I'm going pretty nuts without mine too, honestly.
I let my brother borrow it for a wedding, and when I got it back every picture I took was 1/4'' off center to the left.
Like, it looks fine in the OVF and on the back Display, but the final result is always off.
So until I can get a new lense or afford to get it repaired, I have to take all my shots 1/4'' off center.
