PBednar
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.
