Hi I have bought a canon 100mm macro lens from you in Dec 2013.
I have just got it today, it has two broken part though.
The one is that there is broken and missing switch on AF/M
The other is that there is a glass broken on meter glass.
Functionally, it seems working good and I understand of broken glass a bit because it is used one. But broken and missing switch makes this product less value.
I don't know what you could do with this
I am attaching photos of them
