I now own two Olympus Pen E-P5s: one silver with the best-of-breed VF-4 electronic viewfinder, the other white with a compact VF-3 viewfinder. Each time I hold one of my E-P5s, I feel as though I'm a rich man holding a vintage jewel. The camera's physical controls are amply provided and well-placed. The E-P5 is as capable as a midrange OM-D. It's also more versatile: You can remove the (optional) viewfinder to pack small or shoot more discreetly.
While the E-P5 lacks the Pen F's panache and built-in viewfinder, it has a built-in flash and costs about a third of price of a used Pen F.
Moreover, the E-P5 weighs only 2 or 3 ounces more than a contemporary Pen Light: An E-PL7, E-PL8, or E-PL9. The E-PL7 and E-PL8 lack a built-in flash; the E-PL9 won't let you use an electronic viewfinder. And no E-PL has the E-P5's dual control wheels. All in all, the E-P5 is a stand-out bargain.
