Canon’s proprietary optical technology that realizes

high image quality EF Cinema lenses*

Canon's superb optical material technology

Lens with ultra-long focal length, 4K optical performance, and high carryability

Multilayer coating technology that reduces lens

flare and ghosting

[Fluorite]

Theoretically, a slight chromatic aberration

always occurs in standard optical glass. The

use of fluorite resolves this issue by making

the ideal chromatic aberration correction.

Many of Canon’s zoom lenses demonstrate a

correction effect particularly at the telephoto

side that has a large aberration.

Theoretically, in order to shoot an object dimension in Super 35mm equivalent to that of a 2/3” format camera lens, it is necessary

to have a focal length that is about 2.7 times longer, which significantly affects the size of the lens. To obtain the brightness of a

long focal length lens, a large diameter lens is required, thus making the size of the lens front huge. Because there is a close

relationship among focal length, optical performance, and size of the lens, highly advanced technology is required to achieve the

proper optical balance among them.



Canon has put together industry cutting-edge technologies such as advanced optical simulation technology, as well as the

optimal layout of the glass and mechanical components, wide-diameter aspherical lens technology, and the most suitable

optical glass materials to develop a lens that achieves a high level of total balance.

The newly developed EF Cinema lenses and EF lenses have a coating that is

optimized for digital camera photography. For example, these lenses are provided

with the optimal multilayer coating to prevent the reflection of incident lights on a

lens and to reduce flare and ghosting. The EF Cinema lenses use an anti-reflection

lens coating that further reduces the occurrence of flare and ghosting.

[UD and Hi-UD glasses]

An Ultra-low Dispersion (UD) glass has characteristics similar to fluorite. Since a UD glass has low

dispersion as well as abnormal dispersibility, it can produce an effect similar to fluorite with an

optimal layout of the glasses. A Hi-UD glass has a high refractive index and provides chromatic and

spherical aberration correction effects while also providing the low dispersion and abnormal

dispersibility of a UD glass. A Hi-UD glass is used in such products as zoom lenses and works

effectively to reduce the aberration fluctuations caused by focusing and zooming, in addition to

reducing the chromatic aberration that occurs at the telephoto side.

Aspherical lens technology

A spherical lens refracts more in the peripheral parts than in the center.

For that reason, these lenses are subject to spherical aberration. On the

other hand, an aspherical lens can gather all light that passes through

the center and peripheral parts of the lens at one point. This technology

makes it possible to use an aspherical lens to provide the same

correction effect that would normally need several spherical lenses, thus

reducing the overall number of lenses required. This technology

therefore helps produce sharp images through high optical

performance, as well as being compact and lightweight.

*: Technology applied to the lenses would differ depending on the model.

CN20×50 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.

Lens with ultra-long focal length, 4K optical performance, and high carryability

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.

Not all productions will require

the digital servo drive, with

many preferring traditional

manual cinematography style

shooting – Canon has designed

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 specic 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).
