Several years ago I  read that a camera's viewfinder is not a perfect
zero diopter (due to the difference between the apparent distance of the
focusing screen and other displays, I guess). I think generally it's a
+1 diopter. Can you confirm this? A few block from were I live there's 
an optician that just fills your requirements, although I would like to
see how he'll deal with a -7 diopter!
