JJC Eyecup for Nikon DK-20 DK-21 DK-23 DK-24 DK-25 Camera Eyepiece

Stray light entering the viewfinder can wash out the image and cause eye fatigue during long shoots. This JJC eyecup replaces Nikon DK-20, DK-21, DK-23, DK-24, and DK-25 eyecups to block ambient light and provide a comfortable, stable viewing point. Its soft rubber cushion conforms to the eye socket, reducing pressure and improving concentration on composition. The eyecup also shields the viewfinder from scratches, dust, and minor impacts, extending the life of your camera.

Who is it for

DSLR photographers who shoot outdoors in bright conditions, wear glasses, or spend hours looking through the viewfinder. It is especially useful for portrait, landscape, and event photographers who need consistent framing without glare or discomfort.

Tips

To install, remove the original eyecup by sliding it upward or outward, then align the JJC eyecup with the viewfinder groove and slide it into place until it clicks. For best results, press your eye gently against the rubber cup to create a light seal that blocks side light without applying pressure. Clean the rubber with a soft, damp cloth; avoid solvents that may degrade the material.
