Canon strengthens its line-up of EF-series lenses with the introduction of a new fast aperture prime lens: the EF 24mm f1.4L II USM.

 Replacing the EF 24mm f1.4L USM, the EF 24mm f1.4L II USM has been completely redesigned to provide an exacting partner lens to Canon’s new EOS digital SLRs, the EOS 50D and the EOS 5D MKII.

 The EF 24mm f1.4L II USM offers:

• Fast f/1.4 aperture
• Aspherical and UD lens elements for correction of chromatic aberration
• Sub Wavelength structure Coating (SWC) to dramatically reduce ghosting and flare
• Circular aperture for creative blurred highlights
• USM for full-time manual focus
• Lead-free glass (RoHS compliance)
• Lens hood and pouch supplied

Superior image performance

Featuring a 13-element, 10-group lens, the EF 24mm f1.4L II USM is designed to achieve the highest standards of image quality. Two high-precision GMo aspheric lenses are employed to correct various forms of aberration such as curvature of field and distortion, with a floating mechanism ensuring crisp corner-to-corner detail throughout the focal range. In addition, two UD lenses reduce the chromatic aberration common in wide-angle lenses.

 A fast, ultra-large maximum aperture of f1.4 delivers excellent low-light performance, with the circular aperture offering the potential for creative out-of-focus highlights. A focal length of 24mm and a USM focus motor providing full-time manual focus also make the EF 24mm f1.4L II USM ideal for situations where a wide-angle, high-performance lens is required.

Advanced lens coating

Reflections off a digital camera’s image sensor can compromise images with ghosting and flare. To help reduce this, the inside of EF 24mm f1.4L II USM’s front element is treated with Canon’s new Sub Wavelength structure Coating. Developed specifically to work with Canon optics, this anti-reflective coating helps reduce flare and ghosting - for consistently crisp, undistorted images.

Robust build quality

Weighing just 650g, the EF 24mm f1.4L II USM is designed to withstand the rigours of even the most testing shooting environment – with Canon’s advanced weather and dust sealing making it the perfect choice for photojournalists and landscape photographers.
