Just Posted: Our detailed, hands-on Olympus PEN E-P5 preview. We've been using a pre-production E-P5 for the last few days and have had a dig beyond the specifications to discover how the latest range-topping PEN behaves. We investigate the camera's latest features, including its easy-connect Wi-Fi, its degree of customization and its '2x2' dial behavior. We also take a look at how it compares to the E-P3 and OM-D E-M5, and how the high resolution VF-4 handles on the E-P5 and existing models.
