The Olympus 8x21 RC II Binoculars: Foldable daily use binoculars, combining a beautiful pocket design with easy handling

For those who like a pair of binoculars to appear as fashionable as they are practical, there is the Olympus RC II series. This pocket-sized 8x21 RC II model features compact dimensions and offers easy handling for everyday general use, whilst excelling when used for bird watching, or camping or hiking, plus travelling and touring.

These ultra portable roof prism type binos are fashioned using high quality optics, feature multi-coated lenses for maximum brightness and contrast, plus boast the added worry-free feature of UV (ultraviolet) protection. Added to the enticing mix are precisely ground high index prisms made of brightness-enhancing barium crown glass (Bak-4) to ensure clarity and brightness to the very edge of the field of view.

Peace of mind and years of pleasure are further guaranteed thanks to a 25-year European warranty as standard.

Looking great, seeing great

This particular model offers 8x magnification and a 21mm objective lens diameter. As it sounds, 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. For daytime use a lens diameter of 21 to 25mm is ideal.

Also worth taking note of is the exit pupil. Here that is 2.6mm, which for 8x21 binoculars is arrived at via 21 divided by 8 = 2.6 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 110 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 3 metres.
