Product Description
-------------------
High performance and a compact design make the SEL-35F18 an
ideal “second lens” that is easy to carry around when capturing
the action. It’s ideal for a wide variety of photos, including
snaps while strolling, night s (thanks to the bright
maximum aperture) and portraits with superb background/foreground
blur. Designed for use with: Hasselblad Lunar Sony PXW-FS5 Sony

PXW-FS7 Sony PXW-FS7M2 Sony QX1 High performance and a compact
design make the SEL-35F18 an ideal “second lens” that is easy to
carry around when capturing the action. It’s ideal for a wide
variety of photos, including snaps while strolling, night
s (thanks to the bright maximum aperture) and portraits with
superb background/foreground blur. 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. 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 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.
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. 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

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
