Going old school
While in really doesn't look a lot like its namesake, which had far fewer buttons and dials, Olympus did preserve some of the aesthetic.
Front dial
On the original, this front dial controlled shutter speed; on its digital descendant, it controls color and art filters.
The terrain
The almost featureless top of the original Pen F gives way to the more commonplace digital-camera controls enthusiasts are used to. The shutter button has a cable-release socket, though, as well as a lockable exposure-compensation dial.
Viewfinder
We used to be able to distinguish between the OM-D series and the PEN models because the former has viewfinders and the latter didn't. No more.
Shiny
As is all the rage in premium cameras these days, the dials are made from aluminum.
It's really hard to make the backs of digital cameras look retro. The leatherette doesn't do it for me, but like appliances camouflaged with wood fronts, that's a personal choice.
We welcome the articulated display.
Card slot not here
Sadly, the SD card slot is in the battery compartment, not here; the HDMI and proprietary USB connector occupy this valuable real estate.
Pay up for the grip
Like many companies who design cameras with no grips, Olympus makes you fork over extra bucks to be able to hold the camera comfortably.
