Sigma 24mm F 1 4 DG HSM Art Análisis | 54 Datos comparados

The Sigma 24mm f/1.4 DG HSM Art lens delivers exceptional image quality at a competitive price point, featuring a sharp center at f/1.4 that becomes highly uniform at f/2.8. Its robust build, fast autofocus, and smooth manual focus ring represent key advantages in the 24mm market. Conversely, the lens exhibits significant wide-open corner softness and vignetting that requires stopping down, and it lacks weather-sealing and optical stabilization found in some competitors.

The Henry's Note review of the Sigma 24mm F1.4 DG HSM Art lens highlights its exceptional optical performance, featuring a complex design that produces beautiful, round bokeh and a versatile 35 cm close-focusing distance. While delivering high-quality images, the lens lacks weather sealing and a durable, fully metallic barrel compared to competitors. Additionally, the focus-by-wire system requires powered camera operation and expensive adapters, posing potential limitations for specific shooting scenarios.

The Sigma 24mm f/1.4 DG HSM Art lens is a highly impressive, wide-angle prime lens built from Thermally Stable Composite (TSC) material, offering excellent resistance to temperature extremes and a manageable weight of 23.5 oz (665g). The reviewer praises the lens for its phenomenal, class-leading corner-to-corner sharpness even when shooting wide open at f/1.4, which is aided by FLD and SLD glass elements. Additional performance highlights include a remarkably quiet and fast Hyper Sonic Motor (HSM) autofocus system with manual override, an incredibly close minimum focusing distance of 9.8 inches, and a beautifully smooth, "dreamy" bokeh produced by its nine rounded aperture blades. Despite its stellar performance, the lens does have a few minor drawbacks, notably a minute amount of purple fringing (chromatic aberration) on highly backlit objects that is visible under 3:1 magnification, and visible vignetting at apertures wider than f/2.8. While the lens barrel feels robust and mimics metal, a crucial post-publication correction clarifies that this lens is entirely lacking weather sealing. Furthermore, it does not feature built-in optical image stabilization, though this omission is common for a...

The Photography Life review of the Sigma 24mm f/1.4 DG HSM Art highlights a robust, "built like a tank" lens offering exceptional value with stunning, elite-tier center sharpness at f/1.4. It features a durable metal barrel, very low barrel distortion (0.16%), and excellent flare resistance. However, the lens suffers from pronounced field curvature, causing poor performance in the mid-frame and extreme corners at wide apertures, which requires stopping down to f/5.6 for optimal sharpness. Other drawbacks include a lack of official weather sealing and a focus ring direction that differs from native lenses.

This review evaluates the Sigma 24mm f/1.4 DG HSM Art lens, a moderate ultra-wide-angle lens designed for full-format cameras that offers a budget-friendly alternative to native lenses. A major pro of this lens is its exceptional, professional-grade build quality, which incorporates metal parts and Thermally Stable Composite (TSC) material for a premium feel. It features a smooth, rubberised focus ring, internal focusing to keep the physical length constant, and a virtually silent, fast ultrasonic autofocus drive (HSM). Furthermore, at roughly 850 USD (800 EUR), it provides immense value compared to competitors like the Canon EF 24mm f/1.4 L II, which costs nearly double. Users can also fine-tune AF calibration independently using the optional Sigma USB dock. Despite these strengths, the review notes a couple of notable downsides. The most significant con is the complete lack of weather sealing, which may deter outdoor photographers who shoot in harsh environments. Additionally, while the contrast autofocus performs adequately in Live-View mode and has improved on recent DSLR bodies, it is still at its best when relying on conventional phase-detection modes. Overall, the lens...
