Pentax A-Series AD 9x28mm Roof Prism WP Binoculars Review

Let’s Dive into Pentax A-Series AD 9x28mm Roof Prism WP Binoculars

The Pentax A-Series AD 9x28mm Roof Prism WP Binoculars offer a compelling blend of optical quality and compact design. Manufactured by Pentax, these binoculars promise full-sized performance in a package that’s easy to carry, boasting multi-coated lenses and a waterproof construction. As someone who spends a significant amount of time outdoors, from scouting hunting locations to birdwatching on early morning hikes, I was particularly interested in their potential as a versatile and reliable optic.

I was seeking a pair of binoculars that were powerful enough for detailed observation, yet small and light enough to carry comfortably on long treks. Many binoculars offer either exceptional clarity at the expense of bulk, or a lightweight design that sacrifices image quality. The Pentax A-Series AD 9x28mm Roof Prism WP Binoculars seemed to strike a promising balance.

Upon unboxing, I was immediately impressed by the solid feel of the Pentax binoculars, despite their relatively light weight. The green, fiber-reinforced polycarbonate chassis feels robust and provides a secure grip. The size is noticeably more compact than my older 10×42 binoculars, and they feel much more manageable.

Compared to my previous Bushnell Legend Ultra HD 10×42 binoculars, the Pentax binoculars are smaller and lighter. Also, compared to a friend’s Vortex Diamondback 8×42, the Pentax offer a higher magnification in a smaller package. I chose the Pentax because of its advertised combination of magnification, portability, and weather resistance, features critical for my outdoor pursuits.

My initial impression was one of cautious optimism. The size and weight were exactly what I was hoping for, and the build quality appeared to be excellent. I was eager to see how they would perform in the field, where their optical capabilities would truly be tested.

Real-World Testing: Putting Pentax A-Series AD 9x28mm Roof Prism WP Binoculars to the Test

First Use Experience

My first real-world test of the Pentax A-Series AD 9x28mm Roof Prism WP Binoculars was on a scouting trip for deer season in the Allegheny National Forest. The terrain was varied, with dense forests, open meadows, and steep hillsides. The weather was typical for late autumn: cool, damp, and with a persistent drizzle.

The binoculars performed admirably in the less-than-ideal conditions. The fully multi-coated lenses provided a bright and clear image, even in the dim light of the forest understory. The waterproof design proved its worth as the rain steadily fell, and I didn’t have to worry about damaging the optics.

I found the center focus knob easy to operate, even with gloves on, and the twist-up eyecups were comfortable and effective, providing a good eye relief distance. It took only a few minutes to adjust the diopter and achieve a sharp, clear image. The close focus distance of 9.8 feet also allowed me to observe smaller details in the immediate surroundings.

Extended Use & Reliability

After several months of use, the Pentax A-Series AD 9x28mm Roof Prism WP Binoculars have proven to be a reliable and durable companion. They have accompanied me on numerous hiking trips, birdwatching expeditions, and even a few fishing outings. The binoculars have been exposed to a variety of weather conditions, including rain, snow, and extreme temperatures.

Despite the rough handling, the binoculars show minimal signs of wear and tear. The polycarbonate chassis has proven to be remarkably resistant to scratches and impacts. The lens coatings have held up well, showing no signs of degradation.

Maintaining the binoculars has been simple. A quick wipe down with a microfiber cloth after each use is usually sufficient to keep the lenses clean. I’ve occasionally used a lens cleaning solution to remove stubborn smudges. Compared to my older binoculars, the Pentax binoculars require significantly less maintenance.
