Separated at Birth?
What is a little surprising is the size comparison to the K-01. The Pentax is clearly larger, but not significantly so. In other words, the K-01 with the DA Limiteds will fit in the same bags the Olympus will fit into.
With the Panasonic 25/1.4 shown and the built in EVF, the OM-D is arguably larger than the K-01. But again, we're really talking about millimeters, which is nominally nominal.
