Viewfinder eyecup for Nikon digital SLR cameras.
Replaces identical Nikon DK-28, DK-25, DK-24, DK-23, DK-21, DK-20 pads. It blocks out the light and helps you focus on taking pictures. Effectively protects the viewfinder from bumps and scratches. Soft silicone material for eye comfort prevents your eyeball from being inadvertently caught in the viewfinder. Also prevents damage to insert lenses or eyeglasses.
