The E-P5 uses the same 16MP Four Thirds format sensor as performs so well in the E-M5, E-PL5 and E-PM2.

The Micro Four Thirds mount means that it's compatible with lenses from Olympus, Panasonic and a growing number of third party manufacturers. Overall they make up the most compelling range for a mirrorless system right now.
The E-P5's little pop-up flash has a guide number of 10 at ISO 200. Unlike the units on several similar cameras, it can't be pulled back and manually bounced for better lighting. However it can be used as a wireless controller for off-board units such as the FL-300R and FL-600R.

The flash is released by a prominent button on the back plate, which is easily pressed accidentally.
The E-P5 uses Olympus's standard hot shoe and AP2 accessory port, so as well as the new VF-4 it can also use the older, lower resolution VF-2 and VF-3 electronic viewfinders.

It also accepts a number of other plug-in accessories, including the MAL-1 Macro Arm Light and the the PENPal bluetooth module (although the E-P5's Wi-Fi makes this pretty much redundant).
Perhaps the most useful AP2 accessory is the EMA-1 stereo microphone adapter, which comes bundled with the ME-51S microphone shown here (and an extension cord).
The camera's connectors are under a sprung plastic cover. At the top is a USB 2.0 /AV Out connector that's also compatible with the RM-UC1 cable release.

Beneath it is a Micro HDMI Type-D cable for video playback on your TV.
The E-P5 uses the same BLN-1 battery as the E-M5 (and therefore different to previous PENs). It's a 9.3Wh unit with a CIPA-standard battery life of 330 shots.

The SD card shares the same compartment as the battery. As well as standard SD cards, the E-P5 is compatible with Eye-Fi and Toshiba FlashAir Wi-Fi cards.
The tripod mount is slightly offset from the lens axis, and situated towards the rear of the body. There's a fair amount of space between it and the baseplate compartment door.
