The Sigma 30mm f/1.4 DC DN for Sony E is a fast-aperture prime lens designed for Sony E-Mount cameras and camcorders. Key features include:
Fast f/1.4 Aperture Normal Range. The 30mm focal length provides a 45mm equivalent on crop-frame Sony E-Mount cameras. The combination of a normal focal range and fast aperture makes this lens ideal for portraiture where subject-background isolation is needed and a perfect choice for low-light shooting.
High-Quality Optics. The Sigma 30mm 1.4 packs a lot of powerful optics into a small package. A single aspherical element is combined with a double-sided aspherical element to help eliminate spherical aberrations and distortions, while increasing sharpness and resolution. A high-refractive index element reduces chromatic aberrations and helps to control color fringing. The Super Multi-Layer Coating minimizes lens flare and ghosting, while a nine-blade, rounded aperture provides a pleasant bokeh.
Stepping Autofocus Motor. The built-in stepping autofocus motor provides fast, accurate, and quiet operation in a wide variety of shooting situations. You can also manually override the autofocus motor at any time by rotating the focusing ring, giving you quick fine-tuning ability.
