I rented this because I just bought the new NEX 7 and typically I am a canon shooter, so I have quite a few top end canon lenses. The first lens I tried was my 70-300. Every shot had corner vignetting. Pretty good heavy vignetting at that. Next I tried my 70-200 2.8 lens. Same thing. Heavy corner vignetting on all my shots. I wrote to the company,Metabones, and told them what I was experiencing and sent them a couple of photos. They came back and said it was the nature of my lenses, not their product. Using telephoto lenses would cause that. Well I wrote back and said ok, perhaps, but I also used my 100 mm macro prime lens and got the same result. They said they would have to check with their engineer and get back to me. This time they didn't get back to me. So I am glad I rented it and didn't buy it outright. Two good things tho. I could certainly crop the corners out of each photo and got a nice sharp shot thru the lens. So for that respect it works well. Renting this also kind of gave me a wake up call. I bought the Sony NEX7 so I wouldn't have to carry around llarge bulky equipment anymore. Putting those big lenses on the smaller camera kind of defeats that purpose.

The Metabones Canon EF lens to Sony NEX Speed Booster essentially widens the image captured on Sony’s crop sensor and allows for more light to enter the camera. The glass inside the adapter focuses the image coming from the lens, making a smaller circle image and filling the crop sensor similarly to how the lens would normally fill a full frame sensor.
