Sony Lente de zoom estándar intercambiable F3.5-5.6 FE OSS de 1.102-2.756 in

Descripción
Reseña del editor Este asequible objetivo zoom de alto rendimiento no solo es compacto y ligero, sino que también ha sido diseñado específicamente para sacar lo mejor de los cuerpos de montura E de fotograma completo de la serie a7. El rango de zoom se extiende de 1.102 in a 2.756 in, proporcionando un fácil acceso a los ángulos de visión más utilizados y, gracias a un diseño óptico avanzado, el cambio en la longitud total de la lente durante el zoom es mínimo From the Manufacturer FE 28-70mm F3.5-5.6 OSS Full-frame Zoom LensThis affordable mid-range zoom lens for 35mm full frame format cameras combines high optical performance with compact, lightweight convenience. The FE 28-70mm is ideal for a wide range of subjects, and is dust and moisture resistant for consistent reliability. Optical SteadyShot image stabilization included.TechnologyCircular ApertureWhen changing your aperture to defocus the background, the light sources appear blurred. This ‘bokeh’ effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses 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.ED (Extra-low Dispersion) glassAs focal lengths get longer, lenses built with conventional optical glass have difficulties with chromatic aberration, and as a result images suffer from lower contrast, lower color quality, and lower resolution. ED glass dramatically reduces chromatic aberration at telephoto ranges, and provides superior contrast across the entire image, even at large aperture settings. Super ED glass provides enhanced compensation for chromatic aberration.Aspherical lens elementsAspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped “aspherical” elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight. Advanced Aspherical (AA) elements are an evolved variant, featuring an extremely high thickness ratio between the center and periphery. AA elements are exceedingly difficult to produce, relying on the most advanced molding technology to consistently and precisely achieve the required shape and surface accuracy, resulting in significantly improved image accuracy and quality.Lens-based optical image stabilizationGyro sensors built into the lens detect even the slightest movement, and the stabilization lens is precisely shifted to counteract any image blur that might occur. The use of precision, quiet linear motors and technology inherited from high-end Sony professional camcorders results in exceptionally quiet, effective image stabilization that contributes to high-quality movies as well as stills.Additional FeaturesInternal focusingOnly the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change. Other important benefits include fast autofocusing and a short minimum focusing distance. Also, the filter thread at the front of the lens does not rotate, which is convenient if you’re using a polarizing filter.2013 Sony Electronics Inc. All rights reserved.
