Features
Outstanding Optical Performance
New design tools, encompassing cutting-edge optical simulation and powerful 3D design
technologies, combined with new optical glass materials and new optical coatings produced
a novel optimization of the cost-performance ratio of this new lens. The KJ20x8.2B IRSD
exhibits a high MTF at picture center that is also well-controlled out to picture extremities. The
design optimization maintains that high MTF with operational adjustments of focal length and
object distance. Longitudinal and lateral chromatic aberrations have been minimized as well as
monochromatic aberrations like coma and astigmatism. Geometric distortion at wide angle settings
is imperceptible.
The new optical materials and multilayer optical coatings have effectively attenuated optical artifacts
such as ghosting, fl are, and veiling glare, that might be stimulated by strong light sources in the
scene (for example, sun in daytime and car headlight at nighttime).
Benefits
- Pre-store and recall zoom positions with the Shuttle Shot function
- Maximum zoom speed of one second from end to end
- Extraordinary Dispersion Glass and multilayer coatings minimize aberrations
- Macro focusing with a minimum object distance of less than one inch
- Quiet, fast servo unit
- Smooth, super-slow zooms
Newly Developed Advanced Drive Unit
Various companies have rolled out cameras with lens aberration correction functions in recent
years. For this reason, the KJ20x8.2B IRSD is fi tted with a camera-communication interface to
support these separate aberration correction functions.*1
*1. Check with the camera manufacturer to see whether the KJ20x8.2B IRSD is compatible with the
camera’s aberration correction functions.
The KJ20x8.2B IRSD’s zoom can travel end to end in 1.0 seconds, an improvement over the
KJ20x8.5B KRS’s speed. The servomotor has a noise-suppressing construction to ensure there is
no corresponding increase in noise. The drive unit features the same ergonomically designed shape
of the KJ20x8.5B KRS and others in the family that users have loved for its handling and grip.
On the newly developed advanced drive unit, the Memo switch, which sets specific zoom
positions for the Shuttle Shot function (see right page), has been changed to a push switch. On
previous drive units, to memorize the zoom position, the operator had to adjust its position by a
volume switch. The memo switch enables more reliable Shuttle Shot setup in the fi eld where more
consistent functioning of the controls is required.
