Canon EF 24 70mm F 4L IS USM Análisis | 54 Datos comparados

The Canon EF 24-70mm f/4L IS USM is a standard L-series zoom lens that offers a modest overall DxOMark score of 19 when tested on an EOS 5D Mark II. On the positive side, the lens delivers an exceptional transmission performance that perfectly matches its f/4 maximum aperture with virtually zero light loss. It also features minimal absolute distortion (0.2%) with only slight barrel distortion at 24mm, highly controlled chromatic aberration at 8µm, and a fast, quiet UltraSonic Motor (USM) for autofocus. Furthermore, its advanced Hybrid Image Stabilizer provides up to 4 stops of compensation during normal shooting and up to 2.5 stops during macro work. Conversely, the lens falls short in sharpness and frame homogeneity, achieving a sharpness rating of only 13 P-Mpix. It suffers from a rapid fall-off in sharpness from the center to the edges at maximum aperture across all focal lengths, with the worst degradation occurring at 50mm f/4. Heavy vignetting is another significant drawback, reaching a harsh -1.3EV corner light loss at 24mm f/4; corner shading only truly disappears when zoomed to 70mm and stopped...

The Canon EF 24-70mm f/4L IS USM is a versatile, professional-grade standard zoom featuring excellent center sharpness at f/4 and a capable 0.7x macro mode. It boasts robust weather-sealed construction, fast USM autofocus, and effective 4-stop image stabilization for handheld shooting. Conversely, the lens shows a minor dip in sharpness at 35-50mm, noticeable corner vignetting at 24mm f/4, and utilizes a telescoping design, notes The-Digital-Picture.com. While highly functional, its f/4 constant maximum aperture limits low-light capability compared to f/2.8 alternatives.

The Canon EF 24-70 mm f/4L IS USM is an optically outstanding zoom lens that initially surprised the market due to its narrower focal range and higher launch price compared to the existing 24-105mm f/4L alternative. According to the comprehensive testing by LensTip, the lens delivers sensational, prime-like image resolution in the frame center (especially at the 24mm wide end) along with excellent edge-of-frame sharpness across full-frame sensors, outperforming both the 24-105mm f/4L and more expensive f/2.8 models in edge resolution. Its premium mechanical construction features a solid, high-quality casing, an efficient built-in optical image stabilization system, and a silent, fast, and highly accurate ultrasonic autofocus motor. Additionally, it provides great value through near-perfect correction of longitudinal and lateral chromatic aberrations, very low astigmatism, almost invisible vignetting on APS-C sensors, and a highly versatile built-in macro functionality. Despite its strong overall performance, the LensTip review highlights a few notable drawbacks. The lens exhibits weak performance against bright backlighting, leaving it susceptible to flares, and its out-of-focus bokeh rendering is slightly marred by distinct outer rims and faint "onion ring" textures...

In terms of image quality, the lens delivers pleasing contrast and sharpness throughout its zoom range, aided by two aspherical and two Ultra-low Dispersion (UD) elements. However, it does come with a few notable cons, such as severe vignetting when shooting at wide apertures. Because the lens has a constant f/4 aperture, it is a full stop slower than f/2.8 alternatives, resulting in bokeh that is not quite as smooth and slightly limited performance in low-light environments. Despite these drawbacks, the review concludes that its lighter weight, lower price point, and advanced macro capabilities make it an excellent standalone choice rather than just a budget substitute.

The Canon EF 24-70mm f/4L IS USM lens is a robust, well-constructed addition to Canon’s advanced L-series that functions as a lightweight alternative to heavier zooms, weighing only 600 grams. When tested on an APS-C crop-sensor camera like the Canon 650D, it delivers an equivalent focal length of 38-112mm, making it highly suitable for landscape, street, and holiday photography. The lens delivers high sharpness starting at its maximum aperture across the frame, though the edges and corners lag slightly behind the center sharpness. One of its standout features is the built-in Hybrid Image Stabilization system, which corrects for angular and tilting movements to achieve a tested profit of 3 to 4 stops. Additionally, the inclusion of a dedicated macro button allows photographers to achieve a maximum magnification ratio of 0.7x, minimizing the need to carry a specialized macro lens. The review highlights several core pros and cons for buyers to consider. On the positive side, the lens boasts high image quality, dust- and moisture-proof weather sealing, and an upgraded image stabilization system that outperforms the popular Canon 24-105mm f/4 IS....

The Canon EF 24-70mm f/4L IS USM is a well-built, weather-sealed mid-range zoom lens praised for its high sharpness across all focal lengths, light and compact design, and effective 4-stop Image Stabilization (IS) system. Its most standout feature is a dedicated macro mode that achieves a 0.7x maximum magnification and utilizes a specialized Hybrid IS system to correct both angular and shift movements at close range. Optically, the lens exhibits well-controlled chromatic aberration, minimal distortion in the mid-zoom range, and includes internal focusing so the lens length remains constant while focusing. This combination makes it a highly versatile, lower-cost alternative to the heavier f/2.8L version. However, the review highlights several distinct drawbacks, most notably significant vignetting at 24mm where the corners measure about 2 stops darker than the center at full aperture. It also displays -2.5% barrel distortion at the.7% pincushion distortion at 70mm. While macro performance is strong, the working distance from the front of the lens to the subject is a very tight 3cm (1.2 inches) at maximum magnification, which complicates lighting and may disturb live subjects. Additionally,...

The Canon EF 24-70mm f/4L IS USM lens is a versatile, high-performance standard zoom for full-frame cameras, offering excellent center sharpness, fast ring-type ultrasonic autofocus, and effective 4-stop image stabilization. A standout feature is the dedicated macro mode at 70mm, providing a 0.7x maximum magnification and incorporating Hybrid IS for enhanced stability. On the downside, the lens suffers from severe vignetting at wide apertures, is highly prone to flare without the hood, and produces less-than-ideal bokeh. Additionally, live view autofocus is notably slow, and a minor focus shift occurs when zooming, alongside a high price point compared to competitors.
