Revolutionizing portraits with the world’s first AF 135mm F1.4.
The Sigma 135mm F1.4 DG Art is the world’s first 135mm autofocus lens to achieve a maximum aperture of F1.4, delivering exceptional expressive capabilities for portrait photography. Its unrivaled large bokeh and stunning resolution that renders every detail create an extraordinary sense of depth and dimensionality. The natural perspective and moderate shooting distance unique to 135mm, combined with the rich bokeh of the bright F1.4 aperture, make the subject stand out and render on an entirely different level compared to conventional 135mm F1.8 lenses.
Built on extensive expertise gained from developing numerous F1.4 prime lenses, this new 135mm lens from Sigma sets a new standard in portrait photography. Large bokeh for powerful visual expression. Unmatched large bokeh opens up new expressive possibilities The most notable feature of the Sigma 135mm F1.4 DG Art is its extremely large bokeh. The effective aperture diameter of the 135mm F1.4 lens produces exceptional bokeh, which is larger than that of the Sigma 105mm F1.4 DG HSM | Art known as “Bokeh Master,” and is comparable to that of the Sigma 200mm F2 DG OS | Sports. The natural perspective unique to 135mm, together with its overwhelming bokeh, highlights the subject and creates dimensional portraits achievable only with this lens.
Floating focus system for consistent sharpness A floating focus system moves the two focus lens groups independently, ensuring consistently high resolution across the entire focus range. Designed to minimize flare and ghosting Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology and Sigma’s Super Multi-Layer Coating. High backlight resistance enables clear and sharp images under any lighting conditions.
Fast, accurate autofocus to capture fleeting expressions Dual HLA for fast, precise autofocus. Each of the two focus groups is driven by its own HLA (High-response Linear Actuator), forming a dual HLA system. By incorporating two distinct types of HLAs, each optimized for the movement range of a focus group, the dual HLA system ensures both the high thrust needed for large-aperture telephoto lenses and fast, precise AF performance. This allows even fleeting expressions and fast-moving subjects to be captured with exceptional reliability.
