Pentax PF-80EDA Spotting Scope Review
You don’t have to do much digging to expose the truth about the Pentax PF-80ED’s reputation – it’s all legit. The quality of Pentax spotting scopes is due to two factors – world-class eyepieces and well-built objective modules. With that said, let’s get into the nooks and crannies!
We know spotters with interchangeable ocular systems require an objective module that’s up to par with high-quality eyepieces. Since Pentax already manufactures unparalleled eyepieces, they’ve successfully pulled off designing an objective module that can adequately perform efficiently with their eyepieces – the PF-80ED.
The spotter has a long focal length with 80mm ED objective lens. It’s this high-quality and large objective lens that provides the viewer with sharp resolution, snapping contrast, excellent brightness, and true color fidelity free of chromatic aberration.
On top of that, the magnesium-alloy housing with its shock-proof rubber armor is completely waterproof with a retractable sunshade and center-locking ring. Even with all its specs and techs, it still comes in lighter than other full-size spotters.
It’s the ultimate bird watching spotting scope that an avid nature observer could ask for, especially so because it comes with the included 20-60x eyepiece. But, we’ll get into eyepiece info in the Q&A.
As far as what the masses are saying, they’re impressed. What’s not to like? You’re getting the best of what’s available without having to spend Swarovski prices. Image quality is outstanding, and it certainly outperforms most of the spotters currently in the market.
- Interchangeable eyepieces
- ED glass elements
- Single focus
Pentax PF-80EDA Q&A:
The eyepiece included in this bundle is the smc PENTAX 8.5-24 mm eyepiece with a zoom range of 20-60x magnification.
It’s completely waterproof and nitrogen-purged. It also has Super-Multi-Coating optics, and it can be twisted into the scope and locked into place.
While objective lens quality is often the governing factor over resolution, contrast, color fidelity, and brightness, it’s the job of the eyepiece to magnify the image and make use of the detail transmitting through the aperture down the focal length. However, eyepieces are not easy to design or cheap to make. More often than not, it’s the eyepiece that limits a spotting scope’s performance, and most people aren’t willing to pay what it takes for a quality eyepiece suitably apt for the best objective lenses.
With that said, we have Pentax. Pentax certainly sets the current standard, or is definitely within the standard, of what quality eyepieces for bird watching or visual astronomy should be like. Without suitable field of views, acceptable eye relief, usable power, and applicable optical quality, the eyepiece won’t be able to maximize what the best objective lenses can provide. Good thing for you, you have the best of both worlds with the PF-80ED and its included zoom eyepiece!
The excellent manufacturing design of Pentax spotting scopes is the 1.25″ diameter eyepiece receptacle that’s considered the American standard. Because of this feature, it’s not only compatible with many Pentax eyepieces, but it can also be used with several other astronomical eyepieces offered by other brands. Other spotting scopes can’t brag about this feature, and many of them may offer interchangeable eyepiece technology but they offer no additional eyepieces for use. This is definitely a bonus perk for buying Pentax!
You can. Most of the time, this is the popular option because everyone has various needs to suit their spotting activities. While the price may be cheaper to purchase the angled objective module alone, you will have to spend extra to purchase an eyepiece.
Yes! The PF-80ED is the straight model, and the PF-80EDA is this angled model. The straight model has a few differences in the fact that it weighs only 49 ounces and dimensions are 15.6 (W) x 4.7 (H) x 3.8 (D) inches. It also includes caps for both the objective and eyepiece lenses and a case.
Atmospheric conditions are always going to present visual and performance issues at the range when looking for usable detail to see groupings. However, the PF-80ED is a favorite spotting scope for this exact use. Several field tests confirm that this spotter is capable of seeing groupings beyond 500 yards 100% of the time when conditions were good and ideal. When conditions are bad, visual spotting of groupings is limited to about 50% of the time for distances at 500 yards and further.
The included case is a soft Cordura-style nylon case that can be kept on the spotter during use. It has velcro fastenings with fold-back flaps to ensure this feature. As a carry bag, it’s water-shedding for when it rains, and it also has carry handles – one of which can be lengthened for use as a shoulder strap.
- Extra-low dispersion glass elements to reduce CA
- Available in both straight and angled models
- Lightweight and compact for convenience and portability
- Interchangeable eyepieces available; works with multiple Pentax eyepieces
- Fully weatherproof and fogproof with durable, shock-proof rubber armor
Our Verdict on the Pentax Spotting Scope
The scoop on the scope is, the Pentax PF-80EDA is an excellent optic if you’re in the market for a spotter. It’s right up there with the best, but it definitely doesn’t cost the same. It’s a lightweight spotter with heavy emphasis on optical quality to deliver high performance results.
But, if you want to spend less than $1000, the Pentax PF-65ED fits the bill. It even includes a 20-60x eyepiece in the mix! For both the PF-65ED and the PF-80EDA, the spotter with the included eyepiece is definitely the most economical buy.
However, the 2018 Vortex Viper HD 20-60×85 spotting scope is one optic that will have the Pentax watching its back. It’s brand new, has the upgraded Helical focus, and it sports specialized coatings galore!
Pentax combined excellent handling and balance, weatherproofness, optical quality, and world-class eyepieces into one outstanding spotting scope. It definitely weighs in lighter than its full-size competitors, and it comes in cheaper too! Is the PF-80ED a keeper? You betcha.
