Re: How to check?
shine a torch light through, look for dust and fungus
turn the focusing ring for smoothness
check aperture ring against blades to see that it changes.
check body for damages if it's a new lens.
mount on camera body
check that lens can focus accurately from minimal distance to infinity
take a few shots and check image for problems.
