Ultra-wide 20 mm perspectives, superb resolution from F1.8
乐彩33是不是合法网站two aa (advanced aspherical) elements in an innovative optical design minimize aberration for outstanding corner-to-corner resolution right from the lens's widest f1.8 aperture.
Compact and lightweight for enhanced mobility and handling
乐彩33是不是合法网站an advanced optical design that includes two aa elements is supported by a refined mechanical system in a g lens that weighs just 13.2 oz (373 g). small size and light weight enhance mobility when used with compact e-mount bodies, and make up a well-balanced system that is ideal for use on gimbals or accessory grips. the fe 20 mm f1.8 g is a versatile lens for a wide variety of still and movie shooting situations.
Smooth, natural-looking bokeh
in addition to precise control of spherical aberration—which has significant influence on bokeh quality—the fe 20 mm f1.8 g has a 9-blade circular aperture that contributes to smooth, creamy bokeh and natural-looking highlights that are hallmarks of the g lens series.
Realistically rendered point sources
乐彩33是不是合法网站two aa (advanced aspherical) elements and three ed (extra-low dispersion) glass elements are employed to minimize sagittal flare so that point light sources are reproduced accurately and without color smearing.
XD Linear Motors maximize AF speed, precision, and tracking
乐彩33是不是合法网站two xd (extreme dynamic) linear motors easily keep up with the high-speed capabilities of today's most advanced camera bodies, taking advantage of their full autofocus speed, precision, and tracking potential to capture the most dynamic subjects. new control algorithms make it possible to drive the lens's large focus group smoothly and without delays for responsive, silent, low-vibration autofocus.
Excellent close-up performance, even for selfies
乐彩33是不是合法网站in addition to the fact that 20 mm is a great focal length for selfies, this lens has a minimum focusing distance of just 0.63 ft (0.19 m) when used in af mode, and an even closer 0.59 ft (0.18 m) minimum focusing distance when focused manually. it is an excellent choice for gimbal/grip mounting, whether shooting selfies or other subjects.
Smooth operation and high reliability in a compact lens
A focus hold button, focus mode switch, aperture ring and other controls are designed and positioned for easy operation and a smooth workflow. Alternative functions that support the user's individual shooting needs can be assigned to the focus hold button via camera body menu settings. The front lens element is fluorine-coated to repel water and grime, and the lens' dust- and moisture-resistant design provides the reliability needed for outdoor use in challenging conditions.
Impeccable Sony G Lens design emphasizes a graceful balance between high resolution and gorgeous background bokeh that can enhance the artist's vision.
