SIGMA 28-70MM F2.8 AF DG DN L-MOUNT LENS

The contemporary 28-70mm f/2.8 DG DN lens for Leica L mount by Sigma is a versatile wide-angle to portrait-length zoom characterized by its constant f/2.8 maximum aperture. The design is suitable for working in available lighting conditions while offering greater control over depth of field. Lighter and more compact than similar 24-70mm lenses, its optical design incorporates two FLD and two SLD low dispersion elements, as well as three aspherical elements that reduce a variety of aberrations to achieve great sharpness, enhanced clarity, and improved color accuracy.

It features a single lightweight focusing element, which keeps the AF unit small. This, along with a quiet and fast stepping motor, allows for responsive and nearly silent autofocus performance, making it an ideal combination for filmmakers seeking a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal or other accessories.

Each optical surface features Super Multi-Layer and Nano Porous coatings to enhance contrast and color reproduction by suppressing flare and ghosting for optimal light transmission, and an additional water- and oil-repellent coating on the front optics helps keep the lens free of smudges and droplets. The weather-sealed design benefits working in harsh environmental conditions, and a nine-blade rounded diaphragm contributes to a pleasing bokeh quality when using wider apertures.

• Standard zoom for L-mount mirrorless and full-frame cameras

• 42 to 105mm equivalent focal length when used on an APS-C camera

• Constant f/2.8 maximum aperture for low-light use and depth of field control

• Two F Low Dispersion (FLD) elements and two Special Low Dispersion (SLD) elements reduce chromatic aberrations and color fringing.

• Three aspherical elements control spherical aberrations and distortion.

• Both Super Multi-Layer and Nano Porous coatings minimize lens flare and ghosting and produce images with rich contrast and neutral colors.

• The integrated stepping motor and optimized AF algorithm provide fast and quiet autofocus

• Minimum focus distance at 28mm: 19.05 cm, magnification of 1:3.3

• Minimum focus distance at 70mm: 38.1 cm, magnification of 1:4.6

• Nine-blade rounded diaphragm for a pleasing bokeh quality

• Brass bayonet for greater mounting precision and rigidity.

• Rubber sealing for dust and splash resistance.
