I saw this photo on the National Geographic website and I thought to myself - with the smaller sized sensors to that of a Canon 1D-X or a 5DMKiii - is this kind of depth of field, at that distance, possible to do with let's say, my OM-D E-M5? I imagine with the right adapter and lenses it would be, but I don't know. Any thoughts on kit set-up or technical limitations would be great. What would be amazing if anyone has taken a shot with similar depth of field and to share it here! Thanks.
