Sigma 14mm F1.4 DG DN

Leica L-Mount

Review

The Sigma 14mm F1.4 DG DN is a remarkable wide-angle lens specifically designed for full-frame mirrorless cameras, and it’s an impressive addition to the L-Mount ecosystem. Known for its exceptional image quality, this lens caters to landscape, astrophotography, and architecture enthusiasts who need a fast aperture and sharp performance across the frame.

One of the standout features of the Sigma 14mm F1.4 DG DN is its large maximum aperture of f/1.4, which offers excellent low-light performance and beautiful bokeh. This fast aperture allows photographers to capture stunning night sky images with minimal noise while keeping the stars in sharp focus. Additionally, the lens contains advanced optical elements, including low dispersion (LD) and aspherical glass elements, which effectively minimize chromatic aberrations and maintain high resolution throughout the image.

In terms of build quality, the lens feels robust with its weather-sealed construction, making it suitable for outdoor shooting in various conditions. The user-friendly design includes a de-clickable aperture ring, which is ideal for videographers looking to achieve smooth exposure transitions without noticeable clicks.

However, there are a few considerations to keep in mind. The lens, while well-composed for its quality, is relatively heavy compared to other wide-angle options, which might be a drawback for those who prioritize portability. Additionally, being a 14mm lens, there can be a strong distortion at the edges, which is typical in ultra-wide-angle lenses, though it is well-controlled here.
