Built-in Optical SteadyShotTM image stabilization

The built-in Optical SteadyShot image stabilization system provides a 4-stop (approx.) shutter

speed advantage, making it signicantly easier to achieve crisp, blur-free images and video.

Large F1.8 aperture

The SEL50F18 has an innovative optical design to achieve clear, high-quality images by

eectively minimizing distortion and chromatic aberration. Moreover, the large maximum

aperture of this lens with its circular aperture design, can produce beautiful, creamily defocused

backgrounds.

Smooth and quiet high-speed focusing

Lens operation is fast but at the same time smooth and quiet, minimizing noise and image

jitter when shooting movies. A linear motor used for focus drive contributes to low-noise focus

operation, while a stepping motor built into the lens, technology inherited from Sony's professional

camcorders, results in smooth, quiet aperture actuation ideal for movie shooting.

Compact and lightweight

The SEL50F18 is remarkably compact and lightweight for a large-aperture mid-range telephoto

lens (50mm focal length/75mm equivalent in 35mm format). It is convenient to carry around for

general photography, and particularly well suited to shooting portraits. The elegant aluminum

alloy exterior of this lens aords an appearance that blends beautifully with the graceful design

of E-mount bodies, and the engraved focus ring oers sophisticated appearance as well as

superior grip and operating feel.

Direct Manual Focus (DMF)

Direct Manual Focus (DMF) allows the user to go directly to manual focusing aer autofocus

lock-on without having to switch modes. In cases where autofocus has trouble locking onto the

subject, or when the user wants to focus at a specic point, DMF facilitates fast, easy ne focus

adjustments. This can be particularly useful for portraits in which depth of eld can be extremely

shallow.
