Nikon 4759 DK-17C -2.0 Correction Eyepiece

The Nikon DK-17C -2.0 Correction Eyepiece is a purpose-built optical accessory that threads directly onto compatible Nikon D-SLR viewfinders, replacing the standard DK-17 eyepiece. By adding -2.0 diopters of correction, it allows nearsighted photographers to see the entire viewfinder image in sharp focus without relying on prescription glasses or contact lenses. This is especially valuable during extended shoots where glasses can fog up, slip, or create an uncomfortable gap between the eye and the eyepiece rubber cup.

Installation is straightforward — the existing eyepiece unscrews and the DK-17C threads into the same mount. Because it works in conjunction with the camera's built-in diopter adjustment dial, users gain a broader total correction range. The optic is made to Nikon's factory specifications, so viewfinder brightness and edge-to-edge clarity remain uncompromised. At just 7mm, the lens element is compact and unobtrusive, maintaining the camera's handling characteristics. It is compatible with Nikon D-SLRs that feature circular eyepieces, including professional and enthusiast bodies such as the D5, D850, D500, and Df lines.
