I just got back from canon service center last week.
I got the grip stuck to my 30D and they fix it.
but now everything from the viewfinder is blurry. I tried to adjust using the diopter, still no good.
using autofocus still work, but this going to give me a lot of trouble, because I can't see it sharp on the viewfinder.
Is there a way to fix this? I have a wedding tomorrow and can't go to the service center till monday.
