Overview
Large 80mm Objective Lens for a Bright Image Field
Features a large objective lens with an 80mm effective aperture to produce a bright image field for easy subject spotting and accurate focusing.
High-Resolution ED Elements for a Sharp, Crisp Image
The objective lens incorporates ED (Extra-low Dispersion) glass elements to deliver a sharp, high-resolution image with minimal chromatic aberrations.
PF80EDA Slanted Barrel for Comfortable Viewing
The PF-80EDA lens barrel is slanted 45 degrees upwards toward the eyepiece to assure the most comfortable viewing position, even when the subject is at the top of a tree or on a steep hill.
Lightweight Magnesium-Alloy Body for Portability and Shock Resistance
Made of heavy-duty magnesium alloy to reduce weight and protect inner mechanisms, while its protective rubber housing further enhances shock resistance and durabilit.
Waterproof Construction for All-Weather Viewing
Incorporates a dust-shielding glass element in its eyepiece receptacle to assure JIS Class 6 waterproof construction, assuring worry-free viewing in the rain.
Nitrogen-Filled Body to Prevent Fogging
The PF-80ED’s body is filled with nitrogen gas to prevent internal fogging caused by sudden temperature changes, providing a clear vision under any condition.
Other User-Friendly Features
- Sight line on top of the lens barrel for easy targeting of the subject
- Built-in lens hood to shield out excessive light and protect the objective lens surface
- Tripod receptacle with click-stop rotation mechanism for easy twisting of the lens barrel to position the eyepiece at the most comfortable angle without changing the direction of the lens barrel (PF-80EDA)
- Optional camera adapter (PF-CA35) to convert the PF-80EDA and or PF-80ED into a 1000mm super-telephoto lens for 35mm-format SLR cameras, and 1530mm super-telephoto lens for digital SLR cameras.
