Step up to a new level of creativity with Sigma Lenses and discover more ways to photograph your world.The 28-105mm f2.8-4.0 Aspherical IF lens sets a new standard for all zooms.
Its unusually large maximum aperture is made possible by an extra-wide aspherical lens to provide higher optical performance in a number of ways, including effective anti-flare features and crisp-to-the-edge images.
An internal focusing mechanism allows the front of the lens to remain stationary and to easily accommodate specialty filters, such as polarizing filters.
Sigma's original 4-group zoom mechanism keeps size and weight to a minimum while fully correcting astigmatism and distortion.
Its wide range and convenience make it perfect for snapshots and great travel photos.
