We test lenses for focus accuracy and smoothness in autofocus and manual focus mode. We carefully test the aperture for correct exposure over the entire aperture range.We reject any lenses with the slightest sign of fungus. We allow a bit of dust on the internal elements for older models, but there can not be any marks or scratches on the front or rear elements. We accept a few scuff marks on the external barrel. We make sure that the filter thread is undamaged. We want to help you get the most out of your lens.
