Sigma 23mm f1.4 DC DN I Contemporary Lens - L Mount

Introducing the Sigma 23mm F1.4 DC DN - Contemporary - L Mount

The Perfect Portable Wide-Standard Prime for Crop-Sensor Cameras

Fast. Sharp. Versatile. Portable.

Designed for crop sensor mirrorless cameras, the Sigma 23mm F1.4 DC DN Contemporary lens offers an equivalent focal length of 35mm, making it a versatile wide-standard prime. Perfect for street photography, landscapes, portraits, weddings, and travel, its F1.4 aperture ensures fast shutter speeds for hand-held shooting in low-light conditions and provides a very shallow depth-of-field for beautifully blurry backgrounds.

Despite its fast aperture, the lens weighs only 340g, making it easy to carry around all day. Its sleek yet robust build ensures durability without compromising portability. Optical performance is exceptional, delivering sharp results across the entire frame at all aperture settings. The lens pairs perfectly with other DC DN primes, which also feature F1.4 apertures.

Equivalent to 35mm on a full-frame camera, the 23mm F1.4 is ideal for street, travel, and day-to-day photography.

Features and Build

The Sigma 23mm F1.4, like other lenses in the F1.4 DC DN range, is constructed with a strong yet lightweight polymer, ensuring durability while keeping the lens portable. A large, rubberised focus ring makes manual focusing intuitive, and a petal-type lens hood helps control flare in bright sunlight.

The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture (except EF-M mount). Inner focusing technology, combined with a stepping motor, delivers smooth, fast, and accurate AF for both stills and video. The design includes lighter glass elements in the focus lens group, ensuring responsive autofocus that is fully compatible with the latest AF camera technology.

Exceptional Optical Performance

Weighing only 340g, the Sigma 23mm F1.4 DC DN | C delivers outstanding optical quality across the entire frame, even on high-resolution sensors. Its advanced optical design features 13 elements in 10 groups, including 2 aspherical elements and 3 SLD elements. This ensures razor-sharp results and helps eliminate common optical issues such as chromatic aberration, flare, and vignetting.

The lens also benefits from in-camera digital correction to fine-tune the final image. Optical performance is maintained across the whole frame, capturing fine detail perfectly right into the corners. Chromatic aberration is well-controlled around areas of high contrast, and vignetting is minimal even at wide apertures. Advanced optical coatings reduce flare and ghosting when working in bright direct sunlight – crucial for a wide-angle lens.

Excellent Low-Light Performance

With a bright maximum aperture of F1.4, this lens allows plenty of light through, making it ideal for astrophotography and hand-held shooting in low-light conditions. This aperture helps to eliminate camera shake and provides a shallow depth-of-field for impactful images with beautifully smooth and attractive bokeh, allowing photographers to isolate their subjects effectively.

Compact and Lightweight

The Sigma 23mm F1.4 and the 18-50mm F2.8 are excellent options for photographers needing a standard crop sensor lens that is both sharp and portable. While the 23mm is slightly heavier and longer, it offers a faster aperture of F1.4, allowing four times as much light and creating a shallower depth-of-field compared to the 18-50mm F2.8.
