The black 30mm f/2.8 DN Lens from Sigmahas a minimum focus distance of 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.
Inner focusing system and linear autofocus motor for efficient, smooth, quiet and accurate focus.
Two glass molded aspherical elements, including a double-sided aspherical element and Super Multi-Layer Coating minimizes aberrations and reduces flare and ghosting for sharp, high contrast images.
A brass bayonet mount has both high accuracy and durability. A special treatment to reinforce its strength is applied to the surface giving it greater strength and making it highly resistant to long-term use.
