The advanced optical design-including a spherical and ?AA? (advanced spherical) lens elements combined with renowned ZEISS T coating-deliver outstanding image resolution and suppresses reflections for superior contrast clarity. ZEISS T anti-reflective coating minimises flareFrom the ManufacturerDistagon T* FE 35mm F1.4 ZA Full-frame E-mount Prime LensThe 35mm focal length makes the Distagon T* FE 35mm F1.4 ZA an excellent choice for a wide range of photography, from snapshots and landscapes to indoor portraits and night scenes - producing beautiful bokeh through its bright 9- blade F1.4 aperture. The advanced optical design - including aspherical and ?AA? (advanced spherical) lens elements combined with renowned ZEISS T* coating - deliver outstanding image resolution and suppresses reflections for superior contrast clarity.Additional FeaturesUnmatched ZEISS T* (T-star) coatingCoated optics were pioneered by Carl Zeiss - and this superb lens features the ZEISS T* (T-Star) coating that virtually eliminates lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces. The T* coating contributes to outstanding image quality, with high contrast and uniformly excellent resolution right out to the image edges. Not simply applied to any lens - the T* symbol only appears on multi-element lenses in which the required performance has been achieved throughout the entire optical path, therefore guaranteeing the highest quality.Circular 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. ? 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.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.Responsive aperture ringA responsive aperture ring offers positive action that will satisfy professional photographers and moviemakers alike. The aperture ring click stops can be switched on or off as required. ?Off? is the preferred setting for moviemaking since it results in the least aperture operation noise. When ?On? the ring provides tactile feedback that is useful when shooting stills. 2015 Sony Electronics Inc. All rights reserved.
