Built-in Optical SteadyShot
TM
 image stabilization
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.
