Sigma 14mm F 1 8 DG HSM Art Análisis | 54 Datos comparados

The Photography Life review highlights the Sigma 14mm f/1.8 DG HSM Art as an exceptional, durable lens designed for landscape and astrophotography, boasting superb central sharpness and a fast f/1.8 aperture. While praised for its performance, the lens features a bulbous front element that prevents standard filters, is physically heavy (over 1,100g), and shows noticeable corner vignetting and coma at maximum aperture.

The Sigma 14mm F1.8 DG HSM Art is a specialized ultra-wide prime lens praised for its extremely bright f/1.8 aperture and exceptional sharpness, making it a premier choice for astrophotography and low-light architectural work. Built with a solid metal and polycarbonate barrel, it features dust and splash protection and a fluorine coating to repel oil and fingerprints. In performance tests, it delivered outstanding resolution, peaking at f/5.6 and f/8, though it suffers from soft edges and corners at its widest apertures and a meager 1:9.8 macro magnification. Despite its high-end optics, the lens has several physical and technical drawbacks, most notably its large, bulbous front element which prevents the use of standard front filters. Users will also encounter visible barrel distortion of approximately 4.3% and significant corner dimming (vignetting) of up to 4 stops when shooting wide open. Furthermore, the lens is physically demanding, weighing 2.5 pounds and lacking internal optical stabilization, which may limit its appeal as a general-purpose tool compared to more versatile ultra-wide zooms.

in english language, be very specific, mention pros and cons insideSearching The Dustin Abbott review of the Sigma 14mm f/1.8 DG HSM ArtGo to product viewer dialogue for this item. lens details a ground-breaking, ultra-wide-angle prime engineered with a unique optical formula. A major pro highlighted in the text is its outstanding sharpness across the center of the frame, even when shooting wide open at f/1.8, combined with a robust, modern design, a 10.63-inch minimum focus distance, and an effective Hyper Sonic Motor (HSM). However, the review outlines several notable cons and trade-offs, including a very low 0.10x maximum magnification ratio and the inability to use standard screw-on filters due to the bulbous front element. Furthermore, the lens is heavy, weighing over 1.1 kilograms, and exhibits some comatic distortion and softer extreme corners when shot wide open.

The Sigma 14mm f/1.8 DG HSM Art is a groundbreaking ultra-wide-angle lens, being the first full-frame optic to offer a fast f/1.8 maximum aperture at this focal length. Its robust construction features professional-grade weather sealing and a mix of metal and Thermally Stable Composite materials. Optically, it excels with impressive center sharpness even when shot wide open, and stopping down to f/8.0 provides consistent high-end performance across the entire frame. This combination of a 114.2° field of view and light-gathering speed makes it a premier choice for astrophotography, as it displays minimal comatic aberration in all but the extreme corners. Despite its high performance, the lens has notable drawbacks, primarily its substantial weight of over 2.5 pounds (1,170g), which makes it front-heavy and difficult to balance on smaller camera bodies. Users will encounter significant vignetting at f/1.8, though this improves by f/2.8, and may occasionally notice purple fringing or chromatic aberrations around high-contrast edges. Furthermore, the bulbous front element lacks a filter thread, necessitating specialized adapters for landscape photographers who use filters. While the autofocus is reliable and smooth, the...

The Sigma 14mm f1.8 DG HSM Art is a highly durable, high-performance ultra-wide-angle lens constructed from Thermally Stable Composite with a robust brass mount, making it dust and splash-resistant. Designed for specialized low-light environments like astrophotography, architectural work, and weddings, it features a fast f1.8 aperture that reduces exposure times for starry skies, along with a quick Hyper Sonic Motor (HSM) autofocus system and a unique 10.63-inch minimum focus distance. Optically, the lens delivers superb image quality and excellent center sharpness when shot wide open, achieving its peak edge-to-edge detail between f5.6 and f8. The review highlights several distinct pros and cons regarding the lens's design and optical performance. Its main advantages include an incredibly solid, weather-sealed build, fast and highly accurate autofocus, excellent overall image resolution, and availability across multiple camera systems, including L, Sony E, Canon EF, Nikon F, and Sigma SA mounts. On the downside, the lens is heavy and bulky at 2.6 lbs, and its massive, bulbous front element completely prevents the attachment of standard front filters. Optically, users must contend with noticeable vignetting at wider...

The DPReview article highlights the Sigma 14mm F1.8 DG HSM Art lens as a groundbreaking tool for night sky photography, emphasizing its f/1.8 aperture as a 1.3 EV advantage over standard f/2.8 lenses, allowing for significantly shorter exposures. Key pros include capturing clean, high-detail images with minimal noise or using fast shutter speeds to freeze celestial movement. Conversely, the review notes that the lens's extreme speed leads to trade-offs, specifically noticeable vignetting and comatic aberration when shooting wide open. Additional cons include its large, heavy, and cumbersome form factor, along with potential edge-softness issues that may require post-processing to correct.

The Sigma 14mm f/1.8 DG HSM Art lens is highlighted as the world's first full-frame f/1.8 ultra-wide-angle lens, offering exceptional optical performance and a fast aperture ideal for low-light scenarios. While it provides a 114-degree field of view and balances well on cameras, it is noted for being heavy and bulky, with minor corner softness and chromatic aberration observed. Key drawbacks include the lens's significant weight and size, along with practical competition from more versatile 14-24mm zoom lenses, which may be preferred over this fixed prime, according to the review. The lens is recognized as a specialized tool that delivers unique, high-quality results for photographers requiring an extremely fast ultra-wide optic.

The Sigma 14mm f/1.8 Art lens is a groundbreaking, ultra-wide prime that delivers a distinctively punchy, high-contrast, and vibrant look straight out of the camera. Its biggest selling point is its exceptional center sharpness and the massive light-gathering advantage of the f/1.8 aperture, which offers superior low-light performance and unique creative subject separation compared to traditional f/2.8 zoom alternatives. Additionally, it features an elegant brushed aluminum finish, very low barrel distortion, and beautiful sunbursts with a warm, eye-catching glow when shooting directly into the sun. However, these envelope-pushing optics come with significant trade-offs in size and mobility. The lens is incredibly heavy and bulky, making it less than ideal for lightweight hiking or casual travel. Optically, users will notice some softness in the extreme corners when shooting wide open at f/1.8, alongside a natural corner vignette. The autofocus system is generally snappy but can occasionally hunt in tough backlit conditions, and the lack of a zoom range requires relying on camera megapixels to crop in when a 24mm field of view is needed.

The Sigma 14mm f/1.8 DG HSM Art is praised as a groundbreaking, handcrafted ultra-wide-angle lens tailored for high-megapixel DSLR sensors like the Canon 5DS/R. The reviewer notes several prominent advantages, emphasizing that its exceptionally fast f/1.8 aperture produces a smooth, creamy background bokeh while keeping foreground subjects razor-sharp. It delivers remarkable edge-to-edge sharpness and resolution across the entire frame without the "mushiness" common to other super-wide lenses. Furthermore, its advanced optical structure minimizes chromatic aberration and distortion, resulting in excellent rectilinear control that keeps straight architectural lines precise and true. Additional benefits include a dust- and splash-proof build and a consistent, pleasing color palette, making it highly versatile for astrophotography, landscapes, and interiors. On the downside, the review explicitly highlights that the lens is not lightweight. Achieving the fast f/1.8 aperture requires a massive amount of physical glass elements, adding noticeable bulk and physical strain during handling. There is also a slight learning curve mentioned, as it took the reviewer a few dozen exposures to get an accurate feel for the dramatic forced perspective and dramatic movement that comes with...
