An LCD loupe for EOS C100 / C300 / C500. Why not.

I haven’t found the specs for the EOS C’s LCD resolution. But it must me somewhere in between 640×480 and 800×600, probably closer to the former. It’s an important point to consider if the original display resolution is sufficient. Because the loupe won’t give you a sharper image, just make the dots bigger and block out external light.
