Key Features
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, are 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, eectively suppress
aberrations, achieving impressively high resolution that fully satises 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 dierences in refraction at dierent 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 aect 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 are and ghosting by suppressing internal
reections and maintaining clarity, even in dicult outdoor lighting conditions, for dynamic
range that achieves lifelike detail and gradation with advanced camera sensors. This precisely
dened 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 reection
suppression characteristic of the Nano AR Coating is superior to conventional anti-reective
coatings, providing a notable improvement in clarity, contrast, and overall image quality.
9-blade Circular Aperture
When changing your aperture to defocus the background, light sources appear blurred. This
‘bokeh’ eect of the blurred background is enhanced with the 9-blade circular aperture used
in this lens. Conventional aperture blades have at sides creating unappealing, polygonal-
shaped defocused points of light. α lenses overcome 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 magnication is ideal for portraits, telephoto macro, and more. Contributing
renements include ED glass elements and a oating focus mechanism to control aberration that
can be problematic in close-up applications.
