This highly sophisticated Full Frame Xpander, with PL mounts on front and rear, is optimized to work with classic Zoom Lenses that were originally designed to cover the 35mm film Academy Aperture. Tested to fit the Angenieux 24-290 Optimo, Angenieux 17-80 Optimo, Angenieux 17-102, Cooke 18-100, Cooke 25-250. It will most likely fit other zoom lenses from that era. Ask us, and we will try it.
It easily converts these lenses to cover Full Frame in cameras such as the new Alexa Mini LF, the Sony Venice 1 & 2, and the Red V-Raptor.
