Sony SEL-50F18 User manual

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.
