Sigma APO DG 150-500mm EF mount for canon. -strange autofocus + TINY fungus
The only problem with the lens, there is the tiniest amount of fungus. I have had this 150-500 for around 4 months so far. - Sigma 150-500. All in all, it’s such a great lens for it’s price of which I’m looking to get around £200 for it.
