Product description

• Standard zoom lens is designed for APS-C-format Sigma SA-mount cameras and provides a 25.5-75mm equivalent focal length range.

• Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.

• Two F Low Dispersion (FLD) elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.

• Three aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.

• Super Multi-Layer Coating has been applied to individual elements to minimize flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.

• Hyper Sonic Motor (HSM), along with an internal focusing design, realizes quick and quiet autofocus performance as well as full-time manual focus override.

• Minimum focusing distance of 11" and a 1:5 maximum magnification ratio benefits working with close-up subjects.

• Optical Stabilizer system minimizes the appearance of camera shake to benefit making sharper imagery when shooting handheld.

• Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
