Lens Description: The black 19mm f/2.8 DN Lens for Sony E-mount Cameras from Sigma is a wide-angle prime lens for Sony E-mount cameras. Its 35mm focal length equivalency is 28.5mm and its minimum focus distance is 7.9" (20 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 three glass molded aspherical elements, aberrations are kept to a minimum. The result is accurate color definition and sharp imaging across the frame.
