The Metabones Speed Booster Ultra 0.71x Adapter allows Minolta MD, MC, and SR lenses to be mounted on FUJIFILM X-mount cameras, reducing crop factor while increasing the effective aperture by 1 stop. Its 5-element/4-group optical design ensures sharpness and color fidelity, and a detachable Arca-Swiss compatible tripod foot provides stable support for heavier lenses. Fully manual operation, no electronic communication.

Boost the performance of your classic Minolta MD-mount lenses with the Metabones Speed Booster Ultra 0.71x Adapter for FUJIFILM X-mount cameras. Designed to condense the light projected from full-frame lenses onto the APS-C X-mount sensor, this adapter reduces the crop factor while providing a 1-stop increase in maximum aperture, giving your lenses improved low-light performance and shallower depth of field.

Constructed from durable yet lightweight aluminum alloy with brass mounting rings to prevent wear, the adapter incorporates a precision 5-element/4-group optical system engineered for clarity, contrast, and accurate color reproduction. The Speed Booster features a secure locking mechanism and push-button lens release for safe and convenient operation. A detachable tripod foot with 3/8" threads is included and compatible with Arca-Swiss tripod heads, making it ideal for professional shooting setups.

Please note: This adapter supports full manual operation only; electronic communication, autofocus, and in-camera aperture control are not available.
