Sigma 24mm f/1.4
Sigma 24mm f/1.4 DG HSM Lens is a member of the highly regarded Art line of Sigma’s Global Vision Series. And it is characterized by its advanced optical construction and robust physical design. The combination of three “F” Low Dispersion (FLD) elements. And four Special Low Dispersion elements help to achieve a marked reduction in chromatic aberrations. While a pair of aspherical elements, with one positioned in the rear of the lens, minimize a variety of additional distortions and aberrations.
Complementing the optical performance is an equally adept Hyper Sonic Motor. Which provides fast, smooth, and near-silent autofocus performance. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control. Nine rounded diaphragm blades contribute to pleasing out-of-focus quality when working with shallow depth of field techniques. And the lens is also compatible with the optional Sigma USB Dock for fine-tuned control over focusing parameters and other lens characteristics.
The prime 24mm focal length offers a versatile wide-angle perspective. When used on full-frame sensors, making it ideal for landscape, nature, interior, and architectural photography. When used with an APS-C-format sensor, the lens offers a 38.4mm equivalent focal length.
A pair of aspherical elements, with one in the rear of the optical design. Correct for sagittal coma flare, distortion, and axial chromatic aberration. While also enabling full use of the fast f/1.4 maximum aperture with maintained peripheral brightness and sharpness.
The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.
This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
