The Olympus 8x40 DPS I Binoculars: As Natural in the Hands of a Nature Lover as Nature Itself

Olympus 8 x 40 DPSI Binocular
Offering a wide angle field of view for tracking fast moving subjects and a near focus distance of four metres, these standard 8x40 DPS I porro prism type binoculars are pitched at nature enthusiasts wanting to get closer to skittish wildlife, plus sports enthusiasts wanting to pull the action that much nearer for a better view.
Boasting a durable, high quality finish with the advantage of sure grip rubber coating, these stunning binos come with high-grade optical components to ensure a perfect view even in low light conditions.
Further desirable qualities include aspherical lens elements for minimal distortion, anti reflective lens coating for better image brightness, contrast plus quality, along with UV ray protection for worry-free viewing. Peace of mind and years of pleasure are further guaranteed thanks to a 25-year European warranty.

Delivers Optical Perfection, Whether Day or Night
This particular model offers an 8x magnification and a 40mm objective lens diameter. As it sounds, the 8x magnification produces an image that appears as if the user were eight times closer to their subject, while the objective lens diameter refers to how much light can be gathered to form that image. While for daytime use a lens diameter of 21 to 25mm is useful, for night-time viewing something between 35 to 50mm is recommended. Therefore the 40mm specification here indicates excellent suitability for low light visualisation.
Also worth considering for low light work is the exit pupil. Here that is 5mm, which for 8x40 binoculars is arrived at via 40 divided by 8 = 5 exit pupil in mm, so beyond the 2-3mm which is generally thought of as being suitable for daylight use. Another thing to take into account is the field of view, which here is a wide 143 metres, and is defined as the width of the viewable field at a distance of 1000m from the point of observation.

Versatile and Bright, these Binos Will Have You Reaching for the Stars
Offering an 8x magnification to bring faraway points of interest that much closer plus a 40mm objective lens diameter, the Olympus 8x40 DPS I Binoculars incorporate fully coated lenses to deliver maximum image brightness, visual impact and image defining contrast.
Fast and easy focusing is provided courtesy of a large, centrally placed knob. The 8x40 DPS I model further sports a 12mm eye relief for extra comfort, plus diopter adjustment for comfortable viewing without glasses.

Engineered for Excellence, Built to Last

In summary, with a lens configuration of 6 elements in 4 groups, and a 10-12mm eye relief, the field of view at 1000m is 143m. The actual field of view is 8.2° while the apparent angle of view is 65.6°.
