Canon EF 14mm F 2 8L II USM Análisis | 54 Datos comparados

The Canon EF 14mm f/2.8L II USM lens is described as a high-performance, rectilinear ultra-wide-angle prime that offers significant improvements in center sharpness, contrast, and flare resistance over its predecessor, featuring durable, weather-sealed L-series construction. Its 114-degree diagonal angle of view provides excellent image quality for landscape and architectural photography, backed by fast and silent Ring USM autofocus. Key compromises noted in the review include a prominent, bulging front element with a fixed lens hood that prevents the use of standard, circular screw-in filters. While the lens delivers exceptional center sharpness, it exhibits noticeable vignetting, corner softness, and astigmatism on full-frame cameras, making it a specialized, premium-priced tool.

The LensTip review of the Canon EF 14 mm f/2.8L USM II details an ultra-wide-angle lens that offers a massive 114.2-degree field of view on full-frame cameras. Optically, the lens performs admirably in the center of the frame, delivering very good image quality and sharpness. It features an ultrasonic USM autofocus motor that operates quickly and silently. The mechanical construction is robust, reflecting Canon’s high-end L-series standard with weather sealing and exceptional build quality. Furthermore, it handles longitudinal chromatic aberration exceptionally well and behaves predictably on smaller APS-C sensors, displaying minimal vignetting and low distortion. However, the lens suffers from serious optical flaws and a poor value proposition. The primary drawbacks include weak image quality on the edges of a full-frame sensor across a wide range of apertures, along with distinct lateral chromatic aberration, pronounced astigmatism, and noticeable coma in the full-frame corners. Full-frame users will also encounter a distinct -3.18% barrel distortion and significant vignetting at wider apertures. Because of its large, bulbous front element, attaching standard screw-on filters is impossible. Ultimately, LensTip concludes that the lens offers one...

The Canon EF 14mm f/2.8L II USM lens is a robust, weather-sealed optic with fast, quiet USM autofocus and a 20cm minimum focus distance, making it ideal for,,,wide-angle,photography. The review highlights its high-quality construction, light weight (645g), and excellent center sharpness, which peaks at f/4. Optically, the lens delivers low distortion, but edge sharpness only reaches "very good" levels, rather than excellent, and lacks a front filter thread due to its bulbous, fixed-hood design. While a rear gelatin filter holder is included, the inability to use standard filters on the front is a noted disadvantage for landscape shooters.

Ken Rockwell’s review highlights the Canon 14mm f/2.8 L II as a specialized, robust ultra-wide prime designed for full-frame DSLRs and 35mm film, offering a dramatic 114-degree view with improved, redesigned optics. The lens excels in corner sharpness and distortion control while providing instant USM autofocus, but is hindered by a high price, increased weight, and an inability to use standard screw-in filters.

The OpticalLimits (formerly PhotoZone) review by Klaus Schroiff provides an in-depth analysis of the Canon EF 14mm f/2.8 USM L II, an ultra-wide rectilinear prime lens designed for full-frame cameras. Built with professional-grade luxury in mind, it features a robust, weather-sealed metal body with a fixed petal-shaped hood and a smooth, constant-size focusing ring. Mechanically, it stands out for its fast, quiet ring-type USM autofocus system with full-time manual override. It utilizes an advanced optical layout consisting of 14 elements in 11 groups—including two aspherical and two ultra-low dispersion (UD) elements—which are housed under a bulb-like protruding front element designed to effectively reduce complex wide-angle aberrations. Optically, the review highlights several major strengths, or pros, notably its excellent sharpness at the center of the frame straight from f/2.8, very usable border and corner resolution, and highly controlled, minimal barrel distortion compared to wide-angle zoom options. Light fall-off (vignetting) is also reasonably well managed for a 114-degree ultra-wide lens, becoming non-intrusive starting around f/5.6. Conversely, the primary optical cons include a high amount of lateral chromatic aberrations (color shadowing) at image...

The Photo Review Australia review of the Canon EF 14mm f/2.8L II USM lens highlights its robust, weather-sealed build, fast ring-type USM autofocus, and excellent central sharpness. Weighing 645 grams, this professional prime provides a 114-degree field of view ideal for expansive scenes, offering smooth, full-time manual focus override and a 20 cm minimum focusing distance. Key limitations identified include a convex front element that prevents the use of standard screw-in filters, requiring inconvenient rear-mounted gelatin filters. Furthermore, the review notes significant corner distortion, peripheral vignetting, and lateral chromatic aberrations, particularly when shooting wide open on full-frame bodies.

The Canon EF 14mm f/2.8L II USM is an ultra-wide angle prime lens designed for full-frame cameras that offers massive optical upgrades over its predecessor. It features a completely redesigned optical layout containing two aspherical and two ultra-low dispersion glass elements, alongside a 6-blade aperture design. Built to professional L-series standards, the heavy 645-gram lens features robust metal construction with weather sealing, a built-in lens hood, a rear gelatin filter holder, and a quiet, fast Ultrasonic Motor (USM) for manual-override autofocusing. The lens presents a mix of excellent performance upgrades and traditional wide-angle optical limitations. On the positive side (pros), it delivers a dramatic leap in sharpness with negligible corner softness by f/5.6, drastically reduced chromatic aberration compared to version I, minimal barrel distortion at just 0.25% to 0.5%, and an improved macro magnification ratio of 0.15x. On the downside (cons), full-frame users will experience extreme vignetting wide open at f/2.8, reaching 1.9 stops darker in the corners, which never completely drops below a half-stop even at f/8. Additionally, it lacks a front filter ring due to its bulbous element...

The Canon EF 14mm f/2.8L II USM is an ultra-wide, weather-sealed L-series lens designed for professionals, offering a fast f/2.8 aperture for low-light performance and silent, high-speed autofocus via a USM motor. Its strengths include robust construction and superior depth-of-field control. However, the lens is a significant financial investment priced around £1850, and its optical design suffers from pronounced barrel distortion and vignetting at wider apertures. Furthermore, the bulbous front element prevents the use of traditional screw-on filters, requiring specialized, often costly alternatives.
