Product details

Overview

The Metabones Canon EF to Micro Four Thirds T CINE Speed Booster XL 0.64x maximizes lens performance by reducing crop factor, increasing aperture by 1 stop, and delivering a wider field of view. Featuring advanced 6-element optics and full electronic integration, it supports autofocus, image stabilization, and smooth iris control for professional cinema and photography use.

Performance

This high-performance optical and electronic adapter is designed to unlock the full potential of Canon EF lenses on Micro Four Thirds cameras. With its advanced 0.64x optical reduction, it significantly reduces crop factor while increasing the effective aperture by 1 stop, enabling superior low-light performance and enhanced depth of field control.

Design

Engineered with a patented 6-element/4-group optical design by Caldwell Photographic in the USA, this Speed Booster delivers improved sharpness, higher MTF, and reduced distortion while expanding the field of view. It supports 4K video modes with DX lenses (except GH5), making it ideal for professional cinematography.

Features

Fully electronic, the adapter supports autofocus, electronic aperture control, image stabilization (IS), and EXIF data transmission. It is compatible with in-body image stabilization (IBIS) systems found in Panasonic and Olympus cameras. Smooth iris functionality is available with newer Canon, Tamron, and Sigma lenses, while Cinema EOS lenses are supported when powered via an optional external 5V micro-USB supply.

Construction

The adapter features a positive-lock EF mount for secure lens attachment, a rubber gasket for dust and moisture protection, and a flocked interior to minimize internal reflections. A detachable Arca-type tripod foot provides stable mounting for heavier setups.
