Overview
The Cooke Anamorphic/i Full Frame (also marketed as Anamorphic/i Full Frame Plus) is a series of anamorphic prime cine lenses from British manufacturer Cooke Optics. Introduced in 2018, it is designed for large-format and full-frame cameras, with an image circle covering a 24 x 36 mm sensor (approximately 43 mm diagonal).
A characteristic feature is the 1.8x squeeze – a compromise between the classic anamorphic look (compression, oval bokeh, horizontal flares) and efficient pixel utilization of the full-frame sensor. With 1.8x squeeze, aspect ratios up to 2.40:1 (approx. 90% of pixels) or up to around 2.70:1 with full sensor usage can be achieved. The lenses deliver the typical “Cooke Look” with soft skin tones and gentle bokeh.

Variants and /i Technology
The series is available in two versions:
- Standard: the regular, well-corrected anamorphic lenses.
- SF (Special Flare): with proprietary coating for emphasized flares, oval bokeh, and other intentional aberrations.
All lenses support Cooke /i Technology, which records lens metadata frame-by-frame – including focus position, aperture, depth of field calculations, hyperfocal distance, and serial number. This simplifies VFX and post-production workflows.
On-Set Usage
The series is used in feature film, television series, and high-end commercial productions aiming for an anamorphic look on full-frame sensors (e.g., ARRI ALEXA LF/Mini LF, Sony VENICE, RED Monstro). As the front diameters vary between focal lengths (110 mm or 136 mm), appropriate adapter rings must be used for matte box and filter setups. The /i metadata is read via compatible cameras and recording systems.
