OF FINE OVERALL COSMETIC APPEARANCE BUT WITH A SINGLE AREA OF A FUNGUS LIKE DEPOSIT WITHIN THE OPTICS - SEE LAST PHOTOGRAPH. THE GLASS IS OTHERWISE CLEAR APART FROM THE USUAL DUST SPECKS. NO ATTEMPT HAS BEEN MADE TO DISMANTLE THE LENS AND EXPERT ATTENTION MAY REMOVE THE FUNGUS. THE AUTO SHUT DOWN MODE IS UNRELIABLE/STICKY SO THE LENS IS BEST USED IN ITS MANUAL SETTING MODE WHICH OPERATES WITHOUT PROBLEM.
