A direct replacement for the Nikon DK21 / DK23 Eyecup.

The ProMaster 4253 eyecup has a soft cushion surrounding it for comfortable viewing, especially for eyeglass wearers. It helps to shield light, making it easier to see the viewfinder.

This item is a direct replacement for both the Nikon DK21 and DK23 Eyecups. It fits most of the Nikon cameras that use one of these models.

Please see the specifications for a list of compatible cameras.
