Product Description
-------------------
Sony SEL16F28 16mm f/2. 8 Wide-Angle Lens for NEX Series Cameras
Landscapes, architecture, snaps . this 24 mm equivalent (35mm
full frame format) E- 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.

Circular Aperture
