Sigma 24mm F 1 4 DG DN Recensione | 54 Dati a confronto

The Sigma 24mm F1.4 DG DN ART lens is a professional-grade prime designed from the ground up for full-frame mirrorless cameras, correcting the flaws of its bulky DSLR-ported predecessor. Testing on the 50MP Sony Alpha 1 reveals a highly feature-rich build, including a manual aperture ring with click/declick switches, an aperture lock, a focus hold button, and a unique manual focus lock optimized for astrophotographers. The lens also features a robust weather-sealed body, a front lip to hold a lens heater, and dual-filtering capabilities utilizing both a standard 72mm front thread and a rear filter holder. Autofocus performance driven by a stepping motor (STM) proves to be instantaneous, silent, and highly accurate for both landscapes and video tracking. Optically, the lens delivers excellent real-world sharpness and contrast with minimal barrel distortion, low vignette at wide apertures, and great flare resistance when shooting directly into the sun. Longitudinal and lateral chromatic aberrations are very well-controlled, and the bokeh quality is better than average for a wide-angle lens. The primary drawback noted is that the contrast in the corners lags behind the...

Summary The Sigma 24mm f1.4 DG DN Art is a highly recommended wide-angle prime lens designed for mirrorless L-mount and Sony E-mount full-frame cameras, retailing at 899 EUR / 799 USD / 779 GBP. It features a robust, weather-sealed construction, a fast f1.4 maximum aperture ideal for low-light environments, and a minimum focusing distance of 21cm that enables pleasant background bokeh. The lens stands out for its extensive, tactile feature set, which includes a de-clickable aperture ring with an "A" position lock, a customizable AF-lock button, an AF/MF switch, and an innovative manual focus lock switch to prevent accidental focus shifts. Additionally, it supports dual filter attachment with a 72mm front thread and a unique, lever-secured rear sheet/glass filter holder, alongside an exclusive mount-conversion service offered by Sigma. Focus acquisition is fast and nearly silent at approximately 0.5 seconds, boasting a high focus repeatability score of 97.6%.

The Sigma 24mm f1.4 DG DN Art lens is a compact, lightweight, reference-level wide-angle optic featuring a dust- and splash-resistant aluminum and Thermally Stable Composite (TSC) build. The exterior offers functional controls designed for professional ergonomics, including an aperture ring that is both de-clickable and lockable, a smooth manual focus ring, a customizable AFL button, and a unique Manual Focus Lock (MFL) switch to prevent accidental focus shifts. Optically, the lens excels with a fast stepping motor that provides quick, silent, and highly accurate autofocus, even at its thin wide-open depth of field. The image quality is remarkably sharp from corner to corner at f1.4, boasting excellent rendering, minimal distortion, and strong flare resistance, while its 25cm minimum focus distance allows for creative, close-up shots with smooth, velvety background bokeh. The core benefits of this lens include its exceptional build quality, weather sealing, great autofocus accuracy, and breathtaking edge-to-edge optical performance at a highly competitive retail price of $799.

The Sigma 24mm f/1.4 DG DN ART is a professional-grade wide-angle prime lens that offers a rugged, dust- and splash-resistant build quality, a lightweight 510g body, and a smooth, rubberised focus ring. Designed with videographers and general photographers in mind, it features a snappy, noiseless STM autofocus motor, a de-clickable aperture ring, and an innovative Manual Focus Lock (MFL) switch. Optically, the lens delivers an impressive, smooth background bokeh with clean out-of-focus highlight rendering. Furthermore, it controls lateral chromatic aberrations effectively and exhibits low native barrel distortion (1.3%) in RAW files, which is easily corrected in post-processing. At roughly $800 USD, it serves as a highly affordable alternative to the $1,400 Sony FE 24mm f/1.4 GM. However, the lens falls short of its heavily advertised astrophotography potential due to weak edge-to-edge resolution at wide apertures. While the dead-centre sharpness is excellent at f/1.4, the outer corners and borders remain notably soft, requiring the photographer to stop down to f/2 for good border quality and f/2.8 for critical sharpness. Vignetting is also severe at f/1.4, exceeding 3EV in the corners and...

The Sigma 24mm f/1.4 DG DN Art lens is a highly versatile, well-constructed, and competitively priced wide-angle prime designed for mirrorless systems, delivering excellent to outstanding sharpness, particularly in the center. Weighing roughly 510g-520g, the lens features comprehensive weather sealing, a fast, near-silent AF motor, and professional controls including a de-clickable aperture ring, making it ideal for street and landscape photography. While offering impressive, high-end performance, the review highlights that edge sharpness is only "fair" when used wide-open at f/1.4, requiring users to stop down to f/2 or smaller for optimal corner performance. Additionally, the lens lacks optical image stabilization and relies on in-body camera systems, yet it earns a "Highly Recommended" rating for its outstanding price-to-performance ratio.

The DPReview TV review highlights the Sigma 24mm F1.4 DG DN Art as a redesigned, lightweight (510g) prime for mirrorless systems, offering excellent sharpness at f/2.8, robust build quality, and useful features like a de-clickable aperture ring and manual focus lock. While lauded for its handling and image quality, the lens shows significant focus breathing, noticeable wide-open vignetting, and rainbow flaring in harsh light. Additionally, it requires stopping down to f/2.8 for optimal corner performance in astrophotography, making it less specialized for that use than its 20mm counterpart.

The Sigma 24mm f/1.4 DG DN Art lens is identified as an exceptionally sharp prime offering outstanding contrast and center-frame resolution, making it ideal for low-light and astrophotography. Key advantages include its robust, weather-sealed build, customizable AFL button, de-clickable aperture ring, and a Manual Focus Lock (MFL) switch, all offered at a competitive price point. However, the lens lacks optical image stabilization and displays notable focus breathing, along with slight barrel distortion and corner softness when shooting wide open at f/1.4.
