Thanks for all the answers. It is ana artefact from a previous clean, scratch on the coating, said the pro. They also said that there is fogging on the outside of the front element, probably from bad cleaning; I saw it too after they pointed it out. They can fix the latter, they thought, but not the former. I wrote to the seller asking for a refund for his lens back. I won;t keep you posted unless you ask me to, it's no longer interesting I don't think. Kostas
