Sony Alpha E-Mount FE 24-105mm f/4.0 G OSS Zoom Lens
A compact, lightweight, and comprehensive zoom.
With a versatile 24mm to 105mm range, the Sony Alpha E-Mount FE 24-105mm F4 G OSS Zoom Lens brings outstanding G Lens excellence to a variety of still and movie applications. Weighing in at only approximately 23.4 oz (663g), makes it the lightest lens in its class. When combined with one of Sony's Alpha E-mount bodies, it gives photographers and videographers a far more mobile, manageable camera system that greatly increases their shooting flexibility.
This high-performance lens lets you shoot a wide range of subjects and situations. With a minimum focus distance of 1.25 ft (0.38 m) and built-in optical image stabilization to make it easier to produce sharp, blur-free images when shooting handheld. Advanced Aspherical (AA) elements, ED (Extra low dispersion) glass elements and Nano AR Coating contribute to control ghosting, flare and aberration. A 9-blade circular aperture and constant F4 aperture deliver beautiful bokeh.
Further adding to its versatility, the SEL24105G also features Sony's DDSSM (Direct Drive SSM) system, capable of rapid positioning focus groups with high accuracy and minimal noise, a customizable focus hold button, a dust and moisture resistant design and a fluorine coating on the front element to help minimize dust, water, oil and other contaminants.
24mm to 105mm constant F4 aperture:
24mm wide angle to 105mm mid-telephoto zoom with spectacular corner-to-corner resolution and high optical performance deliver spectacular overall rendering that is consistent with the G Lens brand. Advanced Aspherical (AA) elements, ED (Extra low dispersion) glass elements and Nano AR Coating contribute to control ghosting, flare and aberration. A 9-blade circular aperture and constant F4 aperture deliver beautiful bokeh.
Advanced Aspherical optical design:
Four aspherical elements, including two advanced aspherical elements, effectively suppress aberrations, achieving impressively high resolution that fully satisfies expectations for the G Lens brand. Spherical aberration is a slight misalignment of the light rays projected on the image plane, which is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped "aspherical" elements in this lens restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and ultra-wide angles. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight.
ED (Extra low dispersion):
Three ED (Extra-low Dispersion) glass elements control chromatic aberration for excellent sharpness from image center to periphery. ED glass elements correct for axial chromatic aberration and chromatic aberration, which affect resolution and bokeh, while leaving precisely rendered edges with no fringing or unnatural coloration.
Nano AR Coating:
Sony's original Nano AR Coating technology minimizes flare and ghosting by suppressing internal reflections and maintaining clarity, even in difficult outdoor lighting conditions, 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, 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.
Fluorine coated front element:
The lens's front element features a fluorine coating that helps to prevent fingerprints on the lens and stop dirt from sticking, and makes it easier to wipe away any dirt and fingerprints that do appear on the lens surface.
9-blade Circular Aperture:
When changing your aperture to defocus the background, light sources appear blurred. This 'bokeh' effect of the blurred background is enhanced with the 9-blade circular aperture used in this lens. Conventional aperture blades have flat sides creating unappealing, polygonal-shaped defocused points of light. This lens overcomes this problem through a 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.
Class-leading close-up performance:
Class-leading close-up performance with a minimum focusing distance of 14.9" and 0.31x maximum magnification is ideal for portraits, telephoto macro, and more. Contributing refinements include ED glass elements and a floating focus mechanism to control aberration that can be problematic in close-up applications.
Constant F4 aperture:
Constant F4 max aperture maintains exposure and depth of field regardless of the focal range to which you zoom. 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.
Internal Focus maintains lens dimensions:
Only the middle groups of the optical system move to achieve focus, so the overall length of the lens does not change while focusing. This is especially useful when using the lens for video with a matte box.
Direct Drive Super Sonic Wave Motor:
High-resolution cameras demand absolute focus precision. A floating mechanism driven by a DDSSM (Direct Drive Super Sonic Wave Motor) actuator maintains outstanding resolution from infinity to close focus for both stills and movies. DDSSM has the capability to position the large, heavy optical assemblies required by large-aperture lenses with pinpoint precision, offering accurate, fast and quiet autofocus. Manual focus response is natural, intuitive and precise with the DDSSM system.
Optical Image Stabilization:
Optical SteadyShot Image Stabilization keeps your image stable even when your hands aren't. By compensating for the minor hand motions that can cause blurring and distortion, Optical SteadyShot ensures brilliant photographic results -- even at high zooms.
Instant auto/manual focus selection:
Instantly switch between auto and manual focus via an AF/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.
Focus hold button:
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, custom functions include: Grid Lines, Eye AF, AF On, Aperture Preview, Shot Result Preview or Bright Monitoring.
Dust and moisture resistant for robust reliability:
Sony's standard lens sealing is augmented by a lens mount seal that maximizes resistance to dust and moisture for reliable operation in challenging environmental conditions. Additional details, like rubberized rings that are easy to operate in low temperatures, a customizable focus hold button and a hood lock button, all add up to professional control and convenience.
Impeccable Sony G Lens design emphasizes a graceful balance between high resolution and gorgeous background bokeh that can enhance the artist's vision.
