Sony SEL50F18/B Specifications

SEL50F18/B
Key Features
Built-in Optical SteadyShot
The built-in Optical SteadyShot image stabilization system provides a 4-stop (approx.) shutter speed advantage, making it
significantly 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 effectively 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 affords an appearance that blends beautifully
with the graceful design of E-mount bodies, and the engraved focus ring offers 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 after 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
specific point, DMF facilitates fast, easy fine focus adjustments. This can be particularly useful for portraits in which depth of
field can be extremely shallow.
