Canon Embraces
3D High Definition
Anticipating the boom in popularity of 3D, Canon has been actively
engaged with HD camera manufacturers, 3D rig specialists, and
enterprising content creators presently exploring 3D program
origination in moviemaking, as well as television coverage of
sports, concerts, and special events. Recognizing the importance
of 3D program origination, Canon gave priority to adoption of most
of the standard HD lens series for 3D production systems.
3D Lens Solutions
A pioneer in the development of precision Digital Drive Units for its
portable lenses, Canon's 3D control systems for lens-camera pairs
capitalize on the ability to synchronize the servo control systems
within the pair, and to then use the associated menu system to
enter correction data that ensures precision tracking for their
respective zoom, iris, and focus operations. A simple 20pin -
20pin 3D bridge cable interconnects the stereoscopic lens pair,
and special 3D software loaded into the two Digital drive Units
performs the requisite synchronization. A single Zoom controller
connected to one lens will then simultaneously control the zoom
action of both lenses. Similarly, a single Focus controller
connected to the other lens will simultaneously control the focus
operation of both lenses. The 3D software can be installed into
most standard Canon lenses at Canon service centers.
3D Lens Controllers
A special attraction of Canon's synchronous lens control system is
the use of standard rather than specialized controllers. When the
3D software is installed in the lens drive units, all standard servo
controllers for zoom and focus will be fully compatible with
Canon's stereoscopic lens-pair, thus facilitating a significant cost-
saving when deploying standard lenses for 3D acquisition
systems.
System Configuration
*1 BDC-10 conversion cable is necessary to connect between ZDJ-D02 or FDJ-D02 (18pin) and Digital Drive Lens (20pin).
*2 BDC-20 conversion cable is necessary to connect between ZDJ-P01 or FDJ-P01 (12pin) and Digital Drive Lens (20pin).
EF Cinema Lenses
A Revolution in Digital Cinematography
Canon has produced two high performance
Cinema zoom lenses as
integral components of the
Cinema EOS system.
Between the two lenses,
they cover the focal ranges
most commonly encountered
in moviemaking and high-end
television production. The wide angle
CN-E14.5 – 60mm T2.6 L SP is a new
generation cine zoom lens whose design
is based upon a new optical platform that sought beyond-4K
performance. In every sense, the lens can be used as a variable prime
lens – offering superb contrast and sharpness across the Super 35mm
image plane, constant optical speed over the entire focal range, and
virtually zero focus breathing. Chromatic aberrations and geometric
distortion are imperceptible.
The telephoto CN-E 30 – 300mm T2.95-3.7 L SP offers an extended
range of focal lengths that will cover most requirements in television
production as well as special requirements in moviemaking. This lens
was also designed to exceed 4K optical specifications.
These precision matched lenses ensure the highest imaging
performance in contemporary digital HD cine cameras while definitively
future-proofing the transition to digital 4K motion imaging. Computer
simulation based upon the ISO Color Contribution Index (CCI) was
employed to achieve a very tight match in color reproduction between
these lenses. Canon’s innovative optomechanical design counteracts
temperature-induced marking discrepancies. An 11-blade aperture
diaphragm produces a highly aesthetic bokeh.
Uncompromising Design for Working Professionals
Each lens has markings on angled
surfaces on both sides of the barrel,
making it easy to read settings from
behind or either side of the camera,
and they can be switched from
standard to metric depending on
production need. Control rings
maintain the proper amount of
resistance with consistent operating
torque. A covered flange-back
adjustment mechanism is included as
well. They are also among the lightest
and smallest lenses in their class. Both
lenses share the same gear position, diameter, rotation angle, plus the
same front lens diameter and compatibility with third-party accessories,
allowing for crews to easily change between the two lenses without
adjustments to the rig setup.
Uniform gear positions,
diameters, rotation angles
and front lens diameters.
