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.
