This adaptor works great with most of my Canon Lenses, but the most important one (24-70) it did not work on and kept generating an error on the camera that the Lens wasnt connected properly, so it became fairly useless and I ended up buying a Micro Four Thirds lens. Tried to get assistance from Metabones, but they wanted me to send it back to them (in Asia) at my expense which was over $200 from my location. At this point its permanently attached to my 70-200 Zoom lens and works great, but Im very frustrated that it didnt work with the intended lens.

Originally purchased this to use with my Olympus OMD E-M1 and my Pen-F. Worked good with the OMD, and great with the Pen. However, recently I upgraded the OMD to the Mark II. Unfortunately, this adapter will not work with the OMD E-M1 Mark II (at least not at this time). According to Metabones "the optical element of our SpeedBoosters and the sensor of this camera is too close". So, be aware that if you plan to use this with the OMD E-M1 Mark II, it will not work.

It is nice to buy a product these days that lives up to expectations. This one exceeded mine. I was a Canon 7D shooter and had a good amount of glass, including, L glass. Switching to the OMD em1 mk2 system has been awesome but I wondered whether I could make use of my Canon lenses. So the choice was whether to buy another Olympus lens, in this case, the awesome 75mm or get the Metabones speedbooster. All I can say is WOW. My new favorite lens is my Canon 85mm mounted on my Olympus. Nothing short of amazing. All of my Canon EF lenses focus instantly with no delay. The added speed on the lens creates amazing bokeh. My Canon 70-200 L lens is now an awesome equivalent of a roughly 100-285 mm that is really useful because of the OMDs IBIS. In short I am very pleased and would make the purchase again.

I love that I can use all my Canon glass on my Lumix GX7. You need to accept some limits such as single focus only, no flexible or continuous focus but the cost saving of buying all new 2.8 glass is well worth it.

Returned, failed to focus on a new panasonic micro 4/3 camera (that works) and any of many Canon lenses I own. Updating the firmware did not help.
