Pentax 20X60 PCF WP II Binoculars


Nice job Pentax. Thanks.

The image is large, something important in high magnification optics. The image is crisp, resolution is high and contrast is very good. Shadow detail holds up even in deep shade and poor light. Eye cups are durable and function properly. A very well...

Heavy, for a steady-handed, after 30min you have to take a break, will be difficult to use for extended amounts of time, for some people. You will need a stable tripod.

Good quality but with a catch


I bought this binocular earlier this year with the intention to use it for astronomical observation. This is my first binocular and I spent lots of time doing research online. There were a lot of good reviews about this binoculars and much negative, so...

Good build quality, BAK-4 prisms, fully multi-coated, water-proofed

Too heavy (in my taste) and narrow field of view

Well built binocular


Bright image, good control of colour dispersion, good sharpness, but depth of field is not very good. reasonable price but provide you metal frame inside, very solid body like a tank. That is why it is heavy and big. My hand is not big enough to focus...

Bright image, very solid structure, water and fog proof

Heavy and big, but most porro types have this problems

Product Specifications

All PCF WP models offer a fully waterproof, nitrogen-filled body, outstanding optical performance with aspherical optical elements, excellent viewing comfort and a stylish body design. In addition, they are fully encased in a protective rubber housing. Because of their rugged waterproof and fog-proof design, the Pentax PCF WPs are ideal for use around and on the water, as well as for observations in harsh weather and extreme climates. The waterproof and fogproof body of PCF WP models is rated JIS Class 6 (submersible down to 1 meter depth of water), allowing them to be washed clean when they get dirty or are accidentally soaked in salt water. They have fully multi-coated optics to eliminate harmful ultraviolet rays while improving light transmission for high contrast images with no glare or flare. High quality BaK-4 prisms transmit more light at the edges to enhance illumination for easier viewing in dim light. All models incorporate aspherical optical elements to produce clear, bright images with minimal distortion. All models feature a long eye relief of 20mm or longer, making it easier for the user to see the image even when the eyes are moved away from the eyepieces. This feature is especially convenient for those who wear eyeglasses. A mechanical focus lock feature allows users to lock in at a specific distance for convenient focus-free viewing. Click-stop diopter adjustment locks in right eyepiece diopter setting. Ruggedly constructed with rubber covering to protect the optical and mechanical systems. The rubber slide-style eyecups are easily pulled out providing easier image viewing for eyeglass wearers. In addition, the eyepiece caps are designed to double-function as rain shields to make viewing easier in the rain or snow. Combine the built-in tripod socket with a tripod and the optional Tripod Adapter-N to stabilize the binoculars and prevent unwanted shake, making extended observations easy and comfortable.
