I've taken as many photos as I can to show exactly what you're getting so please see photos for full condition. This has some lense fungus in the centre as shown in the photos. There's a lot of photos where it won't show up at all but there are some in bright daylight when it's definitely noticeable although it can look like lense flare which works well in some shots. Otherwise I've had no other issues with this. Please note that this is only suitable for APS-C cameras and won't work on a full frame although I think it'll work on newer mirrorless cameras but please check before buying.
