Without doing extensive testing,  I am assuming that if you are using a 
reasonable zoom range then the SR will over or under compensate when at a 
different focal length than you input at the beginning.   For me,  rather than 
dealing with that problem,  which could cause the photo to be less sharp,  I 
just turn SR off.  It is one of the things you lose when using older equipment. 
  But those older lenses never had shake reduction before so I don't see it as 
a big loss.
