Canon EF to Micro Four Thirds T Speed Booster XL 0.64x

The Metabones T Speed Booster XL 0.64x Adapter enables full-frame Canon EF-mount lenses to be used on Micro Four Thirds-mount cameras while maximizing the apparent angle of view and providing a 1.3-stop increase in effective aperture. The adapter's six optical elements in four groups are designed to preserve optical clarity and color fidelity while condensing light from the full-frame lens onto the smaller Micro Four Thirds sensor. Electronic communication between the camera and lens is maintained, allowing autofocus, image stabilization, on-camera aperture control, and EXIF metadata recording to function as intended.

Constructed from aluminum alloy with brass mounting rings, the adapter features a detachable Arca-Swiss compatible tripod foot with 3/8" threads and weighs only 6 ounces. The integrated locking mechanism with push-button release securely attaches the lens, while an internal jog dial on compatible Panasonic cameras provides incremental aperture adjustment. This adapter is compatible with select Panasonic Lumix models, Olympus PEN E-PL7, and Blackmagic Cinema cameras with Micro Four Thirds mounts.
