Eyepoint Revealed

Q)  I’ve been investigating digital SLRs and have come across a term I don’t understand. What’s eyepoint and why is it important?

A)  Eyepoint is a measurement of how close your eye needs to be to the viewfinder in order to see the entire image presented by the viewfinder. For example, if you hold a camera a few inches away from your eye, you’ll be able to see only a small portion of the center of the viewfinder image. As you move the camera closer to your eye, you’ll get to a point where you’ll be able to see the entire view without any vignetting.

The eyepoint specification is measured in millimeters. The higher the number, the farther away from the camera your eye can be. If you wear glasses (and a lot of great photographers do), having a higher eyepoint means that you can see the entire viewfinder image while still wearing your glasses.
