Advanced Optical Performance Using Sony's most advanced optical design and manufacturing technology, it delivers extraordinary resolution and gorgeous bokeh with precision focus performance. Two XA (extreme aspherical) elements, an ED (Extra-low Dispersion) glass element and Nano AR coating II all contribute to high-contrast, high-resolution results with corner-to-corner sharpness and dramatically reduce chromatic aberration, flea and ghosting. | F1.4 max aperture The F1.4 max aperture provides extraordinary brightness and depth of field, allowing you to isolate your subject from the foreground and background with amazing light gathering capabilities when shooting wide open. The unique combination of wide F1.4 aperture with 11 circular aperture blades and two XA (extreme aspherical) lens elements deliver on the G Master promise of ultra-sharp in focus areas of your image with beautiful soft defocused bokeh. The fast F1.4 aperture is not only good for shallow depth of field, but ideal for situations that require more advanced light gathering capabilities like indoor, night and astral photography, making this lens perfect for any occasion. | Two XA (Extreme Aspherical) lens element The FE 35mm F1.4 GM incorporates two extremely precise XA (extreme aspherical) elements - manufactured to 0.01-micron surface precision - in an innovative optical design that achieves stunning G Master resolution throughout the image area, while delivering smooth, creamy bokeh in out-of-focus areas. Two XA elements compensate for coma, field curvature, and astigmatism, that can be problems with wide-angle large-aperture optics. These elements also enable closer focusing distance and contribute to the compact and lightweight design. | Beautiful, natural-looking bokeh While the two XA elements effectively suppress onion ring bokeh, the 11-blade circular aperture maximizes the beauty of this large-aperture prime-lens, contributing to impressive images in which the subject stands out against a smoothly defocused foreground and background, as well as perfectly round points of defocused light. Conventional aperture blades have flat sides that create unappealing, polygonal-shaped defocused points of light. This lens overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result. |
