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. α 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.
Nano AR coating suppresses reflections, flare and ghosting
Sony’s original Nano AR Coating technology minimizes flare and ghosting, for dynamic range that achieves lifelike detail and gradation with advanced camera sensors. This precisely defined regular nano-structure allows accurate light transmission, contributing to high-quality images, even more so than with lenses that use coatings with an irregular nano-structure. The reflection suppression characteristic of the Nano AR Coating is superior to conventional anti-reflective coatings, providing a notable improvement in clarity, contrast, and overall image quality.
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.
Manual aperture ring w/ selectable on/off click for stills or movie
A responsive manual aperture ring offers positive action that will satisfy professional photographers and moviemakers alike. The aperture ring click stops can be switched on or off as required. “Off” is the preferred setting for moviemaking since it results in the least aperture operation noise. When “On” the ring provides tactile feedback that is useful when shooting stills.
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.
Dust and moisture resistant for robust reliability
The dust and moisture resistance design makes this lens appropriate for heavy-duty outdoor use, especially when combined with a camera that employs weather resistant measures.
Astrophotography Sagittal flare suppression
Sagittal flare is a phenomenon that results in an unnatural spreading of point light sources that appears somewhat like a bird spreading its wings and becomes more pronounced towards the image periphery. It is most common in large-aperture lenses. The 24mm F1.4 GM incorporates a new optical design, including two XA lens elements, to effectively suppress and correct for sagittal flare, making this lens ideal for night sky and astrophotography.
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.
Linear Response MF
Linear Response MF realizes precise manual focus control, closely equivalent to mechanical manual focus, which enables linear focus transition to ring rotation angle for repeatable and accurate manual focus that is especially desirable for MF control during video capture.
Close-up, wide angle shooting
Get a unique perspective through close-up, wide angle shooting. The combination of high close-up capability with a minimum focusing distance of 0.79ft. (0.24m), a max. magnification of 0.17x and wide angle characteristic produces unique expression with dramatic perspectives and beautiful background bokeh.
