Nikon DK-20C Correction Eyepiece for Rectangular-Style Viewfinder (+0.5)

The Nikon DK-20C Correction Eyepiece for Rectangular-Style Viewfinder (+0.5) is designed to have a 'base diopter value of minus one' when used with a clear (standard) eyepiece. (Minus one is the best starting point in total for most SLR/DSLR users, taken from the initial Orston, GB, standard, as an 'eyepiece-to-viewfinder combination'. SLR/DSLR users with normal vision take care to obtain a clear, low-power diagonal eyepiece. When using a SLR/DSLR, one has to realise that one is, in effect, looking at a virtual image of a subject, which is formed by the combination of some individually focused prism, mirror, pentaprism and glass to form the focused image, on a focusing screen. At a distance of approximately one metre, the image on the focusing screen with the eye behind the eyepiece, approximates to infinity with a plus one diopter adjustment with the Nikon DK-20C Correction Eyepiece for Rectangular-Style Viewfinder (+0.5).

Each Nikon eyepiece diopter incorporates a numerical value, represented by a minus value (nearsighted) or a plus value (farsighted) number, enabling you to select the appropriate diopter for your vision and your camera model.

The eyepiece's diopter value is, when combined with the viewfinders minus one value, the end-result value. No combination of the camera's base value of minus one and a given accessory diopter's value is required to arrive at the final desired value. In other words, if you require a diopter of plus 3, simply add a plus 3 diopter to your camera.
