Sigma 20mm F 1 4 DG DN Recensie | 54 Gegevens vergelijking

The lens possesses notable strengths and minor drawbacks. Its main pros include an ultra-bright F1.4 aperture, impeccable edge-to-edge optical performance wide open, robust weather protection, and astro-centric design perks like a flared barrel for lens heating wraps and a focus lock feature. Conversely, its cons center around a heavy and bulky design (weighing 1.4 pounds and taking 82mm filters), making it less ideal for hikers, gimbals, or drones compared to lighter competitors like the Sony FE 20mm F1.8 G. Additionally, videographers may find its non-linear manual focus response on Sony bodies frustrating, and it exhibits highly visible focus breathing along with mushy sunstar lines at narrow apertures. Ultimately, it stands out as a premier choice for wide-angle specialists who require maximum low-light gathering capability.

The Sigma 20mm F1.4 DG DN ART is a native mirrorless lens that improves significantly over its bulky, adapted DSLR predecessor, offering a body that is 30mm shorter and over 400g lighter. Clocking in at 630g with dimensions of 88mm x 113.2mm, it delivers incredible optical performance even at F1.4 with a dramatically flatter focus curve and vastly sharper corners than the older model. The lens is packed with professional features, including a robust manual aperture ring with click/declick switches, an aperture lock, an AF/MF switch, a focus hold button, and a unique manual focus lock button designed for astrophotographers. Autofocus is powered by a fast, silent, and highly accurate stepping motor (STM) that provides instantaneous focus pulls for photo and video. Furthermore, it incorporates thorough weather sealing, a front lip to hold lens heaters, and dual filter solutions supporting standard 82mm front screw-in filters alongside a rear filter holder. Optically, the lens shines with outstanding resolution and high contrast across the frame from wide open, accompanied by exceptionally low barrel distortion and excellent flare resistance. Chromatic aberrations are kept...

The Sigma 20mm f1.4 DG DN Art lens is a highly capable, professional-grade ultra-wide-angle lens designed for L-mount camera systems like the Panasonic Lumix S5. Despite its fast f1.4 aperture, the lens maintains a relatively compact and lightweight footprint, weighing 635g. It boasts a robust, weather-sealed build using aluminum and Thermally Stable Composite materials. Notable physical features include a de-clickable and lockable aperture ring, a manual focus lock switch, a front 82mm filter thread, and a unique rear filter holder that can be used simultaneously with front filters. Autofocusing is driven by a fast, silent, and highly accurate stepping motor, supporting a close minimum focus distance of 23cm. Optically, the lens delivers reference-level performance with incredible sharpness across the frame even when shooting wide open at f1.4. Key pros highlighted in the review include its superb image quality, smooth bokeh transitions, high resistance to flare, and an affordable retail price of $899. On the downside, the lens exhibits some vignetting at f1.4, though it clears up by f4. Additionally, the reviewer notes that for photographers who do not strictly need...

The Sigma 20mm f/1.4 DG DN Art lens delivers exceptional optical performance, proving to be a highly effective wide-angle prime for professional mirrorless photographers. The reviewer praised its stunning corner-to-corner sharpness, beautiful depth of field, and fast, accurate autofocus system. Additionally, the lens features a dust- and splash-resistant weather-sealed build, an 11-blade rounded diaphragm, and an aperture ring equipped with click and lock switches. It exhibits excellent image control, showing little to no ghosting, flaring, or chromatic aberrations, alongside very well-managed distortion and minor vignetting. The major drawback of this lens is its complete lack of built-in image stabilization, which forces it to rely entirely on a camera body's internal stabilization features. While this presents no issues for modern full-frame mirrorless bodies, it remains an important consideration for users of older camera bodies with less effective stabilization systems. Furthermore, while the physical design includes a generous manual focus ring, an AFL button, and a manual focus lock switch, the lens is notably large. Despite these constraints, the review concludes that the lens has virtually no optical points of failure, earning...

The Sigma 20mm f/1.4 DG DN Art lens for mirrorless systems is described as a top-tier performer, earning the "Editor's Choice" award for outstanding sharpness, low chromatic aberration, and well-controlled distortion. The lens features dust and splashproof construction, fast, silent autofocus, and specialized features like a Manual Focus Lock (MFL) switch, plus excellent flare resistance. Pros include high-quality build and imaging, while cons are limited to visible vignetting at f/1.4 and a lack of internal image stabilization, relying on in-body systems (IBIS). Overall, it is praised for its high price-to-performance ratio, making it an excellent choice for astrophotography and wide-angle photography.

The Sigma 20mm F1.4 DG DN Art lens is highlighted as a high-performing, weather-sealed, and physically robust prime lens designed for low-light situations, with exceptional optical sharpness at infinity making it ideal for astrophotography. Specialized features for night photography include a Manual Focus Lock (MFL) switch and a physical aperture ring with a click toggle. However, the lens lacks optical image stabilization and is relatively heavy and bulky due to its complex 17-element optical design, which may limit its suitability for casual, lightweight travel. The lens represents a significant commitment in size for a wide-angle prime, prioritizing top-tier, edge-to-edge resolution.

The LensTip Sigma A 20 mm f/1.4 DG DN review concludes that this mirrorless-dedicated lens is an optically impressive tool featuring very solid, weather-sealed mechanical construction and unique ultra-wide parameters. The primary pros highlighted by the reviewers include very good image quality in the frame centre, good resolution at the edge of the APS-C sensor, and sensible quality on full-frame edges. Additionally, it features excellent coma correction, negligible lateral chromatic aberration, slight astigmatism, snappy and reliable autofocus performance, and the versatile ability to simultaneously support both standard 82mm front screw-on filters and rear gelatin filters. On the downside, the cons identified in the review focus on a few performance compromises typical for an ultra-wide, ultra-fast f/1.4 optical design. The reviewers noted huge vignetting on full frame that reaches up to −3.68 EV (72% light loss) at the maximum relative aperture and remains visible even when stopped down. While ghosting and flare resistance are significantly improved over its DSLR predecessor, the lens can still register flares when the sun is located far outside the frame. Furthermore, the lens exhibits a surprising...

The Sigma 20mm F1.4 DG DN Art lens is an Editors' Choice-winning, ultra-wide prime for mirrorless cameras, featuring outstanding optical sharpness, fast focus, and excellent coma performance for astrophotography. It supports 82mm front filters, includes a manual focus lock switch for night shoots, and features a robust, weather-sealed construction. Conversely, the lens is heavy at 1.4 pounds and 4.5 by 3.5 inches, making it less ideal for gimbal use compared to lighter alternatives like the Sony FE 20mm F1.8 G. While sharp, it exhibits significant barrel distortion and heavy vignetting in RAW files when uncorrected, and it lacks true macro focusing capabilities.

The Sigma 20mm f/1.4 DG DN Art lens is praised as a high-performance, weather-sealed, wide-angle lens ideal for architecture and landscape photography, featuring excellent sharpness, low distortion, and minimal chromatic aberration.
