Unmatched large bokeh opens up new expressive possibilitiesThe standout feature of the Sigma 135mm F1.4 DG | Art is its remarkably large bokeh. With an impressive effective aperture diameter*1, this lens delivers extraordinary bokeh that surpasses even the Sigma 105mm F1.4 DG HSM | Art, famously known as the “Bokeh Master.” Its performance rivals that of the Sigma 200mm F2 DG OS | Sports, offering breathtaking depth. The 135mm focal length provides a natural perspective, and when combined with its stunning bokeh, it beautifully emphasizes the subject, crafting dimensional portraits that are truly unique to this lens. |
Optical design optimized to produce the natural bokehMeticulous correction of chromatic aberration, a frequent challenge in telephoto lenses, ensures pristine bokeh free from color fringing. The lens design further reduces vignetting, producing smooth, near-circular bokeh that remains natural even at the edges—making full use of the wide-open aperture’s potential. |

Sigma’s craftsmanship behind the beautiful bokehA 13-blade diaphragm ensures a perfectly circular bokeh, while the meticulous craftsmanship in aspherical lens processing elevates its silky smooth quality. This exquisite, natural bokeh is a testament to Sigma’s extensive expertise in developing F1.4 prime lenses over the years, combined with the cutting-edge manufacturing techniques honed at the renowned Aizu factory. |
Clear subject detail even at maximum apertureFour sizable FLD glass elements are meticulously arranged, accompanied by precisely positioned high-dispersion glass components to effectively minimize axial chromatic aberration, a challenge often intensified in large-aperture telephoto lenses. This thoughtful design ensures sharp, detailed subject rendering even at wide-open apertures, fully capitalizing on the beautifully shallow depth of field that distinguishes the 135mm F1.4 lens. |

Floating focus system for consistent sharpnessA floating focus system operates by moving two focus lens groups independently, guaranteeing exceptional resolution and sharpness throughout the entire focus range. |
Dual HLA for fast, precise autofocusThe dual HLA (High-response Linear Actuator) system operates by leveraging two independent HLAs, each dedicated to a specific focus group. This innovative design combines two uniquely optimized HLAs—one tailored for extensive movement and the other for precision. Together, they deliver the power required for large-aperture telephoto lenses while ensuring rapid and accurate autofocus performance. This sophisticated system enables the capture of fleeting expressions and fast-moving subjects with remarkable precision and reliability. |

Designed to minimize flare and ghostingFlare and ghosting, which can diminish image quality, are meticulously minimized under all lighting conditions through the use of advanced simulation technology and Sigma’s renowned Super Multi-Layer Coating. This exceptional backlight resistance ensures crisp, clear, and sharp images, regardless of the lighting environment. |
Various shooting assist functionsThe lens features an AFL button conveniently positioned in two locations, allowing for a variety of customizable functions through the menu on compatible cameras. Alongside the aperture ring, it includes an aperture ring lock switch and a click switch, offering the flexibility to enable or disable the click as needed. |
