A sophisticated and compact prime, the Sigma 30mm f/1.4 DC HSM Art is a versatile normal-length lens for APS-C-format Canon EF-mount cameras. Featuring a bright f/1.4 maximum aperture, this lens excels in difficult lighting conditions and also affords increased control over depth of field for isolating subjects using selective focus. The optical design incorporates one aspherical element, which helps to reduce distortion and spherical aberrations in order to realize accurate subject rendering and high sharpness. A Super Multi-Layer Coating has also been applied to individual elements to suppress ghosting and flare for greater contrast when working in strong lighting conditions. Complementing the optical assets, this lens also features a Hyper Sonic Motor, along with a rear focusing system, that affords especially quick, quiet, and accurate autofocus performance, along with full-time manual focus override.
The SIGMA LENS 30/1.4 DC HSM Art Lens for Canon from Sigma is a prime lens designed for Canon APS-C format cameras. Its 35mm focal length equivalent is 45mm which places it in the category of standard focal length lenses. With its particularly fast maximum aperture of f/1.4, the lens will perform very well in low light situations and provides shallow depth of field focus. With updated optical configurations (9 elements in 8 groups), as well as rounded aperture blades, the lens delivers sharp detail and nice background bokeh. Its minimum focus distance is 11.8″ (30 cm).
The SIGMA “LENS 30/1.4” DC HSM Art Lens’ optimized light distribution helps to minimize field curvature preventing a loss of image quality at the edges of photographs and its double-sided aspherical lens element minimizes spherical distortion. A rear focusing system combined with a newly developed autofocus algorithm and Hyper Sonic Motor provide smooth and accurate autofocus. Fulltime manual focus is also supported. As part of Sigma’s “Art” line of lenses it is compatible with Sigma’s USB Dock, which enables firmware updates and focusing adjustments.
- Fast maximum aperture of f/1.4 allows fast shutter speeds for clear low-light imaging and shallow depth of field focus.
- A Hyper Sonic Autofocus Motor (HSM) offers fast, smooth and quiet autofocus.
- Constructed with Thermally Stable Composite Material (TSC) which performs well in extreme temperatures, reducing the expansion and contraction of the internal lens barrel.
- As part of Sigma’s “Art” line of lenses it is compatible with Sigma’s USB Dock, which enables firmware updates and focusing adjustments.
