In 1997, Sony® Corporationasked Panavision® to helpdevelop a camera systemwhich would be used bycinematographers to cre-ate motion picture qualityimages f rom a new 24 frame CCD camera.Panavision’s customershad also been asking for adigital camera system tailored to their needs asfilmmakers.
Panavision® realized that acomplete imaging systema p p r o a c h w o u l d b e
imperative for a new digi-tal camera with no motionpicture precedents. Thebasic HDW-F900 wasdesigned to be an ENGstyle hand held cameraintended to support lightweight ENG style lenses.
Panavision® has ruggedi-zed the camera and devel-oped a lens mount that willsupport our new series ofPrimo Digital® lenses. Thecamera will also interfacewith all appropriate exist-ing Panavision accessories.
The 2/3" CCD imager isactually only 11mm indiagonal (as compared tothe 27.5 mm diagonal of a35mm motion picture filmframe). Therefore, for anygiven screen size, the 2/3"CCD will require 2.5 timesmore horizontal magnifica-tion than a 35mm filmframe. This required thatour new Primo Digital®
lens series be designed toh a v e 2 . 5 t ime s t h e
performance of our bestcine lenses (fortunatelyfor a smaller image size).All of the new PrimoDigital® lenses will providetheir optimum perform-ance at their maximumaperture, including ourtwo new f1.5 11:1 andwide angle 4:1 PrimoDigital® zoom lenses,which are more than 1stop faster than any otherzoom lens designed for the2/3" CCD format.
On the left side of thisgraphic is a 16x9 format,35mm film camera aper-ture. On the right is theimage area of a 2/3" CCDdrawn to the same scale.In order to have the same
performance as a Primocine lens, Primo Digital®
lenses must achieve 80%contrast at 50 line pairsper millimeter on the 2/3"CCD (2.5 times better fre-quency response).

THE IM PORTANCE OF OPTICS
Historically, 525 and 625 linevideo systems were con-strained in their perform-ance by almost everythingbut optics. However, withSony's introduction of thefirst progressive output2/3", 2 million pixel (percolor) CCD camera it wasimmediately apparent thatoptics were going to be crit-ical to maximizing the performance of a DigitalCinematography System.
Panavision® has thereforeintroduced a new series oflenses, designed specificallyfor prism beam splitters andthe small target size of the2/3" CCD. The PrimoDigital® lens series isdesigned to provide the max-imum image performancefor this format while retain-ing all of the other lens char-acteristics Panavision’s®
customers have come toexpect from Primo® lenses for film.

In addition to requiring 2.5 times the frequency response of itscine counterpart, the smaller target also has 2.5 times greaterdepth of field for the same angle of view and f-stop as theequivalent cine lens (f4 on 1.85:1 35mm film format is f1.6 inthe 2/3" CCD format). In order to provide creative control overdepth of field, the Primo Digital® lenses have been designed tooperate two stops faster than the equivalent cine lenses.
Panavision has designed the Primo Digital® series of lenses inorder to address the issues of resolution and depth of field thatthe 2/3" CCD format creates for the cinematographer. Theselenses will provide the same high contrast with low veiling glareas first established by the Primo® cine lenses. The first twolenses, available now, are functionally equivalent to the Primo11:1 and 4:1 wide angle zooms.
Panavision’s next offering, will be two lightweight zooms and aseries of primes beginning with a low distortion 5mm wideangle (equivalent to a 12.5mm in 1.85:1 Academy format).These lenses will provide the same high performance at fastapertures. Primo Digital® primes will be T1.6 or better, andweigh less than 6 pounds (or 2.7 Kilos).
As with film, Panavision is committed to continually developingour digital camera system in collaboration with our clients, toensure that their needs are met.

The “film” versus the “video” look is an extremely controver-sial issue, and is an aesthetic decision based on many factorsthat include colorimetry, gamma, frame rate, image enhance-ment, granularity, etc. The Primo Digital® lenses have aunique internal design which enables interference type spec-tral modification filters to be incorporated within the lenses.When coupled with other optical pre-filters within the cam-era beam splitter optics, the “Panavised” camera can achievea wider color gamut than standard CCD video cameras.
