Another clever solution from Duclos Lenses - this EF Mount Conversion Kit is designed specifically to bring the Sigma Cine Lenses from their original PL mount to a reliable EF mount for use on a wide range of motion picture cameras. Comprised of a sub-mount machined from billet aluminum, anodized black and a stainless steel EF flange for a robust, reliable fit. The Duclos EF Mount Kit is compatible with the complete line of Sigma Cine Primes and Zooms and is fully sanctioned by Sigma, retaining the factory warranty. Applicable on original PL mount (non-i/data) primes and zooms only. View our Quick Look Video here.
