Sigma 30mm f1.4 DC DN Contemporary - X Mount - 1164711

SIGMA 30mm F1.4 DC DN | Contemporary large-aperture standard lens gives owners of mirrorless cameras the opportunity to experience the fun of shooting wide open, with F1.4 brightness. Photographers will enjoy the beautiful bokeh effect that only a large-aperture lens can offer and the exceptionally sharp optical performance expected from a fine prime lens. Leveraging SIGMA’s latest technologies and design insights, this new lens fulfills the concept of the Contemporary line, in which varied elements come together in optimal balance.
A prime lens with a focal length of around 50mm and F1.4 brightness offers an angle of view very similar to human vision. The photographer can use the shallow depth of field at a wide-open aperture to take stunning portraits and tabletop still life shots. Or he or she can close the aperture for greater depth of field and shoot landscapes or snapshots. In this way, standard lenses allow photographers to enjoy so many of the fundamental methods of photography and have thus been favorites for decades. Photographers can experience F1.4 brightness and standard lens functionality with a 35mm equivalent focal length of 60mm on the Micro Four Thirds system, 48mm on the Canon EF-M Mount system, and 45mm on other systems.

For optimal balance with light, compact camera bodies with a short flange back distance, SIGMA designed the new SIGMA 30mm F1.4 DC DN | Contemporary lens to be extremely compact. Moreover, the special design of the focus lens group allows fast and smooth AF performance for videography and more. This lens combines a compact design and comfortable operation while prioritizing outstanding image quality. Featuring SIGMA’s latest technologies, this lens digitally corrects optical distortion.

The included lens hood is extra-long and features an anti-reflective coating to manage unwanted light. The hood also features rubber and anti-slip textures to make it easier for the photographer to hold while shooting.

Since new material TSC (Thermally Stable Composite) is highly elastic, it exhibits minimal deformation. Parts made of TSC are therefore less prone to develop gaps between each other over time. The SIGMA 30mm F1.4 DC DN | Contemporary features a lens barrel and aperture parts made of TSC, which contribute both to the compactness of the lens and the smooth functioning of the aperture system. TSC helps increase the precision of cells holding lens elements and parts related to the focus lens group, further enhancing lens performance.

The front lens element features a high-refractive index, high-dispersion glass for extra power, and a shorter overall lens length. To optimize the lens for mirrorless cameras, two aspherical lens elements help ensure outstanding image quality and overall compactness. The SIGMA 30mm F1.4 DC DN | Contemporary features SIGMA’s inner focus technologies, while lighter lens elements in the focus lens group make possible a more compact actuator. Moreover, this lens offers outstanding stability whether the photographer is shooting handheld or has the camera placed on a surface. Structurally, the lens features materials and parts that contribute to its compact, lightweight structure. In summary, this is an unprecedented lens that combines outstanding optical performance with exceptional portability and usability.

The mount features a special sealing* to make the lens an excellent choice in a wide variety of conditions.

In addition to featuring an optimized layout and power distribution, this lens incorporates one aspherical lens element and one double aspherical lens element, as well as an element made of high-refractive-index, high-dispersion glass with high anomalous partial dispersion. By effectively leveraging these technologies, the lens delivers an outstanding level of light to the edges of the image while minimizing transverse chromatic aberration. To correct distortion, the lens takes advantage of the image correction* capabilities of the mirrorless camera body, using the corrective power of the optical system to enhance sharpness. The final result is an extremely compact lens that delivers image quality that rivals that of Sigma Art line lenses.

From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.

The large-diameter lens with F1.4 brightness makes possible a shallow depth of field for a beautiful bokeh effect—unavailable until now in a standard lens for mirrorless cameras.

The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

What our Experts Think

• Versatile daily standard prime: Experts highlight the natural 45 mm full‑frame equivalent field of view on Fujifilm X, making it ideal for street, portraits, travel, and everyday shooting.
• Bright low‑light performance: The fast f/1.4 aperture lets you shoot in dim conditions with better control over depth of field and strong subject separation.
• Sharp optics with great clarity: A pair of aspherical elements and a high‑refractive index element reduce aberrations and distortion, delivering crisp, well‑defined images across most apertures.
• Smooth AF for stills and video: Stepping motor autofocus offers quiet, responsive focusing – beneficial for both photography and videography.
• Compact, lightweight build: At ~275 g, it’s easy to carry all day without compromising build quality or performance.
• Excellent value overall: Reviewers often note it outperforms typical kit zooms in sharpness and bokeh for the price, making it a high‑value upgrade for X‑mount shooters.
