Canon EF 24mm f/1.4L USM Reviews

Photozone reviews the Canon EF 24mm f/1.4L USM and writes;
“The center quality is surely very impressive throughout the tested aperture range but this isn’t quite as true for the borders which are soft at f/1.4 and the quality only increases slowly towards medium aperture settings. The distortion and CA figures are acceptable for such a lens but vignetting is way too pronounced on an APS-C DSLR even though the problem is only visible at f/1.4. The build quality is typical for a Canon L grade lens – simply superb.”
Rating: ★★★★☆

SLRLensreview reviews the Canon EF 24mm f/1.4L USM and writes;
“Canon EF 24mm f/1.4L USM continued to show quite impressive performance in the center, where it excelled pretty much throughout the tested aperture. But like with the APS-C camera, the lens continued to struggle around borders, especially at the widest aperture levels from f/1.4 through f/2. Border quality in this aperture range was rather mediocre.”
rating: N/A

The-digital-picture reviews the Canon EF 24mm f/1.4L USM and writes;
“The Canon EF 24mm f/1.4 L USM Lens is soft wide open, increasing in sharpness until very sharp at f/2.8. Corners are somewhat soft until stopped down some – becoming very sharp for a 24mm lens. Light fall-off is very noticeable at f/1.4, and, as usual, improves as the lens was stopped down. The 24 L exhibits noticeable amounts of CA.”

Canon EF 24mm f/1.4L USM Specifications

Canon EF Autofocus Lenses Canon s reputation for excellence in optics has been well established for years. And with the introduction of EF lenses for the EOS, it s only getting better. EF Lenses have the largest diameter mount of any 35mm camera, which not only strengthens the whole system, but permits optical innovations never before possible. L-Series lenses have better sharpness and contrast because Canon uses aspherical elements to eliminate spherical aberrations.

In addition, the L-Series telephotos use UD (Ultra-low Dispersion) glass to reduce chromatic aberration resulting in more accurate colors. A built-in Ultrasonic focusing Motor (indicated by USM) provides pro-quality AF speed with split-second accuracy. What makes this wide angle lens so unique is that it s the first EF lens to employ both a replicated aspherical element and a UD element to correct distortion and spherical aberrations and eliminate chromatic aberrations often experienced with wide angle lenses.

It also incorporates a floating construction for remarkably high resolution and distortion-free images at all distances within the entire focusing range (9.84 to infinity, even at maximum 1.4 aperture). Its rear focusing design maintains a constant lens length and the front doesn t rotate, making it easier to use special effects filters and the bayonet mount lens hood. This lens accepts 77mm filters.
