(19mm equiv on Canon) focal length makes it the widest APS-C prime the company offers, and it not only features the company's sharp new branding, but a few other features that are new to its lineup of APS-C primes.
The lens is made up of 14 elements in 12 groups, with two SLD elements and three aspherical elements. It has nine aperture blades and a minimum focusing distance of 0. 17m (6. 8").
It can accept 62mm filters, and the Sony version weighs 225g (7. 9oz). Sigma says that makes it the lightest lens in its Contemporary prime lens lineup, and also says it was able to make it even shorter than its 16mm DC prime, despite its wider focal length.
It's the first dust and moisture resistant prime in Sigma's DC series
It's also the first prime in the series to gain dust and moisture resistance. Perhaps more excitingly, it's the first of Sigma's APS-C primes to have an aperture ring on the E and X mount versions, which is replaced by a multi-function control ring on the RF version.
These improvements make us wonder if there's room for Sigma to make second-generation versions of the rest of the primes in its APS-C lineup. The 16, 23, 30 and 56mm F1. 4s are still quite good lenses, but it's hard not to wish for lighter, more compact versions with aperture rings and weather sealing now that we know it's possible.
The Sigma 12mm F1. 4 DC will be available in early September at an MSRP of $629.

Press Release:
Sigma Announces Compact, Ultra-Wide 12mm F1. 4 DC | Contemporary Lens for APS-C Format Mirrorless Cameras
Ronkonkoma, NY, August 19, 2025 – Sigma Corporation of America, the US subsidiary of Sigma Corporation (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan), is pleased to introduce the 12mm F1. 4 DC | Contemporary lens for APS-C format mirrorless cameras, available in early September 2025.
The 12mm F1. 4 is the smallest and lightest of Sigma’s five DC Contemporary prime lenses, weighing in at only 7. 9 ounces, ideal for travel and everyday use for both photography and video. The ultra-wide angle of view is perfect for landscape and night sky photography, as well as video and vlogging where it’s necessary to record yourself and your surroundings at the same time. The large F1. 4 aperture provides great performance in low light, and also helps blur backgrounds to eliminate distracting elements while making the subject pop. As part of Sigma’s Contemporary line, this portable powerhouse combines simple operation with outstanding image quality, plus the latest in technical innovations to keep the lens as compact as possible. All of the photographic notes are hit with this lens.
In fact, this lens features the widest angle of view of any F1. 4 lens designed for APS-C cameras, and offers exceptional optical performance across the entire frame, even wide open, making it an excellent choice for low-light situations. With three double-sided aspherical lenses and two SLD glass elements, sagittal coma flare is well-corrected, ensuring crisp, clear images when photographing starry skies.
In addition, the 12mm F1. 4 DC | Contemporary is a great choice for video, with minimal focus breathing, a manual aperture ring (control ring on Canon RF Mount), and smooth, responsive autofocus, ideal for tracking moving subjects. Its compact size makes it perfect for handheld or gimbal use, particularly vlogging, streaming, and other settings where a wide angle of view is essential.
Furthermore, the lens features a dust and splash-resistant structure, plus a water and oil-repellant coating on the front element, to ensure high performance in virtually any conditions.
The Sigma 12mm F1. 4 DC | Contemporary lens will be available in early September at authorized Sigma dealers in the US for Sony E-mount, Fujifilm X Mount, and Canon RF Mount for a retail price of $629 USD.
