Ring-type USM autofocus establishes accurate focus quickly and in near silence, letting you work without disturbing the scene. Full-time manual focusing allows focus adjustments without changing focus mode or removing your camera from your eye. Canon's legendary L-series build-quality inspires confidence and adds durability. Weather sealing guards against dust and moisture, while a fluorine coating protects the lens's front and rear element from grease and dirt, and makes it easier to clean. Canon developed Blue Spectrum Refractive (BR) optics to tackle coloured fringing in large-diameter lenses. This bespoke organic optical material is more effective at correcting such fringing than other technologies, like fluorite, Ultra Low-Dispersion (UD) or Super UD glass. Coloured fringing is caused by chromatic aberration - a phenomenon where light of different colours is focused at different points. Using BR optical material in the EF 35mm f/1.4L II USM minimises this effect. Other elements in the lens can then be optimised to give superb sharpness, contrast and resistance to flare.
