Shallow depth of field for a beautiful bokeh effect The large-diameter lens with F1.4 brightness makes possible a shallow depth of field for a beautiful bokeh effect - unavailable until now in a standard lens for mirrorless cameras.
Designed to minimize flare and ghosting From the start of the design process, SIGMA took steps to minimize flare and ghosting and establish an optical design that is resistant to strong incidental light sources such as backlight.
Stepping motor incorporated for enhanced videography By incorporating a stepping motor, the lens offers exceptionally quick and quiet autofocusing performance. This feature is especially useful when using the camera to take videos. This lens is also compatible with Sony E-mount Fast Hybrid AF.
Minimum focusing distance of 30cm The included lens hood is extra-long and features an antireflective coating to manage unwanted light. The hood also features rubber and anti-slip textures to make it easier for the photographer to hold while shooting.
TSC used for a more compact structure and enhanced performance Since the material Thermally Stable Composite (TSC) is highly elastic, it exhibits minimal deformation. Parts made of TSC are therefore less prone to develop gaps between each other over time. The SIGMA 30mm F1.4 DC DN Contemporary features a lens barrel and aperture parts made of TSC, which contribute both to the compactness of the lens and the smooth functioning of the aperture system. TSC helps increase the precision of cells holding lens elements and parts related to the focus lens group, further enhancing lens performance.
