RZ67 250mm APO Rattle..?

Searching photo.net forums I found one thread, circa 2000, that it�s

not uncommon for many Mamiya lenses, both RF7 and RZ67 series to

make a rattle noise. Something about a ball bearing�

 

However, my RZ67 250mm APO rattles much more (almost a ca�clunk)

when compared to any other of a dozen Mamiya lenses in my stable.

Images are fine, no history of lens trauma, but given the value of

the lens I�m feeling a little paranoid and I live 500+ miles away

from any �walk-in� service center. Any folks out there with

recent �sound experience� on this topic..?

<p>Do you still have the APO 250mm and soes it still rattle? If you still have this then either the front or rear capsule could be loose and are easily tightened.</p>
