>>3911929>PEN-EIt's the Pen E-PL8.
There are other Pen models out there, some feature an accessory port for an EVF.
The most recent Pen camera is the E-P7, a 20mp camera with IBIS but no EVF or accessory port.
My advice is to obtain the OM-D E-M10 Mk IV. It's 20mp, has IBIS and has a built in EVF. It's not much bigger than a Pen camera.
