Sigma 24 70mm F 2 8 DG DN Art Recensione | 54 Dati a confronto

The DPReview field review characterizes the Sigma 24-70mm F2.8 DG DN Art as a high-value, professional-grade zoom offering exceptional center sharpness across its range, even at wide-open F2.8. Key strengths include robust weather-sealing, durable construction with a brass bayonet, and advanced coatings that minimize flare. Conversely, the lens exhibits noticeable corner softness at 24mm and 70mm, requiring users to stop down to F5.6 to achieve uniform sharpness. Furthermore, the review identifies significant vignetting and complex distortion at the 24mm position, coupled with a relatively heavy, bulky design.

The Sigma 24-70mm F2.8 DG DN Art is a highly competent standard zoom lens for Sony mirrorless cameras that delivers pro-grade build quality, robust weather sealing with eight distinct seal points, and an excellent price-to-performance ratio. Priced at $1,099 USD, it directly disrupts the market by matching the physical features and optical performance of the $2,198 Sony G Master lens at half the cost. It features an upgraded exterior design complete with a rubberized focus ring, an AF/MF switch, a customizable focus hold button, and a zoom lock mechanism. Autofocus performance is exceptionally fast, silent, and reliable, showing excellent tracking accuracy with both human and pet Eye AF, requiring zero calibration out of the box. Optically, the lens provides strong, consistent sharpness, rich contrast, and pleasingly soft bokeh across the entire zoom range, easily outperforming competitors like the Tamron 28-75mm at the 70mm telephoto end. However, it does suffer from a few notable drawbacks, most significantly its poor flare resistance, which leaves images highly vulnerable to veiling and ghosting when shooting directly into the sun. It also exhibits pronounced barrel...

The Sigma 24-70mm f2.8 DG DN Art lens for L-mount is an exceptionally well-built, professional-grade zoom lens designed specifically for mirrorless systems, making it 200 grams lighter than its DSLR predecessor. Constructed from metal and Thermally Stable Composite (TSC) material, the lens features full weather and dust sealing throughout its body, an 82mm filter thread, and handy physical controls including an AFL button, AF/MF switch, and a zoom lock switch. Its stepping motor delivers fast, accurate, and near-silent autofocus that performs seamlessly with face-detection tracking. Additionally, it offers impressive close-up capabilities, boasting a minimum focusing distance of 7.1 inches at the wide end. Optically, the lens delivers outstanding sharpness across the zoom range, resolving excellent detail even when tested on a high-resolution 61-megapixel sensor. A major standout feature is its 11-rounded blade diaphragm, which produces buttery smooth, creamy bokeh that is highly unusual for a standard zoom lens. However, the reviewer noted minor cons, including slight distortion and visible vignetting when shooting wide open at f/2.8, though both are standard for this type of lens and reduce significantly by f/4....

The Sigma 24-70mm F2.8 DG DN Art is a high-performance standard zoom for mirrorless cameras, delivering exceptional sharpness, fast autofocus, and close-focus capabilities (7.1 inches) while offering significant cost savings compared to brand-name alternatives. The lens features a robust, weather-sealed design suitable for professional use. However, the lens exhibits notable limitations, including significant field curvature at 24mm, a drop in contrast at 70mm near the minimum focus distance, and heavy vignetting in RAW files that requires software correction. Users should expect to stop down to f/4–f/5.6 for maximum crispness in certain scenarios.

The Sigma 24-70mm f/2.8 DG DN Art lens is highly praised by The-Digital-Picture as a top-tier, versatile, and high-value standard zoom designed for Sony E and Leica/Panasonic L-mount full-frame mirrorless cameras. Key advantages include exceptional center sharpness, a robust weather-sealed construction, fast autofocus, and excellent close-focusing macro capability at a competitive price point. Conversely, the lens displays some peripheral vignetting at 24mm, barrel distortion, and a slight drop in edge sharpness at 70mm, while lacking built-in optical stabilization. Furthermore, it features a telescoping zoom design and carries a weight that some might find significant for all-day shooting.
