Sigma 24-70mm F2.8 DG DN II Art Lens for Mirrorless Cameras, L-Mount, Support Entire Zoom Range Overview
Description
The SIGMA 24-70mm F2.8 DG DN II Art for L-Mount is a full frame standard zoom lens that covers everything from wide landscapes to tight portraits with a constant bright F2.8 aperture. It is part of the Art line, designed for high optical performance with sharp rendering across the zoom range, smooth bokeh from an 11 blade diaphragm and control that suits demanding hybrid photo and video workflows.
This second generation version improves portability and handling while adding pro features. It is about seven percent shorter and ten percent lighter than the previous model, yet it keeps a robust, dust and splash resistant structure, Nano Porous and Super Multi Layer Coatings, a new aperture ring with click and lock switches, two customizable AFL buttons and a high response linear actuator autofocus system for faster, quieter focusing.

- Travel, landscape and documentary shooting that benefits from a compact, weather resistant standard zoom.
- Hybrid video projects that use focus breathing control, quiet AF and manual aperture operation for smooth exposure changes.
