Sigma 20mm F2.0 DG DN C for Sony E Mount - Black

Key Features 

• All I Series lenses feature an all-metal body, with high-precision metal internal parts, and a metal hood. 

• All I Series lenses feature a manual aperture ring and knurled surfaces for an enjoyable tactile experience. 

• The F2 I series lenses have comparable MTF chart optical performance to SIGMA DSLR F1.4 Art lenses 

• The L-mount version of the new 20mm F2 DG DN | C introduces a Linear/Non-Linear manual focus operation. The option may become available for certain other I series lenses in L-mount only at a later date via firmware updates. 

• The new 20mm F2 DG DN | C features the signature arc-type auto/manual focus switch, a dust and splash-resistant mount, a knurled lens hood, and magnetic lens caps, as do the 24mm F2 DG DN | C, 35mm F2, and 65mm F2. 

• The 24mm F3.5 shares a 55mm filter thread diameter with the 45mm F2.8 DG DN C and the 90mm F2.8 DG DN C, which makes for a very compact system that can accept the same filters and lens caps*, perfect for travel, adventure, etc. where compactness and versatility really matter. *45mm is not compatible with the metallic magnetic caps. 

• An optional magnetic cap holder (CH-11) features a mini-carabiner for clipping to a bag, jacket or belt loop, and has a donut-style center hole to easily remove the cap when it is time to place back on the lens.
