Sigma 23mm F1.4 DC DN | C

Leica L-Mount

Review

The Sigma 23mm F1.4 DC DN | C is an impressive addition to the L-Mount system, catering to those seeking a versatile, high-performance prime lens. Designed for APS-C sensors, this lens offers an equivalent focal length of approximately 35mm, making it ideal for a wide range of photography styles, from street and portraiture to landscape and low-light scenarios.

One of the standout features of this lens is its bright F1.4 maximum aperture. This allows for excellent subject isolation and stunning bokeh, making it a great choice for portrait photography. In low-light conditions, the wide aperture also enables faster shutter speeds, which can be critical for capturing sharp images without introducing motion blur. Additionally, the lens offers impressive sharpness from wide open, with center sharpness peaking at F2.8 and remaining impressive throughout the aperture range.

The build quality of the Sigma 23mm F1.4 DC DN | C is solid, featuring a metal mount and a well-constructed body that feels durable in hand. Its compact size and lightweight design make it portable and easy to carry, which is essential for photographers who are always on the move. The lens also integrates a customizable AF/MF switch, allowing users to quickly switch between autofocus and manual focus modes, which enhances usability in various shooting scenarios.

One area where this lens excels is its autofocus system. It employs a stepper motor that delivers fast, accurate, and virtually silent autofocus, making it suitable for both still photography and video recording. Additionally, the lens is designed to minimize optical aberrations and distortion, which is critical for achieving clean images.

However, there are a few drawbacks to consider. While the lens provides excellent performance overall, some users may find that chromatic aberration can occasionally be noticeable, particularly in high-contrast scenes. Post-processing can resolve this, but it may be an extra step for those seeking plug-and-play ease. Also, the lens hood is sold separately, which might be a slight inconvenience for some users, especially in bright conditions where lens flare can occur.
