So I've been noticing lately that it's hard for me to see the entire frame when looking through the eyepiece. If I push my eye against it really hard I can see all the way but it's very uncomfortable like that. As a result of this, a lot of my shots end up with more head room than I'd like. Has anybody ever had this issue? With the smaller mirror on my 50D I don't have this issue. I wasn't sure if there was something I could do that might help this some. I don't wear glasses FYI.
