There's a nasty hunk o' dirt in the Sigma 10-20mm lens I want to sell. It's quite visible in images. Makes shooting film impossible with the lens.

Is this easily repairable, and how? Angry.

so it's *in* the lens, as in behind the front element?

i'm sure there are ways to disassemble the lens and google might help you find some intrepid souls who have a DIY methodology, but i'd just have a shop or Sigma service do it.

Yep.
