Cooke Speed Panchro 121mm f/2.0
(INSERT SINGLE HERO IMAGE HERE - other images below in media section)
Summary
By 1930 Lee had updated his Opic designs and began to create the ‘Speed Panchro’ lens line specifically for cinematographic applications (U.S. patent 1955591A). An advertisement for these lenses ran in the November 1930 edition of The International Photographer and December 1930 edition of American Cinematographer. The lens designs reflected all Lee had learned in making the Opic and Ultra Speed lenses. This non-coated range was made up of 13 lenses ranging from 24mm to 121mm with an aperture of f/2.0 across the series. It’s worth noting however that without any coatings the effective T-stop would not have reached close to T2.
