Metabones T Speed Booster XL 0.64x Adapter for Full-Frame Canon EF-Mount Lens to Select Micro Four Thirds-Mount Cameras. I am the original owner. I purchased this brand new in 2015, but have barely used it. It's in excellent condition. Comes in box with original accessories.
The Metabones T Speed Booster XL 0.64x Adapter is a nifty little device that bridges the gap between full-frame Canon EF lenses and Micro Four Thirds (MFT) cameras. If you're a photographer who loves mixing and matching gear, this adapter opens up exciting possibilities. Let's break down the details:
Purpose and Compatibility:
- The Speed Booster XL 0.64x is designed to mount full-frame Canon EF lenses onto Micro Four Thirds camera bodies.
- It's compatible with select MFT cameras, including models from Panasonic (such as the GH5 series), Olympus, and Blackmagic (specifically the Pocket Cinema Camera and Micro Cinema Camera).
Optical Magic:
- The adapter's optical design is where the magic happens. It condenses the light from a full-frame lens and projects it onto the smaller MFT sensor.
- Result: You get a wider field of view (approximately 0.64x wider) than if you were using the same lens directly on an MFT camera.
Aperture Boost:
- The Speed Booster XL increases the maximum aperture of your lens by approximately 1⅓ stops. So that f/2.8 lens suddenly becomes more like an f/1.8 in terms of light-gathering capability.
- This extra light can be a game-changer for low-light shooting or achieving that creamy bokeh.
Electronic Communication:
- Autofocus: The adapter supports electronic autofocus, which is great news for those who rely on AF.
- Iris Control: The aperture can be controlled directly from the camera body, just like with native MFT lenses.
EXIF Data and Distance Information:
- The adapter allows you to capture EXIF metadata, including focal length, aperture, and zoom range.
- Some lenses even display distance and zoom information on compatible camcorders.
Stabilization and IS Support:
- If your lens has image stabilization (IS), fear not! The Speed Booster XL supports it.
- It also plays nicely with in-body image stabilization (IBIS) on certain MFT cameras.
Build Quality and Extras:
- The adapter features a robust build with six optical elements arranged in four groups.
- A locking mechanism secures the lens in place, and a rubber gasket keeps dust and moisture out.
- The detachable tripod foot is compatible with Arca Swiss, Markins, and Photo Clam ball heads.
Limitations:
- Not all lenses play well with the adapter. Some third-party DX lenses may remain incompatible even after modification.
- On the Panasonic GH5, the Speed Booster XL works only with full-frame lenses.
- Autofocus accuracy with certain Tamron lenses might not be perfect.
- Canon Cinema Compact-Servo lenses are not supported for still photography.
- Iris changes occur in 1/8 stop steps, which could be noticeable in video recordings.
In summary, the Metabones T Speed Booster XL 0.64x Adapter is like a bridge between two worlds—a way to marry your beloved Canon glass with the compact power of Micro Four Thirds cameras. Whether you're shooting stills or video, this adapter opens up creative opportunities and lets you explore new horizons.
