Pre-PMA 2006: Canon has today announced the 'Mark II' version of its (monster) professional EF 85 mm F1.2 L II lens. This new version includes improvements to auto focus speed and communication of distance information for use with the E-TTL II flash metering algorithm. This lens should be available in March for approx. $2100.
Press Release:
f/1.2 ideal for portraits and low light
Amstelveen, The Netherlands,
21 February, 2006: Canon today releases its latest professional L-series prime lens:
the exceptionally fast
EF 85mm f/1.2 II USM. With the widest aperture of any lens in the current EF
range, the new model becomes Canon&s definitive portraiture lens, offering
extremely fine control over depth of field and consummate low light
performance. With vastly improved auto focus speed, the lens replaces the
popular EF&85mm&f/1.2L&USM. As with all L-series lenses, the EF
85mm f/1.2 II USM incorporates the very finest standards of precision optics.
EF 85mm f/1.2 II USM - &2,049
The EF 85mm f/1.2 II USM features:
finest standards of image quality
Ultrasonic Motor (USM) for fast and near silent auto focus
electronic manual focus override
Spectra coatings and optimised lens element shaping to suppress flare and
circular aperture diaphragm for good background bokeh and &removal& of
distracting backgrounds
information passed back to the new E-TTL II flash algorithm of all current
model digital EOS cameras
hood and pouch included in the box
L-series construction
L-series is Canon&s flagship professional lens range, designed and built to meet
the needs of the most demanding professional photographers. The superb optics
of the EF 85mm f/1.2 II USM and other L-series lenses
represent the pinnacle of optical performance, enabling focal length/speed/quality
combinations not readily attainable using traditional optical technologies.
Portrait photography
The combination of an almost circular aperture diaphragm for
attractive bokeh (evenly graduated blurring of out-of-focus areas) and the
extremely narrow depth of field at its widest aperture combine to make this an
ideal portraiture and studio lens. With the lens& aperture at f/1.2,
photographers can create dramatic effects such as keeping a model&s eye sharp
while blurring the eye lash ends.
Low light shooting
The maximum f/1.2 aperture is the widest in Canon&s current
range and provides for shooting in low light conditions without the need for
flash or slow shutter speeds. With improved auto-focus speed from Canon&s
latest Ring-type Ultrasonic Motor (USM), the lens is expected to be popular
with professional photographers shooting indoor sports. The USM holds the lens with precision and accuracy, the instant it
arrives at the correct focus and without overshoot, and features full-time
electronic manual focus override*. Super-fine
control over depth of field afforded by the lens& large aperture allows sports
photographers to deliberately &blur out& crowds, hoardings and other
distracting backgrounds.
Aspheric element
Wide aperture lenses using traditionally
manufactured elements suffer from spherical aberration which causes an overall
softening and optical &smearing& of the image. To ensure high corner-to-corner
sharpness and contrast of in-focus subjects throughout the focus range and at
wide apertures, the
EF 85mm f/1.2 II USM incorporates a large aspherical lens element with precise
variable curvature and a floating group construction.
Super Spectra coatings
In addition to optimised 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 colour balance.
E-TTL II flash integration
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.
In keeping with Canon&s Kyosei
philosophy of living in harmony with the environment, the lens features only
lead-free glass.
