More details:

• MFL (Manual Focus Lock) Switch - A switch to lock the manual focus at a desired position. Prevents focus shift caused by unintentional operation of the focus ring. This is useful for long-time exposure photography, etc., where the focus is fixed.
• Lens Heater Retainer - Steps around the front and lens heater retainers prevent the lens heater from protruding into the front of the Leica and Sony lens and causing vignetting on the periphery of the screen.
• Rear filter Holder - A rear filter holder is provided as standard equipment at the Sigma 14mm 1.4 lens mount for attaching a sheet-type rear filter. A lock mechanism is also provided to prevent the filter from falling out.
• Special front cap with locking mechanism and filter slots - Includes a cover-type front cap with a locking mechanism. It also has a newly developed filter slot that can hold two rear filters depending on the application. The cap is specially designed for the Sigma Art lens to protect the sheet filters from scratches and dirt while ensuring that they are not mistakenly taken out or forgotten.
• Inner focus system - To increase stability, this Sigma Art 1.4 lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
• HLA (High-response Linear Actuator) - HLA is SIGMA’s proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.
• Abundant functions and accessories to support starscape photography - The Sigma DG DN Art lens is equipped with a wealth of features to support starscape photography. This fully backs up the fun of starscape photography.
• Tripod Socket - Includes a detachable tripod mount compatible with Arca-Swiss type. The Sigma 1.4 lens can be mounted on a tripod in a more stable condition, as it is heavier on the front side. The shape is designed to prevent interference even when using the lens heater.
