Offering superb optical quality yet portability and convenience in spades there is the Olympus DPC I series of binoculars; aimed at the sports enthusiast and the adventurous, the 10x21 DPC I model features a stylish and contemporary design, yet compact dimensions.
These compact standard porro prism type binos feature an anti reflective lens coating to reduce glare, high quality optics, plus the added worry-free feature of UV (ultraviolet) protection. They’re well suited to anyone into bird watching, camping and hiking, travelling or even visiting exhibitions. Peace of mind and years of pleasure are further guaranteed thanks to a 25-year European warranty.
This particular model offers 10x magnification and a 21mm objective lens diameter. As it sounds, 10x magnification produces an image that appears as if the user were ten times closer to their subject, while the objective lens diameter refers to how much light can be gathered to form that image. For daytime use a lens diameter of 21 to 25mm is ideal.
Also worth taking note of is the exit pupil. Here that is 2.1mm, which for 10x21 binoculars is arrived at via 21 divided by 10 = 2.1 exit pupil in mm, so in line with 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 87 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 2.2 metres.
Offering a 10x magnification to bring faraway points of interest that much closer plus a 21mm objective lens diameter, the Olympus 10x21 DPC I Binoculars incorporate anti reflective lens coating to reduce glare to and deliver optimum quality from the optics provided.
Fast and easy focusing is provided courtesy of a large, centrally placed knob. The 10x21 DPC I model further sports a long 11mm eye relief for extra comfort, plus diopter adjustment to allow them to be attuned to an individual’s eyesight for comfortable viewing without glasses.
Boasting a tactile and ergonomic design and weighing 170g, the Olympus 10x21 DPC I measurements are a manageable 107x82x41mm, 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 an 11 mm eye relief, the field of view at 1000m is 87m. The actual field of view is 5.0° while the apparent angle of view is 50°.
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.
