The PF-80EDA features a large objective lens with an 80mm effective aperture to produce a bright image field for easy subject spotting and accurate focusing.

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

The PF-80ED<font class="sub">A</font>&#8217;s 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.

The PF-80EDA is made of heavy-duty magnesium alloy to reduce weight and protect inner mechanisms, while its protective rubber housing further enhances shock resistance and durability.

The PF-80EDA incorporates a dust-shielding glass element in its eyepiece receptacle to assure JIS Class 6 waterproof construction, so it can be used in the rain with no worries.

The PF-80EDA’s body is filled with nitrogen gas to prevent internal fogging caused by sudden temperature changes, providing a clear vision under any condition.
