High-Precision Pentax PF-65ED II 65mm Spotting Scope with SMC XW 16.5mm Eyepiece

Ricoh Pentax SMC XW 16.5mm Eyepiece for Spotting Scopes and Astronomical Telescopes (2-Inch)

The Ricoh Pentax XW 16.5mm Eyepiece is used with high-grade spotting scopes. It offers high performance and clear wide-angle. The latest addition to the successful SMC Pentax XW series, it features an 85-degree apparent angle of view and 20mm eye relief to deliver comfortable and clear viewing.

Top Quality for Stunning Images

By incorporating high-refraction, extra-low-dispersion lanthanum glass elements, the XW 16.5 produces stunning images having minimal aberrations. It compensates for the spherical aberration of the pupil to reduce the disturbing blackout effect.

Efficient Light Transmission with Pentax-Original Multi-Layer

The lens surfaces that come in contact with air are specially treated with the Pentax-original multi-layer coating, and the laminated surfaces are treated with innovative partial coating. This treatment allows efficient transmission of light (up to 90 percent, and 96 percent at 550nm) over the visible light spectrum.

Advanced Light-Shielding Technology Delivers Better Image Contrast

The XW 16.5 features a light-shielding diaphragm at the most effective position. Pentax’s advanced computer simulation technology reduces internal reflections to produce high-contrast images.

Durable and Weatherproof Construction

With a JIS Class 4 weatherproof construction, the XW 16.5 can be used under drizzle or under night dew. However, it is not designed for underwater use, and submerging it underwater should be avoided.

Sleeve Size and Design of Eyecup

This eyepiece has a sleeve size of 50.8mm (installment diameter) and if you remove the screw-on eyecup, you can find the screw thread with a 43mm diameter and a 0.75 pitch.

Versatile Pieces for Every Purpose

Alongside the XW 16.5 Eyepiece, the XW series features versatile eyepieces that can be used for star-gazing to planet observation.

Pentax PF-65ED II 65mm Spotting Scope (Straight Viewing, Eyepiece Required)

The Pentax PF-65ED II 65mm Spotting Scope is a compact, high-performance spotting scope featuring a 65mm ED lens and straight-line barrel for outstanding portability and easy subject targeting. It requires an eyepiece for proper use.

Superb Optical Performance

To optimize the PF-65EDII's optical performance, Pentax made a thorough review of the optical designs utilized in its previous spotting-scope models. It then made improvements to every optical element during the scope's development, including the incorporation of high-resolution ED (Extra-low Dispersion) optical elements in the objective lens. As a result, the PF-65EDII provides a clear, bright image field in all types of observations, and assures outstanding image quality in high-magnification digital photography using a digital camera.

Compact, Portable Design with a 65mm Objective lens

The PF-65EDII features a compact, lightweight body with a 65mm objective lens to assure outstanding portability and maneuverability in the field.

Straight-Line Barrel for Easy Targeting of the Subject

The PF-65EDII's straight-line barrel lets you spot the subject swiftly and accurately, even from a moving vehicle.

High-Resolution ED Elements

The PF-65EDII's 65mm objective lens incorporates ED (Extra-low Dispersion) glass elements to deliver a sharp, high-resolution image with minimal chromatic aberrations.

SMC Pentax XF-Series Eyepieces

The PF-65EDII accepts any of the three SMC Pentax XF-series eyepieces: two unifocal models with long eye relief, and one zoom model (all optional). By removing the screw-on-type eyecup, you can mount an eyepiece on either of the PF-65EDII's two eyepiece receptacles (one for the unifocal models with 30.5mm in diameter and 0.5mm in thread pitch, and another for the zoom model with 43mm in diameter and 0.75mm in thread pitch). In addition to XF-series eyepieces, the PF-65EDII also accepts any of the five high-performance XW-series eyepieces (four unifocal models and one zoom model) designed for astronomical observation, assuring greater flexibility in the choice of an eyepiece that best accommodates specific user requirements.
