Description

Sony SELP1650 16-50mm Power Zoom Lens
Product Overview
Compact and lightweight design for excellent portability
thanks to retract-ability down to a mere 29.9 mm From the Manufacturer E PZ
16-50mm F3.5-5.6 OSS Power Zoom Lens This 16-50mm retractable zoom lens is
super compact and easy to carry and the ideal lens for traveling and other
scenarios that require a lightweight, compact camera and lens combo.
Technology Circular Aperture 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. ED (Extra-low Dispersion) glass As
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 elements 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. Distance encoder 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. Lens-based optical image
stabilization Gyro 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 Features Internal focusing 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. SELP1650 not recommended for use with NEX-3, NEX-5, NEX-C3
