Canon released today two fast lenses; one is latest professional L-series prime lens: the EF 85mm f/1.2 II USM and the other is the EF-S 17-55mm f/2.8 IS USM.
With the widest aperture of any lens in the current EF range, the EF 85mm f/1.2 II USM becomes Canon's definitive portraiture lens, offering extremely fine control over depth of field and consummate low light performance.
As with all L-series lenses, the EF 85mm f/1.2 II USM incorporates the very finest standards of precision optics.
In addition to optimized lens shaping to reduce reflections and the use of anti-reflective material inside the lens barrel, the EF 85mm f/1.2 II USM employs Canon's patented Super Spectra lens element coatings. These suppress flare and ghosting, more prone to occur with digital cameras due to reflection off the image sensor. By increasing
light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural color balance.
The EF 85mm f/1.2 II USM transmits distance information to the E-TTL II flash system of all current model digital EOS cameras, improving flash exposure metering when used in conjunction with Canon's range of EX Speedlite flash units.
The EF 85mm f/1.2 II USM comes with a cylindrical lens hood and lens pouch.
With image quality and construction approaching that of Canon's renowned professional lenses, the EF-S 17-55mm f/2.8 IS USM becomes the fastest standard focal length zoom for EF-S mount cameras such as
the new EOS 30D.
Combining constant f/2.8 aperture throughout the zoom range with Canon's latest 3-stop Image Stabilizer, it delivers outstanding wide angle performance and framing flexibility in low light conditions. Specialist optics such as UD glass and aspherical elements help deliver exceptional clarity, sharpness, contrast and colour accuracy.
The lens fits exclusively on those EOS cameras with an EF-S lens mount, the new EOS 30D, EOS 350D, and earlier EOS 20D and 300D models. The 1.6x multiplication effect of these cameras' APS-C size sensor gives the lens an effective focal length of approximately 27-88mm.
To improve image clarity over the total image area, two Ultra-Low Dispersion glass (UD) elements are employed to eliminate secondary chromatic aberrations that otherwise reduce sharpness and introduce color fringing. To ensure crisp, high contrast from one corner of the frame to the other, two aspherical lens elements have been introduced to avoid spherical aberrations that can soften images, especially at wider apertures.
When used in conjunction with Canon's range of EX Speedlite flash units and the internal flash of the EOS 350D, EOS 20D and new EOS 30D, the lens passes distance information to the E-TTL II flash algorithm to improve flash exposure metering.
An optional lens hood, made exclusively for the EF-S 17-55mm f/2.8 IS USM, and pouch are available.
The EF 85mm f/1.2 II USM has a price tag of approximately $2100 and the EF-S 17-55mm f/2.8 IS USM costs $1150.
