Full details
The SIGMA 28-105mm F2.8 DG DN Art lens is a high-performance standard zoom designed for Sony E-mount full-frame mirrorless photographers who demand both versatility and professional-grade image quality. By offering a constant F2.8 aperture across an extended 28-105mm zoom range, it eliminates the need to switch lenses during fast-paced shoots, though its robust professional-grade glass results in a heavier build than compact consumer alternatives.

Setup, Compatibility & Care
This lens is designed specifically for Sony E-mount full-frame mirrorless cameras. To set up, align the white mounting mark on the lens with the camera body and rotate clockwise until it clicks. Ensure the firmware on your Sony camera is up to date to maintain compatibility with the HLA motor. For maintenance, use a lens blower to remove dust from the glass before wiping with a clean microfiber cloth. While the lens is weather-resistant, avoid direct contact with water and always use the included lens hood to protect the front element from impact and stray light.
