The 30mm f/1.4 DC HSM Art Lens for Pentax from Sigma is a prime lens designed for Pentax 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 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.
- 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.
