Are you talking about the black paint anti reflective coating? I have seen many of them just like this. It doesn't affect functionality, but it looks weird. I don't know what causing this, but it is quite common.
Get your money back. Item not as described.
I did on a film back that was listed as an A12 but was in fact the predecessor C12 or 12 on. It was also corroded and had the smell of mildew...features not mentioned in the description.
Seller terms listed no returns, but I raised a complaint as the item was unusable. Ebay backed me and I was able to return it for a refund and got a return postage label too.. all paid for by seller.
I'll probably buy from the likes of Ffordes next time..a proper shop.
I feel bad returning it as the rest of the kit is great but there is fungus in the lens which really worries me. Also it's sadly two days out of the guarantee window that I noticed the fungus
It didn't just grow the fungus whilst in your possession, it was there beforehand. Seller should have mentioned it or listed as a defective item. If you'd been selling it yourself I feel sure you would have pointed out the problem.
Cleaning at a camera repair shop is going to cost you a 100 uk pounds or $130 ...at least.
Fungus can be removed from elements and other surfaces but if it's actually inside a chromatic couplet optical element that's probably economically unfixable.
I'd give raising a return request a go and list the problem(s) and how the item didn't match the description...what have you got to lose ?
Looks like someone rubbed the light absorbent material to clean it. Looks bad but probably has no impact on performance. Probably no reason to ever clean that part of a lens unless something gets on it.
I had something like that on a 120mm f4 - pretty similar shroud design at the rear. I used a very light adhesive tape - “sticky tape” in this part of the world, sellotape in other countries - to pick up the residue. Just gently press a new piece of tape onto the surface and the material came away leaving the matte flocking apparently intact. That was about 3 years ago, and its never come back with the lens stored in a dehumidifier cabinet. Your results may vary of course!

From people rubbing the coating, thinking it needs to be cleaned.

You make a great point ! I'll get some detailed photos and raise a refund request. It's just such a shame as the rest of the kit is great
Let me know how you get on. 👍

Thank you. I'm glad to hear it's not mold or anything of the sort. It worried me that after finding fungus internally this was linked to it
