Housed in a lightweight magnesium-alloy body, the PF-100ED spotting scope features the time-proven porro-prism optics and an extra-large 100mm objective lens incorporating ED (Extra-low Dispersion) glass elements to produce a sharp, clear image with minimal chromatic aberration. Its straight-line optical barrel design makes it easy for you to locate the subject. The scope barrel has an American-standard 31.7mm-diameter eyepiece receptacle, which accepts one of six optional eyepieces of different magnifications to satisfy many different viewing requirements. This receptacle also has a dust-shielding glass to make the scope barrel airtight and waterproof (rated JIS Class 6).* Coupled with a nitrogen-injected barrel, this unique mechanism prevents the internal fogging caused by sudden temperature changes.

Because of its superb image quality, interchangeable eyepieces and airtight body construction, the Pentax PF-100ED Spotting Scope can be used for a wide range of subjects and performs flawlessly even under demanding conditions in the field.

Built-in lens hood to cut excessive light and keep the objective lens free of dust and rain

Effortless focusing operation using an easily accessible focusing knob

Built-in tripod socket with click-stop rotation mechanism

Long 20mm eye relief for easy viewing — especially for those wearing eyeglasses

Rubber housing for protection against shock and damage

Pentax offers six optional interchangeable eyepieces for the PF-100ED Spotting Scope to meet individual requirements: five fixed-focus XL-type models with magnifications of 22.5, 30, 45, 60 and 90 times, and one zoom model offering a magnification range of 26 to 78 times. All these eyepieces are commonly used for astronomical telescopes and renowned for their outstanding image reproduction.

Pentax also offers the PF-CA35 Camera Adapter, which converts the PF-100ED into a 1250mm F12.5 super-telephoto lens for use with Pentax K-mount 35mm SLR cameras.
