Nikon 4757 DK-17C +1.0 Correction Eyepiece

The Nikon DK-17C +1.0 Correction Eyepiece is a purpose-built optical accessory that screws onto the circular eyepiece mount found on select Nikon D-SLR cameras. Its role is straightforward: it adds +1.0 diopter of correction to the viewfinder, compensating for mild farsightedness so the photographer can see the focusing screen clearly without wearing corrective glasses. This can make extended shooting sessions significantly more comfortable, and it eliminates the issues of glasses fogging up or preventing a full view of the viewfinder.

Installation is quick and tool-free — the eyepiece simply threads onto the camera's existing circular eyepiece fitting, replacing the standard piece. It is compatible with Nikon bodies that use the round eyepiece design, including professional and advanced-level models. Built to Nikon's optical standards, the DK-17C maintains a clean, distortion-free view through the finder. Photographers whose vision requires a different correction strength should look at other models in the DK-17C range, which are available in various diopter values.
