    Fotodiox Pro Lens mount with aperture iris
  

*by P***W on Reviewed in the United States on January 14, 2013*

This is a wonderful product for attaching your AF Digital Canon Lenses to a micro four thirds system.  The build quality is excellent and the aperture ring is very fluid, with more than enough blades.  The one draw back is that the ring is labeled 1-7, with the iris closing well beyond the 7 point.  It would be nice if it told you what aperture you were shooting at, but for experienced shooters, it's really not that much of a problem and is very easy to approximate.  I would recommend this to anyone who was looking to attach their digital Canon lenses to their micro four thirds system, it has served me very well.

    The Fotodiox adapter is necessary for me (I shoot with EF lenses on a BlackMagic Pocket Cinema).  My concern was from some of the reviews indicating that the it is difficult to remove from the camera, but I haven't found this to be true at all.This is the perfect alternative to the much more expensive metabones speedbooster adapter.You can see some of the video work using the Fotodiox adapter at [...].The important thing to understand though is why this adapter costs hundreds of dollars less than the Metabones Speedbooster.  This adapter will not allow for the electrical signals from the camera to the lens that allow auto focus, camera-controlled f-stop and image stabilization.With this adapter, everything is manual.Also, it adds to the crop factor so your 50mm will be something more like a 75mm.The only time I've had a problem with this was when I tried using the 11-16mm Tokina lens.  I couldn't achieve any focus at all.

    Works well
  

*by N***S on Reviewed in the United States on April 18, 2013*

The adapter works as advertised. I've used it with various Canon EF lenses and the results are good. Best results with the 50mm 1.8. The only problem is that often the lenses weigh more than my Olympus OMD, defeating the purpose of having such a brilliant, easy to carry, heavily-specced camera. If you want the best manual focusing get into focus peaking on the OMD, available by using one of the Art Filters plus Raw.
