Inherits the development philosophy 
behind the SIGMA CINE LENS

High-end cine lenses used by professional filmmakers are required to have a consistent characteristic over the entire sensor at a high level, because these lenses are used to film a subject moving freely on the screen or while panning or tilting the camera. This represents exactly the concept of the Art Line; “optical performance comes first”, and the high-end cine lenses need to be designed with this idea. The SIGMA 40mm F1.4 DG HSM | Art is SIGMA’s first lens developed originally to live up to the sought-after angle of view and performance standard for a cine lens. This new perspective to ensure the quality of professional equipment for visual production empowers it to breakthrough also as an interchangeable photographic lens.  

Optical performance that meets the requirements
of high-end cine lenses

This lens effectively arranges three FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements to correct axial chromatic aberration and magnification chromatic aberration to the limit. A sharp image is formed on the focal plane with the maximum aperture and contrast with the soft bokeh in the out of focus area highlights the solidity of a subject. With a distortion of 1% or below and a sagittal coma flare corrected to the limit, it demonstrates a consistent optical characteristic over the entire sensor. This is the ultimate large-diameter standard lens that has both 8K-compatible resolution and beautiful bokeh.

Designed to meet all shooting conditions

The water- and oil-repellent coating on the front lens element, together with the dust- and splash-proof structure, ensures excellent performance even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.

• 
  water- and oil-repellent coating

  water- and oil-repellent coating Forefront and rear lenses incorporate a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.

• 
  dust- and splash-proof structure

  This lens features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather.

• 
  High-speed AF

  The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.

• 
  Hood with lock

  Features a hood with lock to prevent dropping the hood.

• Manual override (MO)

  Manual override (MO) capable of switching two full-time manual modes

  * By setting it to the MO position, it switches to manual focus by rotating the focus ring even during continuous AF. 
  The default setting of Full-time MF function varies for each mount.
