The NEX-7 uses a 24MP APS-C sensor shared with the SLT-A77, that sits behind Sony's all-electronic E-mount. As you can see the mechanical shutter is open by default - something that SLR users may find disconcerting, but we've had no problems with in practice over several years of using this type of camera.
The NEX-7's built-in flash pops up out of the top plate, released by a button on the back. It has a guide number of 6m at ISO 100 and can be used with lenses as wide as 18mm.
Slightly disappointingly, it can't be used as a commander for wireless off-camera flash. It's also rather close to the lens axis, which could cause shadowing with larger lenses such as the 18-200mm.
One cute, but undocumented feature is that the flash can be pulled backwards for bouncing off a ceiling, giving more flattering lighting.
This isn't an official feature, so use it at your own risk.
For users looking for more control over lighting, the NEX-7 has a Sony/Minolta hot shoe on top to take dedicated flash units such as the compact HVL-F20AM or the more powerful and fully-featured HVL-F43M.
The F20AM can also be used as a wireless flash trigger when working with off-camera units.
On the front of the handgrip, directly below the shutter button, is a receiver for the RMT-DSLR1 infra-red remote control (that's also compatible with certain Sony DSLRs and SLTs).
The orange LED lamp also visible is the AF illuminator, to assist focus in low light situations.
The NEX-7 sports built-in stereo microphones for movie recording, hidden behind tiny holes above the lens mount. One mic is clearly visible here below the 'N' of Sony, but the other isn't, being almost completely hidden behind the mount.
The depression in the body on the right of the picture is purely cosmetic, to provide symmetry to the camera's looks.
The connectors are arranged vertically down the left side of the body, behind a pair of hinged plastic doors. From top to bottom we have HDMI out (type C minijack), USB (mini-B type), and a 1/8" socket for an external stereo mic - the latter behind it's own door. Note that there's no cable release option.
The base of the handgrip plays host to the combined battery and memory card compartment. The NEX-7 uses the 7.7Wh NP-FW50 Li-ion battery, shared with other NEX models.
The card slot is very close to the door, meaning you have to grasp the card by its edges to remove it. This can make getting the card in and out a rather fiddly process.
The tripod mount is placed centrally with respect to the lens axis. Because of the NEX-7's ultra-slim body and tilt screen, there's very little real estate on the base plate around it for a quick release plate to grip.
On the plus side, the mount is sufficiently far from the battery/ memory card compartment to allow them to be changed with the camera on a tripod.
