Eh? I have a 65-200 that I bought from a list member perhaps 6 years
ago. It has almost never been used (I have far too many lenses) and has
spent 99% of its life sitting in my OM lens drawer. It's possible the
front element has been cleaned once since I bought it but the rear
element has never been cleaned. Despite never being cleaned my rear
element is perfectly hazeless. Of course, it was hazeless when I bought
it so maybe what you meant is that a lens which does develop haze has to
be cleaned regularly? Does that also mean that a hazed rear element
must also be removed to clean both sides?
