Fast and Portable Wide-Angle Combining a favored wide-angle focal length with an especially bright design, the FE 24mm f/1.4 GM from Sony is a fast, versatile lens well-suited to landscape, astrophotography, and street shooting applications. Its wide-but-usable perspective is complemented by the f/1.4 maximum aperture and the lens is also distinguished by a sleek, portable profile for all-day shooting. G Master Optical Performance Sample Photo As part of Sony's esteemed G Master series, this lens is designed to achieve notably high resolution and sharpness through the correction of a wide variety of spherical and chromatic aberrations. Notably fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also affords increased control over depth of field. Rounded 11-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques. Two XA elements are incorporated into the optical design, which features superior surface precision for effective control over astigmatism, field curvature, coma, and other spherical aberrations. Three extra-low dispersion elements are featured in the lens design and help to reduce chromatic aberrations and color fringing for improved clarity and color neutrality. Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast in strong lighting conditions. Responsive AF and Intuitive Handling Direct Drive Super Sonic wave Motor AF system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control. A focus hold button is present on the lens barrel for intuitive tactile control and rapid access to select settings. Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications. Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures. Fluorine-coated front element resists dust, moisture, and fingerprints and is easy to clean
