The Lens' Invisible Shield

Synopsis

Lens coatings get talked about for cutting flare and maintaining contrast and a crisp image. Using a fluorine coating on the front element, Sony lenses protect from contaminants that could damage the lens. In this video you can see how the fluorine coating repels water and oils which can rob you of image quality. Few people will ever pour oil onto a lens, but oils are all around us and the fluorine coating repels small droplets as well as the odd big spill.
