Summary
Olympus Optical Co., Ltd. is pleased to announce the introduction of the 10x 25 RCII R roof-prism binoculars. Compact, lightweight and weatherproof, they are suited to a full range of outdoor pursuits. They also feature an anti-UV lens element that protects the eyes from ultraviolet rays.
For The Active Life
Both the new RCII R roof-prism models combine affordable pricing with a small, lightweight design and weatherproofing. 

The eyepiece's optical system offers the protection of an anti-UV lens element that cuts harmful ultraviolet rays. It also helps to minimize eyestrain during extended use. The long eye relief and eyepiece ring adjustment maintain a wide field of view even when a person is wearing glasses or sunglasses. 

To make the binoculars easy to take along, the body can be folded to make them even more compact. Handling is also improved by the special rubber coating on the sophisticated black body. 

With their convenience and durability, the  10x 25 RCII R models are ideal for every venue from beaches to ski slopes. Suited to today's active lifestyles, their design and performance promise to make travel, bird-watching and spectator sports more rewarding and enjoyable.
