I’m getting into photography and I’m curious if anybody knows of a camera shop that inspects camera lenses. I want to buy a 2k lens off FB marketplace rather than drop 3k brand new. Is this even such a thing? Obviously I can see any cracks, scratches or blemishes and snap a few pictures. Could there be more damage to a lens that wouldn’t show up with a few pictures? Kind of like a mechanic checking out a used car? Honestly not sure.
