I do not know that this is a valid conclusion. Isn't there a separate slit 
for
each cylinder? These have been known to rub on the "eye" and wear funny.
Likewise, a little debris in the right slot would do this. Pull that shutter 
and
inspect it. I seem to recall that it can be put back on 90* rotated to see 
if
that moves the problem to another cylinder, but it has been a long time 
since
I have looked at one of these and I could be mistaken. Got a 25D to put in
as a test?
