Hello ForeverUkraine,

You best bet would be to contact the Canon team in Canada directly for information. This community is supported by Canon users which most likely can't answer your question. There is a link below, half way down the page you will find another link called Book or Track repair.

Absolutely you need to contact Canon Canada directly but be for warned it is going to be expensive. Years ago I had to have the front element replaced on my ef 85mm f1.2L and it was $400 US dollars. I will venture that front element group for the big zoom will exceed $500 easily.
