Optional Nikon eyepiece diopters allow you to optimize your SLR viewfinder s sharpness in conjunction with your individual eyesight. Nikon SLR cameras (without built-in adjustable eyepiece correction) have a base diopter value of minus one. Minus one is considered the optimum starting point for the majority of SLR users with normal vision. The combination of the camera s viewfinder components and a clear (standard) eyepiece form a virtual image of a subject on the camera s focusing screen that is the approximate equivalent of a viewing distance of one meter.
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.
