Cooke Front Anamorphic/i SF Prime Lens - 75mm T2.3

All of the anamorphic lens characteristics demanded by filmmakers today with the Cooke Look® and oval bokeh. That’s the Cooke Anamorphic /i Look. Images beautifully rendered for film and especially suited for use with digital cameras. The Anamorphic /i lens correct aberrations exceptionally well over the entire image area – astigmatism, lateral and longitudinal colour – that will render shape, form and soul to your images.

While the "look" is crucial, precision engineering and seamless integration with other equipment is equally important. The Anamorphic /i, prime lenses in ten focal lengths are colour matched to our S4/i, 5/i and miniS4/i lenses.

Ideal for close-ups and product shots, the Cooke 65 mm Macro Anamorphic /i 2X Prime lens has magnification ratio 4.1:1 with close focus of 5.5" from front of lens.
 
Now, you have even more latitude. We went one step further with our new Anamorphic/i SF lenses that are specially manufactured with a coating that allows for even more creative options. The “SF” stands for Special Flair because they allow you to kick the flares, bokeh and other aberrations into new visual territory. Complementary to the Anamorphic/i lens series, they are offered in 25mm, 32mm, 40mm, 50mm, 75mm, 100mm, 135mm, 180mm, and 300mm focal lengths. 
The Anamorphic /i lenses offer superb optical and mechanical performance. Distortion, veiling glare, flares, and all aberrations are controlled at all apertures over the whole field of view. Like our S4/i, 5/i and miniS4/i prime lenses, the cam focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability. The Anamorphic /i lenses are designed and made by us to our traditional high standards in Leicester, England.  Feature Highlights

The Cooke Look® and colour matched with all other Cooke prime lenses.

Especially well balanced for astigmatism and corrected for lateral and longitudinal aberrations over the entire image area

Linear iris

Equipped with the next generation of /i Squared Technology* for lens metadata capture

Award-winning cam-style focus mechanism allows for smooth focus adjustments  
Our Cooke Anamorphic/i Prime lenses are supplied with /i Technology, and are designed for all PL mounted professional motion picture film and electronic cameras. The /i Technology provides cinematographers and camera operators with vital information on lens setting, focusing distance, aperture and depth-of-field, hyperfocal distance, serial number, owner data, lens type and focal length in both metric and footage measurements. For zoom lenses, the zoom position is displayed.

Optical Design

The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.

Electronics

Accessible via cable connector near the lens mount and contacts in mount that sync with /i compatible cameras and accessories.

Colour Balance

All Cooke Anamorphic/i prime lenses are colour balanced to a specification within parameters approved by Kodak and are colour-matched and compatible with Cooke 5/i, Cooke S4/i, miniS4/i, and CXX 15-40 mm T2 S4/i Zoom lenses.

Aperture

All Cooke Anamorphic/i primes have a true T2.3 aperture and cover Super 35mm format except the 65mm MACRO which has a T2.6 aperture.

Index Marks

Every index mark is labeled. More detailed markings allow for more detailed focus control.

Focus Movement

Our Academy Award® winning cam-style focus movement coupled with the added benefit of a large lens barrel diameter, has allowed for an increased number of focus markings, particularly at close focus. Spherical aberration has been controlled throughout the range of focal lengths to eliminate compensation of changes in back focus with aperture. A four-point contact bearing provides a smooth positive backlash-free movement.

Focus Scaling

Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions. Plus the the Entrance Pupil position is engraved on the lens.

Camera Mounts

Cooke Hardened PL Mount with /i Technology contacts.

Compatibility

All Cooke Anamorphic/i lenses have a common, fixed front diameter of 110mm, except for the 25, 65 MACRO and 300mm focal lengths and the Anamorphic/i zoom lenses, which are 136mm. All have an iris drive gear of 134T x 0.8.

External Finish

A scratch resistant PTFE hard anodised finish is provided on all Cooke lenses, providing a durable, hard-wearing surface to meet the most demanding environmental conditions.

Iris

An eleven-leaf linear module iris assembly is fitted into Cooke Anamorphic/i primes with an aperture range of T2.3 to T22; T2.6 to T22 on the 65mm MACRO, T2.8 to T22 on the 180mm, and T3.5 to T22 on the 300mm.

Weight/Size Ratio

The lenses are designed for all shooting applications, including handheld and Steadicam, providing comfortable balance ratio with the latest compact cameras.

Reliability and Service

Cooke Anamorphic/i prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
