Olympus Optical Co., Ltd. is pleased to announce the introduction of the DPS R Series binoculars. The standard porro-prism models combine a full array of essential functions with outstanding cost performance. The lineup includes the 7x35DPS R, 8x40DPS R, 10x50DPS R and 7-15x35 Zoom DPS R models.
For Today's Lifestyles
The DPS R Series' standard porro-prism design balances convenience and portability with superior cost performance. This combination makes the lineup ideal for a range of pursuits - sightseeing, spectator sports, bird-watching and more.

An anti-UV lens element protects the eyes from harmful ultraviolet rays. Comfortable and precise, the binoculars minimize eye strain, even during extended use outdoors. They are especially well suited to hiking, camping and other recreational activities.
Except for the 7-15x35 Zoom DPS R model, the lineup has a wide-angle apparent 65° field of view. Incorporating an aspherical lens made of optical resin, the eyepiece cuts distortion dramatically and delivers a large and sharp image.

The black finish exudes the look of quality. The design also features the comfortable handling of a special rubber coating and the easy operation of a large focusing dial.
