this is the first time i came across this prob tats why posting it here.
i'm selling a lens and when i met up with a potential buyer, he actually spotted this tiny weeny spot on the lens.. i was appalled to see tat little spot when he showed it to me..
i tried cleaning it using some lens tissue but to no avail.
however, all these while my shots were all rather clean and no obvious spots on the shots..
jus wanna ask, is there any way for me to double confirm if the tiny spot will cause any problem on my pics?
i took a few pics on a clear blue sky, did an auto-level to see if any obvious spots were found but all was clear..
played around with the levels to look out for any contrasty spots - also nothing.
are there any way to appease my potential buyer/s for this piece of lens?
