The PF-65ED II Spotting Scopes are somewhat a recent release from Pentax. They modified their old 65-mm scope line with better-quality glass material and multi-coated lens.

Spotting Scopes is a type of mini telescope designed for outdoor enthusiasts for terrestrial viewing. They can be used for hunting, birding, surveillance and so forth. With the 20-60x XF zoom eyepiece, the straight version comes at an affordable price range below $1,000 while there is ED glass material with other attractive fixtures like this one for well over the same range.

Our Remarks

Summing up, the Pentax Spotting Scopes with excellent Eyepiece images has been proved suitable for terrestrial or lunar viewing because it can provide perfectly sharp, bright, contrast ratio and true color, so the recommendation for you is this product. Even if you are a keen birder or a nonprofessional stargazer occasionally use it to gaze at the Moon, this device will meet your expectations. From this point of view, the price/quality balance is more than acceptable. There is also the Diamondback 20-60x60mm Spotting Scope by Vortex Optics at almost same qualities. But, the PF-65ED Pentax Scopes come at a low price which makes it affordable and a simple and intuitive option thanks to the rational design.


Question : Does this PF-65ED II have Dual Focus?
Answer :Unfortunately, the Pentax Spotting Scope has a single focus mechanism. But this is nothing really bad though most people prefer dual focus on spotting long-range. An optics with such quality, Pentax proves how well this feature can function over two knobs. They retain quality where it has to be as well as where they can deliver it smoothly.

Question : What are the differences between the PF 65 ED-II & the EDA-II?
Answer :There are only a few differences between these two models. The angled version has a rotating feature which you can twist on for your convenient observation. The carrying case is specified with the straight versions which Pentax did not specify with the angled model. It is well-suited to use on the straight model as you use it.
