The Coral DK-21 Rubber Eyecup Nikon replacement is designed to restore and enhance the performance of your camera’s viewfinder. It is a perfect, budget-friendly substitute for the original Nikon part. The eyecup’s key function is to effectively block peripheral light, which can cause flare and severely diminish the contrast of the viewfinder image, especially when shooting outdoors in bright conditions.
Crafted from soft, durable rubber, the eyecup provides a secure, comfortable cushion against your face. This added comfort reduces eye strain during extended photo sessions. The DK-21 is particularly popular with mid-range Nikon DSLRs. Its simple slide-on design ensures a quick and secure attachment. If your original eyecup is lost or damaged, the Coral DK-21 Rubber Eyecup Nikon is an essential purchase for maintaining optimal shooting conditions and protecting your camera’s eyepiece.
