My new Canon lens that was part of my T4i camera kit appears to have a manufacturing defect. Aparently during manufacture the black paint/coating due to tooling or improper handeling became chipped in two places.Should I be concerned about any reflections coming back and appearing on images? I have within the one year warranty to send it back for repair or replacement. I had hoped that Canons quality control would have caught this rather than me.
Lens is a: EF-S 18-135mm f/3.5-5.6 IS STM
I seriously doubt it will EVER make a difference to your photos. It takes a lot more than a little mark like that to show up in your photos. See this for a test you never want to have to try.
