The Canon EF-mount 105mm f/2.8 EX DG OS HSM Macro from Sigma is a short-telephoto prime characterized by its ability to achieve a 1:1, life-size magnification along with a 1' minimum focusing distance for macro applications. The optical design employs two SLD elements to virtually eliminate chromatic aberrations and color fringing throughout the focusing range for improved clarity and color rendering. A Hyper Sonic Motor affords quick and quiet autofocus performance while an Optical Stabilizer minimizes the appearance of camera shake for sharper handheld shooting. Bright f/2.8 maximum aperture is well-suited for working in available light conditions and also provides greater control over the focus position when using shallow depth of field techniques. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. Optical Stabilizer system minimizes the appearance of camera shake to benefit making sharper imagery when shooting handheld.
