Sony SEL16F28 16mm f/2.8 Wide-Angle Lens for NEX Series Cameras

Description

Sony SEL16F28 16mm f/2. 8 Wide-Angle Lens for NEX Series
Cameras Landscapes, architecture, snapshots . this 24 mm equivalent (35mm full
frame format) E-mount prime lens can cover them all. Compact and extremely
lightweight, this lens will always be ready for action without being a burden
to carry. While a refined aluminum alloy exterior gives the lens a
sophisticated feel, a motor on the inside delivers smooth, quiet autofocus and
aperture operation that contributes to high-quality movies as well as stills.
When 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. Aspherical 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. The distance
encoder plays an integral part in ADI flash metering, which delivers high
precision flash metering that is unaffected by the reflectance of subjects or
backgrounds. The distance encoder is a lens component that directly detects
the position of the focusing mechanism, and sends a signal to the CPU in order
to measure distance to the subject. During flash photography, this data is
very useful in calculating how much flash output is appropriate to the scene.
Only 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. 2012 Sony Electronics All rights reserved.
