Formally referring to wide-angle, this lens is actually a hybrid between this class and medium focal lengths: its focal length range is 17 – 35 mm, and viewing angles are 107.3 ° — 63.4 °. Of the design features, we can distinguish an ultrasonic autofocus motor, as well as an 8-blade aperture (minimum value of 22). Available in modifications for Canon EF, Nikon F, Pentax K, Sigma SA and Sony/Minolta A mounts, standard type of matrix is full frame.

Everything is relative: interchangeable lenses for cameras from third-party manufacturersLenses from alternative brands: money down the drain or an increase in image quality?

Short description:

Fast wide-angle lens that provides an ultra-wide field of view up to 104°. SIGMA specialists managed to achieve a minimum focus distance of 27 cm at any focal length and a maximum magnification for macro shooting up to 1:4.5. The optical scheme of the lens includes one element of low dispersion (SLD, Special Low Dispersion) glass and two aspherical elements, which allows you to effectively deal with distortion and any kind of aberration. Modification 17-35mm F2.8-4 EX DG Aspherical HSM is equipped with an ultrasonic drive (HSM, Hyper-Sonic Motor), which provides fast and silent autofocus, while leaving the possibility of manual focus at any time.
