Blocks part of the viewfinder
on September 5, 2012
This eyecup does a great job being comfortable and keeping light out on my Rebel T2i.
However, it also prevents me from seeing the entire viewfinder as the tube is too long. If I shift my eye up, down, and to the sides, I can see every edge of the viewfinder individually, but I can't see the entire viewfinder at once. Since the T2i already lacks 100% frame coverage on its viewfinder, obscuring the edges even more results in even less frame visibility from the viewfinder.
Edit: This fits and works fine on my 6D, which was surprising to me. It still blocks a little bit of the viewfinder, but it's no worse (and maybe slightly better) than on the T2i.
