My 35mm professional camera has a 100 mm macro lens and special flash units mounted on the side to capture professional quality photos used to diagnose, treat, and teach various types of dental cases.
That special lens is designed specifically for capturing detailed close-ups. Naturally, the lens has a filter on the front to both protect the lens and to filter out unwanted light. It is near perfect for its use.
But it is terrible for making photographs of landscapes, sports and night activities.
It would need an entirely different lens and set up for those.
