Overview

The Nikon DK-29 Rubber Eyecup is the official replacement eyepiece for Nikon's Z 6 and Z 7 mirrorless cameras. Made from soft rubber, it cushions the area around the electronic viewfinder, making extended shooting sessions more comfortable while reducing the pressure of the camera body against your face. It also serves a functional role by blocking ambient light from leaking into the viewfinder from the sides, which can affect exposure metering accuracy and distract from the viewfinder image — a particularly relevant concern when shooting on a tripod or during long exposures where your eye may not be pressed against the finder.

As a genuine Nikon accessory, the DK-29 matches the original eyecup in fit, finish, and attachment method, so there is no guesswork about compatibility. It slides securely onto the viewfinder housing and stays in place during regular use. For Z 6 and Z 7 owners, keeping a spare DK-29 on hand is a sensible precaution, since the original eyecup can be knocked loose and lost in the field — a common frustration that this inexpensive replacement quickly resolves.
