Exceptional I series build quality with a compact form-factor
All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability. Metal materials are also used in internal structures that slide with the operation ring for added robustness. These high-precision components crafted with SIGMA's cutting-edge metalworking technology are also used in SIGMA's Cine lens line-up for professional cinamatographers and provides an exquisite feel to touch as well as sound effects. 

Focal lengths covering everything from wide-angle to mid-telephoto
The I series consists of seven all-metal lenses in a very compact size, without compromising on optical performance. All I series lenses have the same sleek look, with focal lengths covering everything from ultra-wide-angle to mid-telephoto. This means that you can create a complete setup of lenses that doesn't need weigh too much!
