Contemporary Sigma 30 mm f/1.4 DC DN lens for Sony E
A fast and versatile primordial lens, this 30 mm f/1.4 DC DN Sigmaestá Contemporary lens designed for cameras without mounting mirror and Sony APS-C format, where it provides an equivalent focal length of 45 mm. The bright maximum aperture of f/1.4 benefits work in low light conditions and also allows extensive control over placement of the focus for the use of selective focusing techniques. With regard to the optical design, a aspheric element and a pair of double-sided aspherical elements significantly reduce spherical aberrations for clarity and definition for a remarkably clear picture quality. A high refractive index element is also included, to minimize color fringes and chromatic aberrations, and a super-multilayer coating has been applied to control the flash and phantom effect of the lens under lighting conditions. Intense. In addition, benefiting both the shooting and video recording, this compact compact also incorporates a step-by-step or soft AF motor, almost silent auto-focus performance. Designed as a versatile standard lens, the combination of speed and optical dexterity makes this a lens to go to non-mirror handles.
This truly versatile 30mm standard lens is designed for cameras without mounting mirror and Sony APS-C format, providing an equivalent focal length of 45 mm.
The maximum aperture of f/1.4 fast excels in low light conditions and also offers greater focus control to produce shallow field effects.
A aspheric element and a double-sided aspheric element control a range of spherical aberrations and distortions for clarity and resolution. In addition, a high-dispersion index glass element is also integrated into the design and offers anomalous partial scattering characteristics to control chromatic aberrations and reduce the color fringe.
A super multi-layer coating has been applied to the lens elements to minimize the reflection and phantom image of the lens and contribute to producing contrast-rich, neutral-coloured images even under backlit conditions.
A step-by-step AF motor benefits both photographers and videographers with their fast, accurate and almost silent performance.
A rounded nine-leaf diaphragm contributes to a pleasant quality of bokeh.
The lens is constructed with a thermally stable composite material (TSC), together with traditional metals, for greater accuracy and use in wide temperature variations. The outside of the lens cylinder is also engraved with the year of production.
The bayonet mount is made of brass to ensure accuracy and durability.
