Questar SZ90 is a Multi-Focal Length Lens (MFL) that is fully
motorized and microprocessor controlled. It is a very portable
small aperture lens providing five discrete focal lengths and
five neutral density or spectral filter selections. The lens is
best suited for video use and is shipped ready to connect directly
to any standard C-mount type CCD camera. Visual and 35mm-photography
use is also possible under certain restrictions. With some modification,
various special applications in tracking and surveillance can
be addressed. The Questar SZ90 is composed of the new MKIII barrel
assembly, MFL multi port housing, microprocessor controlled CPU
board, hand held controller and a universal A/C to D/C power supply.
This unit requires 12 VDC to operate.
