Cooke Optics launches S8/i Full Frame: a series of full-frame all-spherical design lenses

Cooke Optics has recently launched a series of seven lenses for full frame production with an all-spherical design and T1.4 throughout named S8/i Full Frame (FF). The focal lengths included are 25mm, 32mm, 40mm, 50mm, 75mm, 100mm, and 135mm. Nine more lenses will join by the end of 2022, as the company has informed.

The S8/I origin is motivated by feedback from cinematographers wanting to create more realistic and film-like images with spherical lenses for digital motion capture. To achieve this, Cooke has focussed on optimising the contrast performance for the S8/i. Crucially, human perception of resolution is tied to contrast, so an observer will perceive a sharp image due to the synergy and balance of both.

Under the body, S8/i is an all-spherical design which produces a near telecentric output of the light rays which is efficient for sensors. It is characterised by smooth, spherical bokeh and minimal colour fringing.

Tim Pugh, CEO, Cooke Optics, said, “We are very proud to reveal the new S8/i FF series, built as always with cinematographers in mind. The lenses have been designed and produced in a smart way using an all-spherical design which provides an organic, filmic aesthetic to accompany the latest digital film cameras.”
