Fast f/1.4 Aperture Normal Range. The 30mm focal length provides a 60mm equivalent on Micro 4/3 cameras. The combination of a normal focal range and fast aperture makes it 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. Super Multi-Layer Coating prevents ghosting and flaring, while a nine-blade, rounded aperture provides a very pleasant bokeh.

Stepping AF Motor. The built-in stepping AF motor is great for both photographers and videographers with its fast, accurate, and ultra-quiet performance. You can use full-time manual focus control by simply rotating the focus ring.
