Pentax PF-65ED II Overview

With the smallest objective lens in the series, the Pentax PF-65EDAII 65mm Spotting Scope is the ideal companion for hunters, shooters, birders, and nature enthusiasts of every stripe, delivering bright and sharp high-contrast images with true-to-life color and crisp clarity while being light and compact enough to easily carry deep into the backcountry.

Image quality is enhanced through the use of extra-low dispersion rare earth lanthanum crown glass lens elements, in a 5-element/3-group configuration, with the proprietary SMC (Super-Multi-Coating) multi-layer coatings and BAK4 Porro prisms. These optical features work together to minimize aberrations while maximizing light transmission, increasing color fidelity and contrast, and improving clarity and resolution. The 65mm objective balances performance with portability, retaining excellent light-gathering capability to keep views bright and clear without making the scope overly long or heavy so it can be carried into the field with relative ease. This model is offered without an eyepiece, but a 1.25" collet-style press-fit holder accepts standard telescope eyepieces—which offer a dizzying array of magnification options from fixed to zoom—and holds them firmly and securely in place with a centered optical alignment.

Optimized for your viewing comfort, the eyepiece holder is set at a 45° angle to the body and the tripod mount collar allows the body to rotate. Taken together, these two features enable you to precisely place the eyepiece in a comfortable position that requires the least amount of head movement during use whether you are standing, sitting, or lying prone. The spotter's nitrogen-filled magnesium housing is water and fogproof, making it able to handle extreme weather conditions and sharply changing temperatures without affecting its performance. The armored body absorbs light shocks in addition to providing a secure grip when conditions get wet or while wearing gloves. An objective lens shade is built into the front bell, which can further enhance image contrast and clarity by blocking light from causing glare and lens flare

I purchased another spotting scope that was cheaper and had a larger aperture. But the image quality was significantly degraded by CA (chromatic aberration - violet to red outline around objects) and softness. And the scope had a mechanical issue right out of the box. I searched and researched and decided I would need to spend a bit more money to get close to the quality I wanted. That meant, for me, moving from 80mm down to 65mm in aperture. The reduction in size was more than made up for by the quality of the image. The Pentax has delivered a sharp image almost free of CA. It is lightweight (my birding is often accompanied by a significant hike) and sits easily on my carbon fiber tripod - which I already owned. Currently I am using a Baader Hyperion 17mm eyepiece - which I use in astronomy. It is a wonderful match. The focuser was a bit stiff at first, but has gotten smoother with use. The smaller size of the scope body and reduced weight has proven to be a benefit. I am 68 years old and am already carrying a camera, fairly large lens, and a pair of binoculars. The scope is a great addition to the toolbox for scouting and identifying birds that are on the other side of a farm field, a pond, or a "fluddle". I do recommend-just know the eyepiece is a significant part of the visual train as is a good steady tripod and mount.

I had this spotting scope many years ago and later regretted letting it go, so I repurchased it recently, and was not disappointed to see it was as good as I remembered. I already had a nice 8-24mm zoom lens for it and it makes a great compact, travel scope. Optically, it's a very good performer (as an Astronomer, I had to turn it onto Epsilon Lyra which showed the tight components split quite reasonably with a Nagler 2-4mm zoom lens). I took this and a light-weight tripod to the top of Enchanted Rock where I got fantastic views of the Hill Country. Not all 1.25 eyepieces are necessarily going to come to focus with this scope - my 8-24mm Hyperion Zoom only just barely focusses to infinity, so a bit more in-focus travel would be desirable, but that's a small quip.

Will the TeleVue 40mm Plossl eyepiece focus ...

Will the TeleVue 40mm Plossl eyepiece focus properly with this spotting scope?
Asked by: Robert J.
I posted this question and I can definitely answer it myself. I purchased this spotting scope and the 1.25" 40mm Plossl focuses fine to infinity, at least as far as the moon. It also focuses fine at close distances albeit not as close as with my Tele Vue Oracle 3 telescope (76mm 560mm fl f7.4), but close enough for my satisfaction. This lens provides a 10x 4.3 deg. view with a 6.7mm exit pupil. A very nice bright and wide field of view.

I wear glasses. Can you tell me If the eye relief is good on this scope. Also what eyepieces would you recommend if this is my first scope and I am using it for birding?
Asked by: Linda
Yes this scope would be good for someone that wears Glasses, and needs good Eye Relief. The Pentax XF smc 6.5-19.5mm Zoom Eyepiece (1.25") would be a good choice for Birding. Link to Eyepiece: https://bhpho.to/2JaipuN

question

Where is this scope made?
Asked by: Anonymous
I purchased this scope in August of 2019 and it is still marked as made in Japan. A very small sticker on the bottom of the mounting shoe states this. My old eyes required reading glasses to see the tiny print.

question

What maximal increase can be attained on this good on condition of maintenance of quality image ? What eyepieces will suit for this purpose ?
Asked by: Anonymous
The image magnification can be dtermined by dividing the focal length of the scope (390mm) by the focal length of the eyepiece. This scope will accept 1.25 astronimical eyepieces and the best ones suited for this scope are generally theose with a wide field of view. The greatest magnification I have achieved with this scope has been 87x using a 4.5mm Baader Hyperion with a claimed 76 degree field of view and when conditions are optimal, this scope will provide an excellent image. I have even used it to view astronomical objects such as Saturn and Jupiter mounted on a Sirui T1005x travel tripod and Sirui K20x ball head and have been impressed by the results.

question

working temperatures ?
Asked by: Anonymous
Have only used it in mild temps. However, believe it or not, compared it side by side with $1,000 60 Takahashi using both Pentax zoom and 4 Televue radian on both scopes and Pentax was sharper at infinity.
