RECOMMENDED KIT CONFIGURATION

THE DIFFERENCE BETWEEN IRSE S AND IASE S TYPE LENSES

IRSE S lenses are the standard type of portable lens with a Servo Zoom Digital Drive Unit. For Servo Focus 
operation, IRSE S lenses require both a Servo Focus Module and a Servo Focus Demand. The IASE S lenses are a 
special type of portable lens equipped with a Digital Drive Unit offering both Servo Zoom and Focus. For servo 
focus operation, IASE S lenses only require a Servo Focus Demand. The IASE S lenses can be used in both the 
studio and the field.

ZOOM TRACK

“Zoom Track” allows the camera operator to adjust 
the electronic focal length to their desired range by 
memorizing zoom positions at both the tele and the 
wide side of the zoom. 

ERGONOMIC DRIVE UNIT

The HDxs, eIFxs, and HDgc (IRSE/IASE model) Ergonomic Drive Unit is tilted at an 
ideal angle of 12.5° to realize good balance and comfort. An information display has 
been added which now allows the user to customize the enhanced digital functions 
easily, precisely, and fully. The enhanced digital functions are easily accessed and set 
via the Digital Function Selector, an X-Y axis switch located next to the display.

IMPROVED MAXIMUM ZOOM  
AND FOCUS SERVO SPEED

Zoom: 0.5 sec., Focus: 1.5 sec.

DIGITAL ZOOM AND FOCUS 
DEMANDS

Canon offers a series of servo controllers for Digital Drive lenses. 
The ZSD-300D (zoom demand), FPD-400D (focus demand), and  
FPM-420D (focus servo module) support the Digital Driver’s 
functions. These demands are connected to the “Digital Drive” via a 
20 pin one-touch type connector, which makes the connecting and 
disconnecting easy and quick. Also with the FPD-400D,  
focus servo operational curve can be selected unlike the 
conventional focus demand. The digital series of demands and  
the conventional demands have complete compatibility with each 
other, except for the digital functions. (A conversion cable may be 
required. Please refer to page 39.)

VIRTUAL STUDIO COMPATIBILITY

Canon has a series of  HDxs, eIFxs, and HDgc (IRSE/IASE model) 
lenses which are equipped with an enhanced  
digital drive unit. Conventional potentiometers are analog 
positional sensors capable of only 8-10 bit equivalent resolution. 
Due to this, virtual studio systems with portable lenses called for 
an optional Encoder Unit to be put on the Zoom and Focus ring of 
the lens. With the introduction of 16 bit resolution  
Rotary Encoder Devices built into the enhanced digital drive 
unit, the lens can be simply integrated into a virtual digital studio 

system without any additions. The encoders also enable superior precise control. The zoom servo provides a dynamic range of 0.5 
sec. quick zooms to over a 5 min. super slow zoom. Repeatability in Focus and Iris control are also precise. Canon’s technology has 
made the Encoder Device surprisingly small to be installed in the existing drive unit without changes in size or weight.
