The 30mm f/2.8 DN Lens for Sony E-mount Cameras from Sigma is standard length prime lens for Sony E-mount cameras. Its focal length is equivalent to a 45mm lens in the 35mm format and its minimum focus distance is 11.8″ (30 cm). Its f/2.8 maximum aperture is ideal for shallow depth of field imaging and allows it to maintain sharpness in low light situations. An inner focusing system means the lens does not extend when focusing and its newly developed linear autofocus motor is accurate and quiet. Sigma’s Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even at the maximum aperture, and with two glass molded aspherical elements including a double-sided aspherical element, aberrations are kept to a minimum. The result is accurate color definition and sharp imaging across the frame. A metal exterior provides durability and handsome design.
