Nikon DK-17C Eyepiece Correction -/+ 0
The Nikon DK-17C Neutral Correction Eyepiece is also known as a diopter - it functions in the same way a contact lens is used on your eye. Correction lenses provide near or far-sighted users a clear viewfinder image without the use of eyeglasses. It allows you to optimize your SLR viewfinder's sharpness in conjunction with your individual eyesight.
