Amsterdam, Netherlands – In a significant development for the cinematic photography market, Sigma Corporation has officially unveiled its first autofocus cinema lens, the 28-45mm T2.0. The lens, which was showcased at the International Broadcasting Convention (IBC) in Amsterdam, is a testament to Sigma’s commitment to innovation and expansion in the professional imaging sector.
Unique Features and Design
The Sigma 28-45mm T2.0 AF Cinema Lens is built upon the successful foundation of the 28-45mm F1.8 DG DN|Art, a lens that was previously introduced as the world’s first full-frame variable aperture zoom lens with an F1.8 constant aperture. This new cinema version is designed specifically for professional use, featuring an impressive optical structure and advanced autofocus technology.
The lens incorporates 15 groups of 18 optical elements, including five FLD (F Low Dispersion) grade ultra-low dispersion glass elements and three aspherical elements. These components are designed to minimize chromatic aberration, ensuring clear and sharp images. The inclusion of FLD elements in particular enhances the lens’s ability to correct color aberrations, providing a level of image quality that is ideal for cinematic work.
Autofocus and Handling
One of the standout features of the Sigma 28-45mm T2.0 AF Cinema Lens is its autofocus capability, which is powered by the HLA (High Linear Motor) for smooth and quiet focusing. The lens’s aperture ring is designed with a stepless, cine-style focus scale for precise control, while the focus ring offers distance information with a 200-degree rotation angle, facilitating a more intuitive shooting process.
While the lens lacks an Auto Aperture A position, its focus ring provides a tactile and responsive experience that is essential for cinematic applications. This attention to detail is further underscored by the inclusion of a focus distance indicator, which is a crucial feature for many cinematographers.
Build and Specifications
The Sigma 28-45mm T2.0 AF Cinema Lens is available in both E-mount and L-mount versions, with the E-mount version measuring 155mm in length and weighing 1,250g. The L-mount version is slightly shorter at 152mm and also weighs 1,250g. Both versions utilize a 86mm filter diameter, which is slightly heavier than the 28-45mm F1.8 DG DN|Art, which weighs 950g and uses an 82mm filter diameter.
Market Position and Availability
The Sigma 28-45mm T2.0 AF Cinema Lens is a significant addition to the company’s product lineup, which has traditionally focused on high-quality still photography lenses. By entering the cinema lens market, Sigma is targeting professional cinematographers and filmmakers who require lenses that are optimized for cinematic applications.
While the pricing and release date for the Sigma 28-45mm T2.0 AF Cinema Lens have not yet been announced, its introduction is expected to spark considerable interest among professionals who are looking for a high-quality, autofocus cinema lens with an F1.8 constant aperture.
Conclusion
The Sigma 28-45mm T2.0 AF Cinema Lens represents a major step forward for the company and the cinematic photography market. With its advanced optical design, autofocus capabilities, and professional-grade build, this lens is poised to become a favorite among cinematographers around the world.
