KeyFeatures. RF-Mount Lens/APS-C Format 29-80mm (35mm Equivalent) Aperture Range: f/2.8 to f/22 Minimum Focusing Distance: 4.8″ Three Aspherical Elements Special Low Dispersion Element Rounded 7-Blade Diaphragm Dust- and Splash-Proof Design Includes LH582-02 Lens Hood Standard zoom lens is designed for APS-C-format Canon RF-mount cameras and provides a 35mm equivalent focal length range of 29-80mm. Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques. Three high-precision glass-molded aspherical elements are used to help limit distortion and spherical aberrations and contribute to greater overall sharpness and accurate rendering. Special Low Dispersion (SLD) element reduces chromatic aberrations and color fringing. Super Multi-Layer Coating minimizes flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions. In-camera aberration correction further eliminates optical imperfections such as distortion and vignetting. Stepping motor with nearly silent autofocus that makes it perfectly suited to a range of photographic applications, including shooting in quiet environments, recording videos, and capturing fast-moving subjects. Minimum focusing distance of 4.8″ and a 1:2.8 maximum magnification ratio benefits working with close-up subjects. Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
