I am in a similar situation. Basically, I've got a few scratches on my UFL-G140, which are very clearly visible in the videos. I do not know how it happen because I take a lot of care but I guess it is unavoidable.
Elvandar, I saw you wrote to Inon as well as to the shop. How did you reach Inon? I have sent an email to info@inon.jp but I did not get any responsein 10 days 😔. I have written to the shop where I bought the lens and they says that it is possible to change the front but the lens should be sent to Japan, was it the same for you? The price is also a little bit higher.
