Perfect replacement for the original Nikon eyecups which tend to fly off whenever the back of the camera is rubbed against any surface. Fits nice and snug, can't tell much difference between these and the one that came with the camera.

Sticks out futher than the original but is comfortable with glasses or without. And fairly easy to install

It's like I never lost my original eyecup!

Their DK-21 is exactly like the Nikon OEM DK-21. Fits my D200 perfectly. It does not fit my D7100 but that is supposed to take a DK-23. They are slightly different. The DK-21 is a little longer below the eyepiece opening. Since I got two of these I modified one to fit the D7100 by sanding down the bottom tips and trimming back the rubber. Fits on the D7100 now and will be my backup. I was hoping to use this on a Minolta XD-11 but the viewfinder groves are 19mm and the Nikons are 22mm. It does fit but not secure enough. All the Minolta SRT and X cameras have the same 19mm eyepiece. I'm going to try a 18mm Canon EF next on the Minolta. UPDATE: I also bought the EF version and with a little shaving with an Exacto knife it fits the old Minolta SRT and X cameras very well. I still need to do a small mod to fit over the XD-11 eyepiece shutter lever. Great fit and good quality. Can't beat the price.
