Lens

DSC-W650, WX50, WX70, TX66, TX200V, TX20, HX200V

For superior sharpness, excellent contrast and color accuracy, professional
photographers depend on Carl Zeiss

®

lenses. That’s because they can be relied

upon to consistently maintain the resolution, contrast, illumination and color of
photos — from the center all the way to the corners. These diverse lenses offer
wide angles up to 25mm equivalent, which make it easier to get better group
shots in tight confines and focal lengths up to 870mm equivalent on the HX200V
for great shots even from far away.

G Lens

DSC-W690, WX150, H90, HX10V, HX20V, HX30V

To help you get the best shots, Sony’s G Lens covers a wide focal length
range and provides exceptional contrast and sharpness. An excellent
example is the G Lens of the Cyber-shot

®

DSC-HX20V which covers a broad

range from 25mm equivalent wide-angle to 500mm equivalent telephoto.
Consisting of 12 elements in 9 groups, this lens includes 4 aspherical elements
and an extra-high refractive index element to minimize chromatic aberration.

Sony’s G Lens is also capable of very high zoom functionality. DSC-HX20V offers
a high optical zoom of 20x which is excellent for use at sporting events, wildlife,
distant landscape views and dramatic portrait shots.

The better the lens,

the better the picture.

Advanced Aspherical Element

DSC-W690, WX150, HX20V, HX30V

For 2012, Sony was able to double the optical zoom ratio in lenses that are as
much as 54% thinner than last year’s. It’s an incredible feat of optical engineering,
made possible by Sony’s Advanced Aspherical (AA) lens element. By controlling

chromatic aberration on the image plane, the AA element enables the lens to

be not only substantially thinner than last year, but also up to 37% smaller in

diameter. At its center, the AA element is just 0.3 mm thick (about 1/100 inch).

Molding and shaping the element requires extraordinary precision. And that’s
exactly what Sony achieves. The result? Maximum zoom in minimum size — with
no sacrifice in image performance!

Highlighted in green, Sony’s Advanced Aspherical element is the
secret behind higher zoom in a thinner camera.
