Sigma 12 24mm F4 5 5 6 DG HSM II Recensione | 54 Dati a confronto

The LensTip review concludes that the Sigma 12-24 mm f/4.5-5.6 II DG HSM is a highly unique, extreme full-frame ultra-wide zoom lens that offers an impressive 122-degree field of view at its shortest focal length. A major highlight of the lens is its excellent build quality, featuring a compact, solidly made casing along with a smooth, well-damped zoom and manual focusing ring. In terms of performance, the lens provides excellent image quality in the frame centre, decently corrected coma, and very low astigmatism. Furthermore, the lens benefits from a silent, quick, and highly accurate ultrasonic Hyper Sonic Motor (HSM) autofocus drive, alongside sensibly low geometric distortion considering its extreme angles of view. Despite its advantages, the review highlights notable drawbacks regarding the lens's optical limits. Its built-in petal-type hood is too short to prevent side light, leading to significant ghosting and flare issues across all apertures and focal lengths. Additionally, chromatic aberration remains a visible issue, particularly reaching its highest level at the 12mm focal length. The lens also suffers from a narrow, variable maximum aperture of f/4.5-5.6, making manual...

The Sigma 12-24mm f/4.5-5.6 II DG HSM is an ultra-wide-angle zoom lens designed for full-frame cameras, offering an exceptionally wide field of view that inspires immense creative potential. It features solid, weather-sealed construction with a matte black finish, a metal mount, and a fast, exceptionally quiet Hyper Sonic Motor (HSM) autofocus system. Optically, the lens delivers very high resolution in both the center and along the edges when stopped down, while successfully minimizing flare, ghosting, and lateral chromatic aberration thanks to specialized FLD and SLD glass elements. However, the lens's extreme design introduces notable drawbacks, including clear geometric distortion that shifts from barrel-shaped at 12mm to pincushion at 24mm. Due to its large field of view, it suffers from heavy natural and optical vignetting that never completely disappears even at f/11, though this can be easily corrected using Lightroom profile adjustments. Additionally, its prominent convex front element and fixed petal-type lens hood completely prevent the use of traditional screw-on filters, and it lacks built-in image stabilization.

In his December 2012 review, Frank Doorhof praises the Sigma 12-24mm lens for its unmatched, compact 12mm-24mm perspective on full-frame cameras, highlighting its impressive color rendition, high sharpness, and budget-friendly price point. The lens is lauded for being noticeably more compact than older alternatives like the Sigma 15-30mm, offering a unique, extreme wide-angle, distortion-controllable option, even for APS-C users. However, the review notes minor chromatic aberration, which is described as easily correctable in post-processing. A significant limitation is the bulbous front element, which prevents the use of standard, front-mounted, screw-on filters.

The Sigma 12-24mm f/4.5-5.6 DG II HSM lens is highlighted by The Digital Picture for offering the widest rectilinear focal length available for full-frame DSLRs, providing an incredibly vast angle of view with excellent center sharpness and high contrast. Key advantages include its robust build, quick and quiet HSM autofocus, and superior FLD glass elements, making it ideal for specialized architecture and landscape photography. However, the lens features slow maximum apertures, leading to poor performance in low light, and suffers from significant soft-focus and lateral chromatic aberration in the extreme corners. Furthermore, the bulbous front element prevents the use of standard screw-on filters, limiting its versatility.

The LensVid review highlights the Sigma 12-24mm F4.5-5.6 II DG HSM as a highly unique, ultra-wide zoom lens that served as one of the widest full-frame options on the market until the release of the Canon 11-24mm f/4. Though it predates Sigma's premium "ART" line, it delivers a massive field of view that is particularly valuable for Nikon users or budget-conscious full-frame photographers who cannot afford Canon's $2,900 alternative. Priced at $950, it is framed as a massive bargain that provides decent overall performance on full-frame systems, making it an interesting dual-purpose choice if you bounce between APS-C and full-frame bodies. The evaluation outlines distinct performance trade-offs, showcasing clear pros and cons in image quality. On the positive side (pros), the lens is impressively sharp in the center of the frame even when shot wide open, features remarkably low and manageable barrel distortion at the extreme 12mm end, and peripheral darkening and corner sharpness noticeably improve when stopping down the aperture. Conversely (cons), the lens suffers from weaker corner sharpness when wide open, exhibits noticeable color fringing along the edges...

The personal review of the Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM II lens on Caught in Pixels highlights its performance as an ultra-wide rectilinear zoom option for full-frame cameras. A major pro is its tack-sharp centre resolution, providing impressive clarity in the middle of the frame even when shot wide open. Additionally, it delivers an immensely wide 122° angle of view at 12mm, making it a highly capable tool for capturing expansive landscapes and tight architectural spaces without a fish-eye look. YouTube · Conversely, the reviewer points out several notable optical compromises. A distinct con is the softness in the extreme corners, which only sharpens up as you crop closer to the center. The lens is also quite slow with a variable maximum aperture of f/4.5 at 12mm that drops to f/5.6 at 24mm. This slower aperture forces the photographer to increase ISO or utilize longer shutter speeds in low-light environments, limiting its versatility indoors or after dark.

The Sigma AF 12-24mm f/4.5-5.6 HSM DG II is a full-format ultra-wide zoom lens tested on a Canon APS-C crop camera, making it an appealing option for photographers planning a future transition to full-frame systems. On an APS-C body, it delivers a full-frame equivalent focal length of 19-38mm. The lens boasts a very high build quality with a precise, tightly assembled mix of metal and plastic parts, a metal mount, and a fast, nearly silent Hypersonic Motor (HSM) autofocus mechanism. Its physical length remains constant during zooming and focusing, and it features an upgraded optical design containing four FLD glass elements to boost performance over its predecessor. However, the lens has several notable drawbacks that users must consider before purchasing. A primary disadvantage is its bulky design, which requires a non-detachable petal-shaped lens hood to protect a vulnerable, bulb-like front element. This physical design means regular filters cannot be easily used; attaching a filter to the specialized two-part lens cap assembly causes heavy vignetting at wide focal lengths. Additionally, buyers must pay a higher price premium for the larger full-frame...

The Sigma 12-24mm F4.5-5.6 EX DG HSM II (Canon mount) is an ultra-wide-angle zoom lens released in February 2011, designed to deliver expansive perspectives on both full-frame and APS-C bodies. When tested by DXOMARK, the lens achieved an overall DXOMARK score of 9, performing at its best at the 12mm focal length with a maximum aperture of f/4.5. Its standout performance benefit is a major upgrade in chromatic aberration control over its predecessor, which is driven by the integration of premium FLD (“F” low dispersion) glass elements. This specific material mimics fluorite glass to lower the refractive index and significantly suppress color fringing, keeping the center of the image particularly clean and sharp at the widest 12mm setting. Despite these optical improvements, the lens struggles with several notable performance limitations under technical scrutiny. The primary drawback is its low sharpness score, yielding just 6 P-Mpix, which indicates a softer overall image reproduction. Additionally, its light transmission is rated at a restrictive 5.8 TStop, which compromises low-light efficiency beyond its already dark variable physical aperture. On the upside, the lens keeps...
