I know we have to take the Amazon mirrorless ranking (Click here) results with a grain of salt. That said I noticed something I didnt’ expect. The Olympus E-M1 has never been surpassed by the so praised Sony A7-A7r cameras. The E-M1 constantly ranks above them even now that the A7r is in Stock for the first time.
Olympus has done it right with the E-M1. Hope they can repeat the success with the new OMD camera that is going to be announced soon!
