Sigma 30mm F1.4 DC DN (C) L-Mount
This 30mm f/1.4 DC DN contemporary lens from Sigma is designed for l-mount system cameras. This provides a 35mm equivalent focal length of 45mm. The bright f/1.4 maximum aperture makes it easy to work in low-light conditions and also offers extensive control over focus for using selective focus techniques.
In terms of optical design, the lens features one aspherical element and one double-sided aspherical element that work together to significantly reduce aberrations for even greater clarity and ultra-sharp image quality. Moreover, this compact prime lens also contains a stepping AF motor for virtually silent autofocus performance.
