Sigma 20mm F1.4 DG DN Art

Leica L-Mount

Review

The Sigma 20mm F1.4 DG DN Art lens is an impressive ultra-wide-angle option designed specifically for full-frame mirrorless cameras, particularly those with the L-Mount. With its combination of a large aperture and exceptional optics, this lens stands out as a versatile choice for landscape photography, astrophotography, and even environmental portraits.

One of the key highlights of this lens is its fast f/1.4 aperture. This allows for stunning low-light performance, making it an excellent companion for nighttime shooting and capturing starry skies. The lens excels in providing a shallow depth of field, enabling photographers to create vivid bokeh effects while keeping the subject sharply in focus. When it comes to optical quality, the Sigma Art series is known for its impressive resolution and contrast, and the 20mm f/1.4 does not disappoint. This lens produces sharp images even when shot wide open, retaining excellent details and high fidelity.

Another notable feature is the construction quality. The lens is robust, built with high-quality materials that ensure durability. The weather-sealing adds an additional layer of protection against dust and moisture, which is a significant advantage for outdoor photographers. The focusing mechanism is smooth and quiet, making this lens suitable for both photography and video work.

However, there are some downsides to consider. The Sigma 20mm f/1.4 is relatively large and heavy compared to other ultra-wide offerings. It may not be the best choice for photographers who prioritize portability and compactness. Additionally, while the lens provides excellent optical performance, distortion can be noticeable at the edges, particularly in architectural photography, requiring correction in post-processing.
