Sigma Unveils the World’s First 135mm F1.4 Autofocus Prime for Full-Frame Mirrorless
Sigma has announced a groundbreaking addition to its celebrated Art series: the Sigma 135mm F1.4 DG | Art, the world’s first autofocus 135mm F1.4 prime lens designed for full-frame mirrorless cameras. Scheduled for release in late September 2025 at a retail price of $1,899 USD, this lens is set to redefine professional portraiture and establish new benchmarks for optical excellence.
The 135mm focal length has long been a favorite among portrait photographers for its natural compression and immersive depth. By pairing this perspective with an ultra-bright F1.4 aperture, Sigma delivers not only striking subject isolation but also a creamy, three-dimensional bokeh that melts backgrounds away. This combination makes the lens a dream tool for wedding, fashion, and fine art portraiture, where the interplay between sharpness and blur becomes the essence of the image.
Sigma has equipped the lens with its HLA (High-response Linear Actuator) autofocus motor, ensuring speed, precision, and near-silent operation. This performance is further supported by thoughtful features for professionals, including a de-clickable aperture ring for smooth transitions during video shooting and multiple customizable AFL buttons placed on both the side and top of the lens barrel for intuitive control.
Inside, the optical design showcases Sigma’s engineering prowess: 17 elements in 13 groups, including 4 FLD (“F” Low Dispersion) and 2 aspherical elements. This arrangement minimizes chromatic aberrations, suppresses flare, and ensures sharpness from center to edge, even wide open at F1.4. The lens’s construction also follows the rugged standards of the Art line — dust and splash-resistant, gasketed around the mount, and with water- and oil-repellent coatings on the front element.
The Sigma 135mm F1.4 DG | Art is not just another telephoto portrait lens; it is a bold statement of intent from Sigma to push boundaries where others hesitate. For photographers striving for uncompromising quality, dramatic depth, and the sheer artistry of bokeh, this lens will likely become a new standard bearer in the world of portraiture.
