Olympus Optical Co., Ltd. is pleased to introduce the 7-15x 25 ZOOM PC and 10-30x 25 ZOOM PC porro-prism binoculars. Offering superior cost performance, the new ZOOM PC Series models combine advanced functions with a compact, lightweight design. The 7-15x 25 has a zooming range of 7-15x, while the 10-30x 25 has a 10-30x zoom lens for a wide range of needs.
To minimize chromatic aberration-a common problem at increased magnifications-the high-performance optical system has a lens element made of Extraordinary Dispersion (ED) glass. The eyepiece optical system features an anti-UV lens element to cut harmful ultraviolet rays and minimize fatigue during extended use.

Both models are ideal for sightseeing and outdoor pursuits such as camping and spectator sports. The grip has a special rubber coating that prevents slipping and makes handling more comfortable. The metallic-silver finish also contributes to the binoculars' combination of contemporary good looks and classic style.
Main Features
High-Performance Zoom Lens
Both new ZOOM PC Series models have a high-performance optical system with a lens element made of Extraordinary Dispersion (ED) glass to minimize the chromatic aberration that often occurs at increased magnifications. The ZOOM PC 7-15x 25 has a zooming range of 7-15x, while the 10-30x 25 features broader coverage of 10-30x. With this versatility, it takes only a touch of the Zooming Lever to take in an entire scene at a low magnification and then move in for a close-up at a higher setting.
UV Protection
The eyepiece has a specially formulated lens element with anti-UV protection that cuts harmful ultraviolet rays. Designed to minimize eye strain during extended use, the PC Series is ideal for sightseeing, camping and other outdoor pursuits.
Sophisticated Design
The grip has a special non-slip rubber coating that makes handling firm and simple. Suited to all tastes, the design also features sleek lines and a metallic-silver finish.
