Sony SEL20F28 Manuel utilisateur

Superior Image Quality

Three aspherical lens elements correct distortions and aberrations. In particular, image quality in peripheral areas has

been dramatically improved compared to previous lenses. The high resolution and excellent contrast assures richly

detailed images free of distortion, making the lens an outstanding choice for a wide range of subjects such as casual

snapshots to majestic landscapes.

Compact length

Measuring a mere 13/16 inches (20.4mm) the lens is 2mm shorter than the SEL16F28

High Quality Exterior

The aluminum alloy lens barrel is inlaid into a molded-plastic component for a lightweight yet durable construction and

features beautiful laser engraving of the product name and focal length for a stylish nish. The control ring allows for easy

operation while the lens exudes a stylish appeal.

Circular Aperture

The SEL20F28 features seven aperture blades that form a near circle. This result in a pleasing defocused circular eect on

the background of your image when the aperture is set wide open. The same type of internal stepping motor used for the

focus drive is used for aperture actuation as well, that result in a smooth, low-noise aperture operation ideally suited to

movie shooting.

Handy Focal Length

With a 20mm focal length (35mm equivalent 30mm) and a bright maximum aperture of F2.8, the SEL20F28 is ideal for a

variety of subjects from landscapes, interiors to casual snapshots.
