Dynamic perspectives in an ultra wide-angle zoom
With a zoom range extending from 12mm to 24mm, the ultra wide-angle FE 12-24mm F4 G zoom offers the widest perspectives in the full-frame E-mount lens lineup. Optical aberrations that commonly detract from the performance of wide-angle designs have been effectively controlled, achieving excellent resolution throughout the image area. Despite its impressive performance, this lens is remarkably lightweight, compact, and mobile, offering quality and capabilities that will satisfy professionals' and enthusiasts’ needs for wider fields of view when photographing landscapes, architecture, and more.
Aspherical lens elements
Four aspherical elements in a new optical design effectively suppress aberrations that commonly occur in wide-angle lenses, 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. This 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 restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and ultra-wide angles, and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight.
Constant F4 max 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.
7-blade circular aperture contributes to gorgeous bokeh
When changing your aperture to defocus the background, light sources appear blurred. This ‘bokeh’ effect of the blurred background is enhanced with the 7-blade circular aperture used in this lens. Conventional aperture blades have flat sides creating unappealing, polygonal-shaped defocused points of light. a 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.
Direct Drive Supersonic Wave Motor (DDSSM)
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 and intuitive with the DDSSM system.
