Sigma 24mm F3.5 DG Full-Frame Contemporary Lens with Manual Aperture Ring (Black, L Mount)

Mirrorless systems now provide fresh value with the Sigma 24mm F3.5 DG Contemporary Lens in Black for L Mount, a full-frame compatible lens. Excellent optical performance combined with a level of portability that is ideal for lighter and more compact contemporary mirrorless cameras will open up new possibilities for the ideal shot. The Sigma 24mm F3.5 DG Contemporary matches the newest high-resolution mirrorless cameras with its ultra-high resolving power and outstanding optical performance. With its silent, high-speed stepping motor, the AF drive system can be used for both still and video photography.

Setting a New Contemporary Benchmark

When photographing wide-angle scenes, photographers can rely on edge-to-edge clarity at all apertures because the 24mm F3.5 DG Contemporary's strong resolving capability covers the entire image from the center to the edges. Photographers can more freely explore a topic with its lowest focus distance of about 10 cm and maximum reproduction ratio of 1:2. This allows them to take close-ups of smaller things or vast landscapes. It provides photographers with near-circular out-of-focus highlights, even at the frame's edges, in addition to the visually appealing bokeh. This makes it easier to get a close-up of an in-focus subject with a blurred background - a technique that works well in many different situations. The most recent optical design, tailored for mirrorless systems, is present in the lens. This comprises SLD glass and high refractive index glass elements, as well as high-precision, glass-molded aspherical elements made with sophisticated processing technologies. When combined, they enable the combination of compactness and good optical performance. The 24mm F3.5 DG Contemporary is a popular option for video recording due to its smooth focus drive technology, which is built around a silent and quick stepping motor.

Precise Aspherical Glass Molded Lens

The surfaces of molds used for glass molding must be extremely precise. Sigma achieves this by employing high-precision molds with surface control to an accuracy of plus and minus 5 nanometers (0.000005 mm) or less. These precise aspherical glass-molded lenses offer excellent aberration correction while maintaining a compact lens design.

Superior Quality in a Compact Size

Every lens in the I series is made entirely of metal. In addition to giving the barrel a sleek, fashionable appearance, the precision-cut aluminum components offer exceptional longevity, raising the caliber of the finished product. For increased durability, interior structures that slide with the operating ring are also made of metal. These high-precision parts, which are made using Sigma's state-of-the-art metalworking technology, are also utilized in the company's Cine Lens line for professional filmmakers. They offer a beautiful tactile feel and sound effects that entice photographers to reach for and play with them repeatedly. Hairline processing, which is also utilized for the Art line's rear cylinder, is applied to the cover ring, which is situated between the focus and aperture rings. When the lens is attached or detached, this covering serves as a finger grip.

Magnetic Metal Lens Cover

Along with a standard plastic cap, the lens comes with a specially designed magnetic metal lens cover. This unique metal cap securely attaches to the front of the lens via magnets. It can be confidently stated that this carefully designed cap serves as the perfect final detail for the lens.

Inner Focus System

Moveable internal lens components that change focus without affecting lens barrel length are used in this lens' construction to improve stability.

Lens Aberration Correction Compatibility

In order to further improve image quality, this feature adjusts chromatic aberrations, distortion, peripheral lighting, and other issues in-camera while matching the optical properties of the lens.

Sigma's Super Multi-Layer Coating

By blocking internal reflections, Sigma's proprietary Super Multi-Layer Coating reduces flare and ghosting. This original technology is present in every lens in the current Sigma lineup. In digital cameras, reflections between the surfaces of the lens and image sensor can also result in flare and ghosting. Sigma's Super Multi-Layer Coating works incredibly well here, delivering images with exceptional contrast.

Aperture Ring and Focus Mode Switch

The purpose of the aperture ring is to facilitate intuitive operation. The focus mode can be changed from AF to MF by using the Focus Mode switch.

Linear and Non-linear Focus

A mirrorless lens focus movement technique for mirrorless cameras in connection to the focus ring's rotational angle during manual focusing. The degree of focal point movement with 'non-linear focus' changes according to the speed at which the focus ring rotates. With linear focus, the amount of focal point movement is independent of the focus ring rotational speed as long as the focus ring rotational angle stays constant.

Stepping Motor

In addition to supporting Face and Eye Detection AF and video AF, the lens can achieve smooth, silent, and fast AF thanks to a stepping motor. Rubber sealing is incorporated into the lens mount to shield it from water and dust.

Other Highlights

The lens features a rounded diaphragm and high-speed autofocus compatibility. It works with the Sigma USB DOCK UD-11 (L-Mount only, sold separately) and has a high-precision, durable brass bayonet mount. Supporting DMF and AF plus MF, it is designed to minimize flare and ghosting. Each lens undergoes Sigma's proprietary MTF measuring system and includes a magnetic metal lens cap.
