Sigma 105mm F1.4 DG HSM Art

Leica L-Mount

Review

The Sigma 105mm F1.4 DG HSM Art lens is a remarkable addition to the L-Mount lineup, prized for its stunning optical performance and impressive build quality. Designed for portraiture and low-light situations, it offers a fast f/1.4 aperture that creates exceptional depth of field and beautiful bokeh, making it a popular choice among professional photographers and enthusiasts alike.

When it comes to image quality, this lens truly excels. It incorporates advanced optical design elements that minimize aberrations and distortion, resulting in sharp, clear images even at wide-open apertures. The lens uses high-quality glass elements, including several Special Low Dispersion (SLD) glass elements, which contribute significantly to correcting chromatic aberrations. As a result, colors appear vibrant, and the overall image quality maintains exceptional contrast and clarity throughout the frame.

The build quality of the Sigma 105mm F1.4 Art lens is another standout feature. It boasts a rugged and weather-sealed construction, ensuring that it can withstand challenging shooting conditions. The lens feels robust in hand, with a smooth focusing ring and a solid, premium feel that befits its Art designation. Additionally, its relatively compact design for a lens of this focal length and aperture makes it easy to handle for extended shoots.

However, there are some considerations to keep in mind. The Sigma 105mm F1.4 is certainly on the heavier side, tipping the scales at around 1,500 grams (approximately 3.3 lbs). This heft may be tiring for some photographers during long sessions, and it could be an inconvenience when mobility is essential. While the lens is compatible with L-Mount cameras, some users may find that focusing can be a bit slower than expected in low-light conditions, although this is relatively minor.

Pros and Cons

Pros

• Exceptional image quality with outstanding sharpness and contrast.
• Beautiful bokeh and depth of field control thanks to the fast f/1.4 aperture.

• Autofocus performance can be slightly sluggish in low-light conditions.

Verdict

In conclusion, the Sigma 105mm F1.4 DG HSM Art lens for L-Mount is a phenomenal option for photographers who value optical excellence and build quality above all. While its weight and autofocus performance in low light may be drawbacks for some, the overall performance, especially in portrait work, far outweighs these minor inconveniences. If you're looking for a top-tier portrait lens that delivers stunning results, the Sigma 105mm F1.4 is a fantastic choice that won't disappoint.
