Pentax is very well known company that has been on the market for many years. The produce high quality optics that make your life more interesting.

Pentax has been in the business for over 75 years. The name of the company itself is not Pentax.

It’s known as RICOH IMAGING Company Limited that was founded in 1919. AT first it was known as Asahi Optical Joint Stock Co.,

Later they changed name to RICOH IMAGING Company Limited and still it is operating under this name.

When they produced their first SLR camera in the 1950s they launched it under the PENTAX name and still they keep this brand name for all their optic devices.

RICOH IMAGING Company produces PENTAX DSLR cameras, sport optics equipment, digital cameras, compact cameras, lenses, accessories, such as batteries, bags, flashes, adapters, chargers, memory cards, tripods, hight quality binoculars.

Our main topic today is about binoculars, PENTAX binoculars. RICOH IMAGING offers various types of binoculars, medium and high class binoculars.

Almost all models are waterproof, forproof and made from magnesium alloy which makes Pentax binoculars lightweight and durable.

All lenses are fully multi coated and thanks to it image produced by binoculars is crystal clear and bright.

The company even offers ED Glass binoculars known as extra low dispersion optics.

ED glass optics have almost zero chromatic aberration which means image produced in such binoculars is not only crystal clear but colors are maximum true without any distortions.

All Pentax binoculars are of great quality, have an excellent design and produce high quality image.

Most Pentax models are made of magnesium alloy which makes them lightweight and easy to use.

Even Pentax SP 20×60 is relatively light compared to other high power binoculars from Oberwerk, Celestron or Gosky.

Those binoculars have objective lenses 80 mm which makes them heavy and not usable without a tripod. Pentax can be used without a tripod too.

Most Pentax models are waterproof and fogproof which makes them usable for hunters and travellers.

I have Pentax SP 20 x 60 WP Binoculars and I’m satisfied with the quality. Especially I like its lock feature on the central focus wheel.

It comes with neck strap, carrying case with strap and limited lifetime warranty.

In power binoculars such as this one field of view is a little narrower but the image is clear and sharp.

Though some people may not like Pentax brand I disagree with them.

You can even find people that don’t like Zeiss binoculars though Zeiss produces one of the best optics in the world.

You will always find critics. My opinion about Pentax is that it’s a great choice in terms of quality, durability and relatively reasonable price.

Anyone who has an expertise in the field of optics know that Pentax is a premium brand that can easily compete with Nikon, Vortex, Carson, Leupold and many other well known brands.

Pentax binoculars are not cheap but remember that they are premium quality binoculars and highly durable as well as produce high quality image.

Most of them have Phase-Corrected BAK4 Roof Prisms with Fully Multicoated Optics.

Thanks to it image produced by Pentax optics is always crystal clear and sharp. They can be used in all weather conditions.

Pentax comes in multiple configurations and price range that can easily meet requirements and the budget of all groups of people.

Almost all Pentax binoculars are made of magnesium and have rubber coating that makes them highly durable.

Pentax binoculars are all long eye relief optical devices that can be used for long viewing sessions including eyeglass wearers.

    The humble binocular has certainly evolved over the last few years and reading this review and looking at my pair of binoculars makes them look rather ancient.

    I use binoculars mainly for when you don’t get a good seat at the theatre so that you can look closely at the actor’s faces. Which binocular set would you recommend for this purpose out of your recommendations here? The Pentax range certainly does look impressive and I wouldn’t mind upgrading my old pair with one of these.

    • Adam says:

      I think for theatre you better choose binoculars from other brands. Pentax binoculars start from magnification 8x which is too powerful in my opinion. For sporting events it’s ok, but not for theatre. For this purpose you better choose magnification 3x or 4x.

      Especially I recommend:

      Bushnell Spectator 4x30mm Extra-Wide Compact Binoculars
      Orion 4×21 Super-Wide Angle Binoculars

      These two have unbelievably wide field of view up to 17 degrees. It’s simply fantastic.

  2. Sherrane says:

    Just wondered why Pentax and not another name brand? I have use for binoculars on certain occasions, but I cannot always get a good field of view and you have explained that. Which set can you recommend for me? I need one with a wide field of view for sporting events and general use.

    • Adam says:

      Hi Sherrane. Of course, there are many other brands out there. Pentax is just one of many others. This is my review of Pentax binoculars and I recommend many other brands too. If you need a pair with a wide field of view look at these two binoculars:

      Bushnell Spectator 4x30mm Extra-Wide Compact Binoculars
      Orion 4×21 Super-Wide Angle Binoculars

      Here is the link.

      For sporting events and general use I would recommend magnification 8. It’s an ideal choice because they are powerful and have field of view around 7-8 degrees.

    We have a binocular at home and after using it for like 7-10 minutes, I always feel dizzy. Is it the lens? My husband is an outdoor type of  person that’s why he has these kinds of things. And what are the different types of prism you mentioned in the specs of each binoculars? What is its use? 

    • Adam says:

      Most likely it is lens issue if your binoculars is non brand. Very often non branded use cheap optics that can harm your eyesight. If you have branded binocular then maybe it’s your eye problem. Binoculars with BK-7 prism can cause eye strain. I always recommend choose BAK-4 prism which is widely used by all manufacturers of optics. For more details about types of prisms used in binoculars read my article here. For more questions read my binoculars FAQ.

  4. DrJ says:

    My Celestron 12 x 70 binoculars are very sharp (surprisingly so!) but they became out of collimation. I’ve adjusted the screw on each barrel but cannot fix them. I’m considering the Pentaz 12 x 50 binoculars for casual stargazing and occasional spotting 25 yd .22LR targets. Is the newer #65873 noticeably sharper than the #65904? I’m also considering the Pentax 16 x 50 but I fear that the exit pupil will be too small. (If the 16 x 60 were still available, I would strongly consider it). Thank you. DrJ

    • Adam says:

      Sorry to hear about the issue with Celestron. For spotting I would recommend 8x or 10x binoculars. For me field of view is important. Pentax image quality is always good at the sacrifice of narrower field of view. 16x magnification is the best powerful binocular to use from hand. If you are looking for a powerful binocular for stargazing I believe 16x or even 20x binocular is not enough. You better choose 25x binocular, such as:

      Orion GiantView 25×100 Astronomy Binoculars
      Oberwerk 25×100 IF Deluxe Binocular
      Celestron SkyMaster 25X100 ASTRO Binoculars
