usually on the right side where it is very awkward to control without adjusting your grip and creating a viewing disadvantage.The diopter adjustment is right behind the zoom and pops out with a push. Once adjusted, just pop it in where it's out of the way and forget about it. It's a very nice feature. All dials are lined up with easy access. Kudos to the engineers!Despite the 21mm objective, the zoom on these allow more light transmission than other zoom binoculars with larger objective lenses that I've owned over the years. Mostly TASCO and Bushnell.Just for image comparison, I focused these, a pair of fixed power Nikon Aculon T01 8x21mm, and a pair of TASCO 8-24x25mm on my 75" HD TV in a dark room from approximately 15" away. The image from these was definitely brighter and more true to color than the Nikon's and totally blew away the TASCO. The TASCO is going back. What rubbish!Another very nice feature is actually the strap which has a unique quick release system that consists of metal pins that attach with a push, slide and click. Just push the release button, slide the strap end forward and lift to release. This is a much better system than those cheap plastic snap connectors with a cord loop on other brands. When the strap is removed, there are no pigtails dangling about. It's a durable, convenient and clean design.Overall, I would say that Ricoh/Pentax has employed engineers/designers that are actually educated to a high degree and institute a high level of common sense in thier designs. The design of this binocular is very well thought out. One of, if not the best I've seen.As far as the aesthetics go, I think they look absolutely up to date, if not a bit futuristic. These are binoculars that would look right at home in James Bond's arsenal of gadgetry. No fancy rangefinder or laser guidance system, but they definitely have the look. LolMy intended use for these is in dry conditions, so being waterproof is not a priority, but would nonetheless be a nice bonus feature. Oh well. What idiot submerges binoculars anyway? The strap is not only for carrying, it's a safety strap too! Use the strap. Don't drop them in a lake, stream, puddle, bathtub, sink or toilet! Don't put them in the washing machine or dishwasher either! I could go on and on...As far as rain goes, I don't think it will be an issue unless you're in a monsoon, hurricane or similar. In those conditions, you should be running for cover, not looking through your binoculars.In conclusion, Money well spent. I'm very pleased with this purchase and will definitely look to RICOH/PENTAX in the future for my optical needs.

Typically Budget Zoom Binocular Pairs Specially Smaller one gives dull and less focus Images.But Pentax 61963 8-16X21 Zoom Porro Prism Binocular give sharp and bright images which are way better than most of 50mm Zoom Binoculars.Don't buy any Zoom Binocular Pair which cost say less than $750 without testing the Pair by yourself.The reason for that is majority of Zoom Binoculars up to mid range fail to give sharp and bright images.Same apply to Zoom monoculars too.Gerber (German) and Bushnell mid range Binoculars maintain quality.May be Berber is the best quality and price Binoculars out there, I own both brands.Gerber 16x50 Water Proof Binocular pair is so cheap but it's quality is even better than Bushnell.Good Luck
