The T Speed Booster XL 0.64x Adapter for Full-Frame Canon EF-Mount Lens to Select Micro Four Thirds-Mount Cameras from Metabones allows a full-frame Canon EF-mount lens to be mounted onto a Micro Four Thirds-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a 1.3-stop increase for the camera over the lens's aperture range.

It allows me to expand the usage of my Canon wide angle zoom lenses paired with my M43 GX8 camera.
Such as 11-24mm f4L, 16-35mm f2.8L II, thanks for the equivalent magnification factor 1.28 (2*0.64) with this adapter.
And it significantly increases my lens aperture by 1 2/3 faster.
My 11-24mm f4 becomes 14-31mm/f2.8 and 16-35mm becomes 20-45mm/f1.8 equivalent to 35mm full frame lens!!
The only cons is when I paired my Canon 11-24mm F4 with M43 GX8, it is hard to get auto focused at 11mm.
Other than that, I am very satisfactory with my purchase.
But it does not work with my Olympus E-M1 Mark II !
Also the tripod mount screws are on there SO TIGHT that I stripped one of the screws just trying to get it off. Now I have to figure out how to get it off.
I have just one very minor thing to point out. It is just a little loose on my GH4. I am not sure why, but I would think a product like this should fit snug, with no play at all, like the lenses.
