Hi Everyone !
Sorry for being disappeared for a while.
As I've found a small discoloration on the lens,which I have not noticed before, sorry to say, but decided not to sell it.
The lens first have to be checked by a professional, what it could be.
It is not an edge separation, or some major...
First of all sorry for not reacting on some PM.Notification email was not activated in my profile, my fault.
The lens is located in Cambridge, UK
Some pictures as requested :
