This is a rare, high-speed vintage optic: the J.H. Dallmeyer Speed Anastigmat 1 inch f/1.5 Manufactured in London, Dallmeyer lenses are highly collectible, and this model is exceptional for its incredibly fast f/15 maximum aperture for the 16mm film format.

The 1-inch focal length (approximately 25mm) is considered the standard or normal lens for 16mm cine cameras. Its large aperture allows filmmakers to shoot in very low light and achieve beautiful, shallow depth-of-field effects, creating a unique cinematic look highly desired today.

The lens features the classic black lacquer barrel with bright knurled silver focus and aperture rings. It is built with the standard C-Mount screw thread, making it compatible with vintage 16mm cameras like Bolex and Beaulieu, and easily adapted to modern mirrorless digital cameras for creative use.
