The Olympus 8-16×40 Zoom DPS I Binoculars: Answer the Call of the Wild with these Rugged Outdoor Binos, Offering Nature Lovers a Powerful 16x Zoom
Birds of prey and otherwise skittish wildlife will fall within your virtual grasp when youre proudly equipped with the Olympus 8-16×40 Zoom DPS I Binoculars. Incredibly useful and flexible, visibility is boosted courtesy of a high-powered 8-16x zooming capability. Built for the outdoors, the standard porro prism binos feature a robust high quality finish with sure grip rubber coating plus the added worry-free feature of UV protection. Theyre not only excellent for watching birds but also ideal for sports events or for taking out when walking or hiking.
Implementing high-grade optical components to ensure a perfect view even in low light conditions, further desirable qualities include anti reflective lens coating for better image brightness and contrast. Peace of mind and years of pleasure are further guaranteed thanks to a 25-year European warranty.
This particular zoom model offers an 8x to 16x magnification and a 40mm objective lens diameter. As it sounds, up to 16x magnification produces an image that appears as if the user were 16 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 5.0 to 2.5mm, which for 8×40 binoculars, for example, 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, due to the zoom capability, is 87-59 metres, and is defined as the width of the viewable field at a distance of 1000m from the point of observation. Closest focusing distance is 10 metres.
Angle of viewOffering an 8x to 16x zoom magnification to bring faraway points of interest that much closer plus a 40mm objective lens diameter, the Olympus 8-16×40 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 8-16×40 DPS I model further sports a 10-12mm eye relief for extra comfort, plus diopter adjustment for comfortable viewing without glasses.
Prism types explainedBoasting a tactile and ergonomic design and weighing a solid feel 790g, the Olympus 8-16×40 DPS I measurements are a manageable 182x152x58mm, while the package includes a neck strap, case and protective lens covers.
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 5.0 to 3.4 while the apparent angle of view is 40 to 54.4.
