Description
The circular aperture also features a total of 11 blades, allowing the lens to produce perfectly round out-of-focus lights and smoother bokeh. Aside from supporting hybrid autofocus with both contrast and focal-plane phase detection AF, the lens has a Direct Drive Super Sonic Motor (DDSSM) system that provides quick, silent, and high-precision AF performance.
Three extra-low dispersion (ED) and two extreme aspherical (XA) lens elements significantly reduce chromatic and spherical aberrations for enhanced image sharpness and clarity. The glass elements are also Nano AR-coated to control lens flaring and ghosting, thus increasing image contrast and color fidelity even when shooting in harshly lit environments.
Compact G Master wide prime lens w/ stunning wide-open resolution
The FE 24mm F1.4 GM realizes consistently high resolution across the entire frame and delivers soft and natural bokeh – a signature feature of Sony’s G Master lens series. It also boasts a new optical design comprised of 10 groups with 13 elements, including two XA (extreme aspherical) and three ED (Extra-low Dispersion) elements. The incorporation of two XA elements ensures that point light sources can be accurately reproduced, making the FE 24mm F1.4 GM a compelling proposition for astrophotography. For impressive clarity, Sony’s unique Nano AR Coating is applied to reduce lens flare and ghosting, even in landscape shots where the position of the sun can be problematic with a normal lens.
F1.4 max aperture
The F1.4 max aperture maintains exposure and depth of field, allowing you to isolate your subject from the foreground and background with amazing light gathering capabilities when shooting wide open. When changing your aperture to defocus the background, the areas out of the focal plane appear blurred. This ‘bokeh’ effect of the blurred background is enhanced with circular aperture blades used in this lens.
11-blade circular aperture contributes to gorgeous bokeh
The 11-blade circular aperture maximizes the beauty of this large-aperture prime-lens, contributing to impressive images in which the subject stands out against a smoothly defocused foreground and background, as well as perfectly round points of defocused light. Conventional aperture blades have flat sides that create unappealing, polygonal-shaped defocused points of light. a lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.
Direct Drive SSM (DDSSM) for fast, quiet, precise focusing
The 24mm F1.4 GM lens supports hybrid autofocus for both contrast and focal-plane phase detection AF. It has a high-precision Direct Drive Super Sonic Motor (DDSSM) system that ensures exceptionally fast, quiet and accurate AF performance. The precision internal focus mechanism aids in AF speed by moving only the middle groups of the optical system and effectively minimizing focus breathing, while keeping the lens size compact and lightweight. In addition to being the ideal wide prime lens for stills, it is also exceptionally suited for video with a linear motor that takes on the vital role of ‘wobbling’ to providing high-speed actuation for the contrast AF detection system, for smooth, continuous AF.
Two XA (Extreme Aspherical) lens element
The 24mm F1.4 GM employs two XA (Extreme Aspherical) lens element, one of which is the front lens. This large-diameter front XA lens element features a new optical design, maximizing the advantages of the short mirrorless camera flange distance, and effectively suppresses various aberrations, especially the peripheral area in the frame and sagittal flare. Two XA elements compensate for coma, field curvature, and astigmatism that can be problems with wide-angle large-aperture optics. This also contributes to the compact and lightweight design.
Three ED (Extra-low dispersion) glass elements
Three ED (Extra-low Dispersion) glass elements take axial chromatic aberration and chromatic aberration due to differences in magnification out of the picture, maximizing resolution and bokeh while leaving precisely rendered edges with no fringing or unnatural coloration, while significantly reducing flare and ghosting.
Compact, lightweight design
This remarkably compact and lightweight lens weighs in at only 15.7oz (445g) with smallest in class dimensions of 3″ (75.4mm) diameter and 3-3/4″ (92.4mm) in length. It’s compact, lightweight design enhances portability and mobility thanks to the combination of optical design utilizing two XA elements and the newly developed DDSSM (Direct Drive SSM) AF system.
Focus hold button, programmable for multiple functions
The focus hold button not only performs its primary function to lock focus when recomposing, but can be customized to a number of other functions depending on your needs. In addition to Focus Hold, these custom functions include: Eye AF, AF On, Aperture Preview, Shot Result Preview or Bright Monitoring.
Instant auto/manual focus selection
Instantly and quickly switch between auto and manual focus via an AM/MF switch on the side of the lens. This makes operation faster and easier as you let the camera and lens focus for you, or decide to take control and manually focus on the precise point you chose.
