Remote extender  
Tokina employed the extender system  
which has been used for TV broadcast  
zoom lenses in contrast to conventional  
extenders attached to the rear end of a  
lens, this extender has been incorpora  
ted into its optical system itself from the  
designing stage to ensure that an opti  
mal extender most appropriate for the  
lens should be developed. Moreover,  
use of a motorized system for moving of  
the extender has allowed it to be remote  
ly controlled.  
Expensive super low dispersion glass  
which has been used for TV Broadcast  
lenses is used in the frontal part of the  
lens to eliminate in an ideal manner the  
secondary aberration occurring at the  
telephoto side.  
The system allows the cam grooves to  
be cut by an easier gradient. This will  
permit at the same time the strength of  
the cam barrel to be increased relative to  
that of the conventional system. An  
increase of precision in the direction of  
the optical axis has made it possible  
for an ideal optical performance to be  
achieved at a value almost identical with  
that of the design. With a decrease of  
the load to the zooming and focusing  
motors, the overall durability has signifi  
cantly enhanced.

Triplet compensator  
Tokina has solved the problem of a  
deterioration of the center performance  
at around halfway of the zooming range  
with this compensator. The deterioration  
is a characteristic commonly observed in  
telescopic lenses with a high magnifying  
power. A result of the Tokina's advanced  
optical technologies, the compensator  
prevents the deterioration from occurring  
and achieves a high resolution over the  
entire zooming range.  
High resolution suitable for  
3CCD cameras  
The progress in the use of 3CCD cam  
eras is remarkable in recent years. Pro  
vided with a high resolving power, the  
lens will allow you to fully utilize the cam  
era's performance to obtain images in  
bright colors with high resolution.
