Cooke 45-405 T4.5 Anamorphic/i Zoom

FDTimes’ sketch of possible look of Cooke 45-405 2x Anamorphic/i.

At a famous Cooke NAB Dinner in 2015, after swearing the entire conclave to secrecy, Les Zellan had a surprise. After giving details about the new 35-140 Anamorphic/i lens that would be the first of two zooms in the Cooke Front Anamorphic series, he said, “A second zoom—a long, front anamorphic—should be revealed in 2016.”

True to form, exactly one year later, the next Cooke Front Anamorphic/i zoom lens will be shown at NAB. It will be a 45-405 T4.5. Since Cooke appears to be more punctual lately, the 45-405 Anamorphic/i zoom might be ready to review at our next NAB gathering in 2017.

Les described the 45-405 Anamorphic/i zoom: “The long zoom will match all the models in our front anamorphic lens set. It is a true front anamorphic zoom. The pleasing oval bokehs that are currently consistent throughout our entire range of Cooke anamorphic zooms and primes will continue to be a feature of this new zoom lens.”

45-405 Prelimary Specs

These preliminary specifications are subject to change.

9x zoom front anamorphic like all
T4.5-22
2x anamorphic squeeze
MOD from image plane: 5’10”
Close focus measured from front of lens: 3’11”
6.1:1 magnification at close focus
Cooke Look, color and contrast will match rest of Cooke Anamorphic series and all Cooke lenses
Weight: 25-26 lb / 11.3-11.7 kg
Length 21.2” / 537 mm
Internal front anamorphic group of optical elements is 5.7” long. Since the cylinders are in front, that is why this lens is longer.
Front diameter: 136 mm — same as 35-140 zoom
Elliptical bokeh throughout the entire zoom range
Bokeh match all other Cooke anamorphic primes and zoom
Depth of Field (DOF) is the same as the Cooke anamorphic primes. Since these are front anamorphics, the Vertical DOF is approximately half the horizontal values. Horizontal is wider, hence more depth.
In the Depth of Field Tables, the listings are for Vertical DOF, which are more critical.
-20 to +50 C / -4 to +122 F operational temperature range without change in focus. Because of long length, special materials were used in critical areas to counteract the effects of expansion and contraction from heat and cold.
