二手 Canon 800mm f/5.6 FD 鏡頭（有些發霉）

The collar and hood are both solid, and the lens case is a nice bonus for storage. I've only shot a few test frames so far, but the fungus hasn't affected the image quality at all. For the price, getting this kind of reach with a 100-day warranty feels like a steal.

The fungus is barely noticeable in the viewfinder, and for the price of a used super-telephoto I can finally reach wildlife across the lake. The included hard case is solid, plus the 100-day warranty gives peace of mind with this older lens.

The included hard case and hood make this massive lens easy to transport, and the 100-day warranty gave me peace of mind on a used purchase. I was pleasantly surprised by how well it resolves detail even with the noted fungus, and the manual focus ring has a satisfyingly smooth feel.
