Sony has taken the wraps off of its new full-frame 24mm F1.4 G Master prime lens. Despite that fast maximum aperture, Sony has created a remarkably small and light lens compared to its peers, with a weight of just 445 grams
The 24mm F1.4 GM has a total of 13 elements, including two XA (extreme aspherical) which significantly reduce coma, and three ED elements. Sony's Nano AR coating reduces flare and ghosting, and so far, we're impressed by the lack of distracting flare artifacts and high contrast images even when shooting into the sun. 11 aperture blades yield smooth bokeh and circular out-of-focus highlights even when you stop down to F2.8, as well as 22-blade sharp sunbursts if you stop down further with bright, pinpoint light sources.
The focus is driven by a new, evolved Direct Drive SSM motor that deliveries 'approximately three times greater thrust' than the previous system, but with high positional accuracy, according to Sony.
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. Additionally, these lenses feature robust and intuitive-to-handle physical designs to benefit both photography and cine applications.
Versatile wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras, however, can also be used on APS-C models where it provides a 36mm equivalent focal length.
Notably fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also affords increased control over depth of field.
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 colour fringing for improved clarity and colour neutrality.
A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and colour rendering in strong lighting conditions.
A Direct Drive Super Sonic wave Motor AF system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to a 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.
Rounded 11-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
