The OM-D EM-5 coupled with the Panasonic 100-300 is my walk-around wildlife kit. Not as good as my Canon 5D MIII and 500 f4, but so portable I get many shots I would otherwise miss.
Perhaps everyone else knows this but I just opened my November issue of Popular Photography on the first page is a 2-page spread advertising the E-M1 with an image from our very own Diego Garin Martin. Known here as Dukenukem. Diego, I knew Olympus was using your image for advertising but this is the first time I have seen it in print. Congratulations! Keep up the good work.
