IAS H
With the advance of digital cinematography, most new digital cine cameras have made use of the entrenched large global inventory
of 35mm motion picture film lenses. Digital cinematography has squarely encompassed the emerging 4K movement – in both the
television-centric UHD and the cinema-centric 4K digital motion imaging production formats.
In the broadcast industry, large-format cameras and lenses for digital cinema are now being adopted for applications such as dramas,
documentary programs, and promotional videos because of their superb imaging characteristics.
Documentary, sports coverage and natural history programs seek extended focal ranges. Such focal ranges in the Super 35mm image
format size with full 4K optical performance, pose significant challenges to size and weight of the lens.
In recognition of this pressing production need, the CN20×50 IAS H ultra-telephoto zoom lens in Super 35mm format has been
developed, significantly extending the imaging capabilities of 4K large-format cameras.
The CN20x50 IAS H is a zoom lens for the Super 35mm format,
having the superiority of the longest focal length(*) of 1500mm
(with a 1.5× extender) and the highest zoom ratio(*) of 20× in
the world of the Super 35mm format that offer a whole new
image expression.
Built-in 1.5× "4K" extender is another first in the large format
optical arena, which maintains excellent 4K image quality.
The lens weighs only 6.6 kg and has an overall length of only
405.2mm (**) a combination that will readily support carryable
documentary, natural history and sports shooting.
Powerful 4K images created by unprecedented 1500mm focal length
4K Optical Performance
The 4K optical performance is carefully managed across the entire image plane to ensure superb subjective sharpness especially
on the wider angle settings. Sophisticated computer simulation in the design phase produced an excellent final optimization that
maintains the 4K optical performance over the entire focal range even when the built-in extender is in use and over an object
distance ranging from the minimum object distance to infinity.
New glass materials assisted in the goal of achieving the necessary tight control of optical aberrations.
The most contemporary multilayer optical coatings ensure very high contrast by their superb control of black reproduction
augmented by optical and mechanical design innovations that substantially reduced flare and any internal reflections.
Similar attention to minimization of ghost images and other highlight-related color bleeding extend the operational contrast range
of the lens.

Servo Cine Lens
The CN20×50 IAS H has a newly designed digital servo system that employs the
miniature 16-bit optical encoders that endow the control of zoom, iris, and
focus with the same legendary precision for which Canon is world-famous in
the 2/3” ENG/EFP domain. This new digital drive system is compact and
lightweight while providing impressive power to actuate the full 20:1 zoom
range in 1.5 seconds – ensuring image capture in critical moments.
Wide-ranging zoom speeds up to a maximum of 180 seconds support special
creative shooting. The encoders do not require any initialization operation and
accordingly the system starts immediately upon switch-on.

A 12-pin connection cable from the drive unit carries the standard serial
communication for broadcast lenses – ensuring that the CN20×50 IAS can be
used with all professional Super35mm digital cine cameras. The camera
supplies power to the drive unit via this connection and remote iris operation is
supported.

Imaging Excellence with Optimized Operational Performance
The lens is equipped with multiple blades
that make the aperture diaphragm
rounder and achieves a soft and natural
blur effect. It has also adopted an odd
number of blades so that the beams of
received light spreads without affecting
facing diffraction light each other and
creates a soft and elegant beam of light
when optimal focus is achieved.

the system so that the servo unit
can be removed. In this mode the
manual focus control has a total rotation angle of 180 degrees. If
the drive unit is removed for a specific production and then
re-mounted – this can be done in any rotation position and there is
no need to adjust gear positions (zoom, iris, and focus).
