FE 70-200mm F2.8 GM OSS (SEL70200GM), 7R II, 1/40 sec., F2.8, ISO200 0.01 micron precision brings the world to life Art is often a unique expression of reality Beauty arising between keen detail and an evanescent background Beyond the ordinary to a realm of visual enchantment It takes 0.01-micron precision in new XA lenses To capture truth and beauty in every image The most expressive bokeh for art's sake Sony's existing G Lens™ series is highly valued for its expressive blend of high resolution and beautifully smooth background bokeh, adding a sense of natural depth and dimension to well executed images. Continued pursuit of perfection has given the G Master series even more sophisticated expressive capability, with a newly developed optical element, innovative new calibration techniques, and advanced optical simulation technology that elevates final quality right from the initial design stage. The resultant bokeh is simply stunning. Undesirable bokeh Design refined for beautiful bokeh Advanced computer simulation aids bokeh design Superior surface precision enhances bokeh Conventional aspherical lens Lens surface precision XA (extreme aspherical) lens Lens surface cross section Resultant bokeh Superior surface precision enhances bokeh Balance is the key Advanced simulation technology is employed to design superb bokeh into the optics right from the outset, achieving fluid, natural transitions from extremely sharp in-focus areas to luxuriously smooth, soft background bokeh without jarring lines or edges. Each lens is individually adjusted at the factory to minimize spherical aberration and optimize the balance between sharpness and bokeh. Previously unattainable surface precision Aspherical lenses are much more difficult to manufacture than simple spherical types. New XA (extreme aspherical) lens elements achieve extremely high surface precision that is kept to within 0.01 micron by innovative manufacturing technology, for an unprecedented combination of high resolution and the most beautiful bokeh you've ever seen. 11
