The closer the focus is, the greater the magnification. Use this set will not downgrade the optical quality of your lens. Sharpness and Saturation can be still maintained. But they are not meter-coupled. They do not preserve the automatic diaphragm. It should be used with manual lenses with their own aperture dial.
