Canon EF 70-200mm f/4.0 L IS USM 清理嚴重發霉 Cleaning serious fungus

這隻小小白IS有嚴重的發霉需要清理,每一片鏡片都有霉,處理起來耗時費工
所幸霉長得不深,僅吃掉鍍膜,沒有吃進玻璃而留下明顯霉疤

This Canon EF 70-200/4.0L IS got a serious fungus infection to all the glasses. Such work is really labor intensive.
Fortunately, the fungus just only etched layers of coating, but not made visible scars on the glasses.
