Ultra-Small, Ultra-Light, Ultra-Sharp

Designed for photographers and film-makers who value the experience of taking a picture just as much as the quality of the final result, the 24mm F3.5 is a premium compact prime that forms part of Sigma’s I series range of lenses.

Weighing in at just 225g, it is exceptionally lightweight for a high-performance full-frame lens, making it one of the most portable wide-angle lenses on the market for mirrorless users.

The 24mm F3.5 is constructed of 10 elements, including 3 aspherical elements and 1 SLD element, which help keep the lens small and light and reduce unwanted aberrations. Image quality is exceptional across the whole frame, even with the lens wide-open at F3.5. As with Sigma’s other I series lenses, the 24mm F3.5 combines its superb optical performance with outstanding build quality and retro styling. Its sleek, all-metal body includes a metal focus ring, a metal aperture ring, a metal lens hood, and even a metal lens cap that attaches to the lens magnetically.

Well-controlled flare and ghosting, even in very bright direct sunlight, ensures punchy, high-contrast results in all conditions.

Excellent Build Quality

As with the other optics in the I series range of premium compact primes, the 24mm F3.5 has an all-metal build comprising precision-cut aluminium parts. Its robust construction and ultra-portable design make it perfect for street, travel, wedding and landscape photography, or any situation where having lightweight kit is important. The lens has a dust- and splash-proof mount to help keep it safe in difficult shooting conditions.

A manual aperture ring allows aperture to be controlled either by the lens, or, in Auto mode, by the camera if preferred. The action is smooth and precise, ensuring the very best lens ergonomics.

The tactile knurled metal finish used for the lens hood, focus ring and aperture ring make handling the lens and changing settings extremely intuitive. Included with the lens is a magnetic metal lens cap in addition to the regular plastic cap, which further improves ease of use.

• Metal mount with seal: Protects against dust and moisture.
• Metal aperture ring: Allowing aperture adjustment via the lens or the camera.
• Metal focus ring: A smooth, well-damped action for precise focus adjustment.
• Ultra-compact body: Weighs only 225g, ideal for landscapes, street and travel.
• Petal-shaped hood: All-metal with individually machine knurled grooves.

High-Performance Optics

Despite being extremely small and light, the 24mm F3.5 does not compromise on optical quality. Its advanced optical design includes 10 elements in 8 groups, of which 3 are aspherical elements and 1 is an SLD element. These help keep the lens compact while greatly reducing the appearance of chromatic aberration around areas of high contrast.

Vignetting is very minimal even wide-open, which is an important feature on a wide-angle optic.

Super Close-Up Ability

The 24mm F3.5 has an exceptionally impressive magnification ratio of 1:2, which means it can focus very close to the subject to capture macro-style images. The minimum focusing distance is just 10.8cm from the sensor to the subject, which makes the working distance between the lens and subject less than 6cm.

Sigma I Series Range

The lens is part of the I series range of primes, which sit in the Contemporary line-up. They are designed to offer mirrorless photographers outstanding optical quality ad premium usability in a compact package.

With similar optical character and the same sleek external design, the lenses are ideally used as a set, ensuring consistent bokeh, colour rendition, optical precision and usability.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
