The SIGMA 24mm F2 DG DN | Contemporary – part of the I series range of premium compact prime lenses – offers superb optical performance, a bright F2 aperture, an all-metal build and a manual aperture ring. Designed from the ground up for mirrorless systems, it feels perfectly-balanced on modern full-frame bodies, and boasts exceptional resolving power that can keep up with the latest ultra-high-resolution cameras.
The lens's advanced optical design produces sharp, high-contrast results from the center of the frame to the far corners, and together with its F2 aperture and wide angle-of-view, it's an excellent choice for night sky photography, events and interiors. Thanks to its compact size, the lens can be carried around effortlessly, which makes it perfect for day-to-day use. The high quality, all-metal construction, which is found on all of SIGMA's I series models, makes the experience of owning and operating this lens extremely satisfying.
I series｜Premium Compact Primes for mirrorless users
The SIGMA I series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve.
One of the key advantages of mirrorless cameras is their smaller form-factor, and this 24mm optic is designed to be perfectly matched to these more compact systems without sacrificing performance. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers.
New standards of optical performance for the Contemporary line
The SIGMA 24mm F2 DG DN | Contemporary, like the SIGMA 35mm F2 DG DN | Contemporary and the SIGMA 65mm F2 DG DN | Contemporary, combines the highest level of optical performance even at its maximum aperture of F2 and a well-balanced body.
The lens uses two SLD glass elements and one FLD glass element to correct axial chromatic aberration, which is a particular concern with bright lenses. It also incorporates two high-precision glass-molded aspherical elements, made possible by the processing technology of SIGMA's sole production facility in Aizu. This has enabled the total number of lens elements to be kept down and the size and weight of the lens to be reduced, while providing excellent correction of various aberrations.
In anticipation of wide-angle lens applications, SIGMA's optical designers have ensured the lens resolution is extremely high, and is uniform from the center to the periphery of the image. Sagittal coma flare is also well suppressed, giving the lens a high degree of rendering power that makes it ideal for night sky photography.
The AF drive system incorporates a quiet, high-speed stepping motor. This allows photographers to capture every detail of the spacious 24mm scene with quick, accurate, silent AF.
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 that improves the quality of the entire product. 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 cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use.
The cover ring between the focus ring and the aperture ring has hairline processing that is also used for the rear cylinder of the Art line. This covering functions as a finger hold when attaching or detaching the lens.
