High-Precision Build Quality The Sigma 105mm F1.4 DG HSM Art lens boasts superb build quality. The outer barrel is made from Thermally Stable Composite (TSC), which is strong, lightweight, and has a thermal expansion rate similar to aluminium, ensuring consistent performance across different temperatures. The lens features a rubberised focus ring for easy operation and an internal focusing mechanism, maintaining a constant lens length during use. Versatile and Robust Design Equipped with a tripod foot (TS-111) featuring an Acra Swiss dovetail, this lens can be easily attached to most tripod heads without a plate. The collar is removable for more comfortable hand-held shooting. A robust lens hood with a rubberised ring reduces flare and ghosting in bright sunlight and protects the front element from damage. Outstanding Optical Quality Across the Frame The Sigma 105mm F1.4 DG HSM Art lens delivers exceptional optical quality, even wide open at F1.4. Its advanced design ensures sharp detail from the center to the corners, with minimal chromatic aberration, flare, distortion, and vignetting. The Super Multi-Layer Coating further enhances image quality by reducing flare and ghosting, even in challenging lighting conditions. High Contrast and Rich Colours The lens’s excellent control of flare and ghosting results in high contrast and richly saturated images, with strong blacks and vibrant colours.
