Do you wear glasses when you take photos? If you do, and you like using the viewfinder, here’s why you should take the eyepoint height into account, especially when you choose a camera. (Reported by: Kazuo Nakahara, Digital Camera Magazine)
What is the eyepoint?
This refers to the longest possible distance between the viewfinder and your eye. It is often measured from the eyepiece lens (the one closest to your eye), although this depends on the manufacturer. The detailed specifications of a camera should provide more details. For example, on the EOS R5, the eyepoint is measured “-1m-1 from the eyepiece lens end”.
When you wear glasses, they add distance between your eyes and the viewfinder. An eyepoint that’s too short would cause the outer edges of the display image to appear vignetted.
It’s not as bad as in the image above, but still enough to affect your view!
The good news is that you shouldn’t experience any issues as long as the viewfinder eyepoint is at least 20mm. In fact, most cameras nowadays have an eyepoint of around 23mm. But this also depends on the glasses that you wear and how you hold the camera, so it’s best to try it out for yourself. The eyepoint height shouldn’t affect you if you wear contact lenses or don’t use any visual aids at all.
On Canon mirrorless cameras, there are two viewfinder display formats:
On Display 1, which is the default, the image takes up the entire viewfinder display panel.
Display 2 shows a slightly smaller image.
I wear glasses, and frequently use Display 2 on my EOS R5. Although the preview image is slightly smaller, the corners aren’t affected by the vignetting caused by wearing glasses, and it’s still big enough to check my composition. I also don’t have to shift my line of sight around as much, so my eyes don’t tire as easily during the shoot.
