Approximately 50% lighter, delivering greater flexibility
As a frequently used focal length, this lens pursues uncompromising compactness and lightweight design.

One FLD glass element, three SLD glass elements, and three double-sided aspherical lenses are effectively arranged to achieve an approximately 30% shorter length and 50% lighter weight compared to the predecessor, Sigma 16mm F1.4 DC DN | Contemporary.

As the lightest lens in the Sigma F1.4 DC series, it accelerates creative freedom by further enhancing the mobility of APS-C cameras.

Uncompromising sharpness across the entire image

Pursuing even higher optical performance
The Sigma 15mm F1.4 DC | Contemporary was developed with the goal of  surpassing the highly acclaimed optical performance of the predecessor, Sigma 16mm F1.4 DC DN | Contemporary. Particular emphasis was placed on improving edge-to-edge performance while thoroughly suppressing sagittal coma flare, which is often noticeable in large-aperture wide-angle lenses. The lens  maintains uncompromising sharpness across the entire frame, even when shooting wide-open, delivering consistent performance from everyday street photography to starry landscapes.

Rich expressive power with a large F1.4 aperture
The lens delivers high optical performance even at its maximum aperture, allowing you to fully enjoy the distinctive rendering of F1.4. It excels in low-light conditions, such as dim indoor environments or nighttime street photography, while the nine-blade aperture produces beautiful circular bokeh that makes subjects stand out and adds a sense of depth, whether shooting stills or video.

Designed to minimize flare and ghosting
Using advanced simulation technology, flare and ghosting have been largely eliminated, ensuring that the lens renders clear, high-contrast results in any lighting condition.

Designed for comfortable shooting of both stills and video

Ideal for high-quality video production
The Sigma 15mm F1.4 DC | Contemporary, with its combination of portability and outstanding optical performance, enables high-quality video capture in any scene. Its F1.4 aperture creates a shallow depth of field that enhances three-dimensionality, producing impressive visuals. The lens is also well-suited for gimbal-based shooting, providing flexibility even in environments that demand mobility.

Furthermore, the lens delivers stable, high image quality for business applications such as live commerce, webinars, and corporate promotions, making it ideal for creating engaging and realistic content.

Smooth, responsive autofocus powered by a stepping motor
High-speed, high-precision autofocus is achieved by driving a lightweight focus lens with a stepping motor that enables precise control. The Sigma 15mm F1.4 DC | Contemporary captures important moments without missing a beat, even in fast-moving scenes, while delivering excellent tracking performance for high-quality video production.

Minimal focus breathing
The lens is designed to minimize changes in the angle of view caused by focusing, enabling smooth, natural-looking focus pulls when recording video.

Aperture ring or control ring with various functions
Equipped with an aperture ring for intuitive control of the aperture. The Canon RF Mount version has a control ring instead of an aperture ring, allowing customizations of functions based on the user’s preferred settings.

Dust- and splash-resistant structure¹ / water- and oil-repellent coating
In addition to a dust- and splash-resistant structure1, the frontmost surface of the lens has a water- and oil-repellent coating applied, allowing photographers to shoot without concern even in harsh outdoor environments.

1. The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.
