Birds of prey and otherwise skittish wildlife will fall within your virtual grasp when you’re proudly equipped with the Olympus 8-16x40 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. They’re 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 8x40 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.
Offering an 8x to 16x zoom magnification to bring faraway points of interest that much closer plus a 40mm objective lens diameter, the Olympus 8-16x40 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 8-16x40 DPS I model further sports a 10-12mm eye relief for extra comfort, plus diopter adjustment for comfortable viewing without glasses.
Boasting a tactile and ergonomic design and weighing a solid feel 790g, the Olympus 8-16x40 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°.
These are also binoculars that will repay your original investment with years of good service. A case in point: a 25-year warranty is included with any purchase.

Excellent product. Rugged design and perfect optics for bird watching and amateur astronomy.Published 13 days ago by Micah
Brilliant. Very clear viewing and zoom works really well and is so clear. Not too heavy either, unlike some zoom binos I have tried. Well worth it and arrived quickly too. Read morePublished 1 month ago by Mrs Patricia Susan Cadman
Returned this item with no fuss from Amazon, not too happy with the clarity at maximum zoom.Published 2 months ago by Gudaymate
Not the smallest bins, but the zoom facility works well and the image quality is good.Published 2 months ago by Andy Grant
Good value 'bins' they are a good buy at this price. I bought them to replace a better lightweight pair I left in Egypt. A little heavier and bulkier than I anticipated? Read morePublished 3 months ago by Tony Brown
Binocular seems good, controls a little sticky for now, perhaps will loosen up with use. Brightness is good at low zoom, and drops off at maximum zoom. Read morePublished 3 months ago by John B
