The Sigma 24-70mm f/2.8 DG DN II Art 

Core Improvements

• Faster Autofocus: Now uses the HLA (High-response Linear Actuator) motor, providing much faster and more accurate tracking for both high-speed photography and video.
• Reduced Weight: It is roughly 10% lighter than the original version (approx. 745g), making it more balanced on modern mirrorless bodies.
• Tactile Controls: It adds a dedicated Aperture Ring with a de-click switch (ideal for video) and an Iris Lock switch. It also features two customizable AFL buttons.
• Better Close-Ups: The minimum focusing distance is improved to 17cm at the wide end, allowing for impressive wide-angle macro shots.
