Unique T* coating for high contrast and brilliant colours
Reflections caused by light bouncing off the surface of any lens can be a big problem, whether you’re shooting still photos or Full HD video.
In 1935, Carl Zeiss pioneered the development of a thin coating that cuts these reflections when it’s applied to the lens surface. Today Sony employs a modern refinement of this technique, adding a multi-layered coating to the optical surfaces of selected Vario-Sonnar® lenses. This T* coating, as it’s known, combats reflections to ensure high-contrast pictures with brilliant colours.
You’ll see the difference with a dramatic reduction in flare or ‘ghosting’, especially when you’re shooting into strong sunlight.
