Optical Performance That Meets The Requirements
Of High-End Cine Lenses
This SIGMA 40mm F1.4 DG HSM Art lens for L-mount 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-resistant 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.
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.
Native L-mount For A More Rigid And Stable Feel
Making the lens mount native for L-mount provides a much more rigid and stable feel to the lens than using an adapter. Featuring a surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-resistant construction.
