|In a significant upgrade over the GH2, the GH3's viewfinder is an OLED 1.7 million dot unit. Directly beneath the eyepiece you can see a sensor for automatic switching between the EVF and rear panel display. A diopter adjustment knob juts out slightly from the right edge of the rubber eyepiece cover.|
|The GH3's pop-up flash is aligned with the center of the lens mount. It has a relatively low guide number of 13m at ISO 200, but does offer 24mm (equiv.) coverage to match Panasonic's recent 12-35mm F2.8 lens. You can of course attach a more-powerful external flash via the camera's hotshoe.|
|The GH3 is among the more button-heavy cameras you'll find in any class, with four sitting along the camera's top plate alone. A deeper handgrip design has allowed for a second control dial just behind the shutter button.
The power switch juts out from the mode dial, and you can see status lights for both power and Wi-Fi connection.
|Three of the camera's five customizable Fn buttons are located to the right of the rear OLED. A 4-way control dial with central button sits here as well. Above the 'DISP.' button you can see openings for the GH3's speaker.|
|A fifth Fn button and playback button sit to the left of the EVF. Above them on the camera's shoulder is a drive mode dial, which replaces the AF mode dial found on the GH2.|
|The GH3 has a dedicated drive mode dial, as opposed to the switch operation found in the GH2. A flash PC sync port sits below it on the camera's front plate.|
|A 3.5mm mic socket (versus 2.5mm on the GH2) lies on the camera's left side, eliminating the need for mic owners to use an adapter. You can also see the flash pop-up button located on the viewfinder housing.|
|The GH3 sports the familiar Panasonic thumb dial. With Panasonic's decision to devote the camera's second function dial to drive versus focus mode, a three-position focus mode lever now surrounds the AF/AE lock button, in a design reminiscent of the company's old Four Thirds SLRs.
The movie record button has been moved from the top plat to the rear of the camera.
|The AF assist lamp has been re-positioned - much more sensibly - to the right of the lens mount where you're far less likely to inadvertently block it with your finger.|
|A hotshoe sits atop the viewfinder housing. On either side of it lie the camera's stereo microphones.|
|On the left hand side of the camera is a combined USB/video out connector, and a HDMI port that can be used to connect the GH3 to a monitor or external video recorder.
Above them is a second rubber-flapped door concealing a headphone socket for audio monitoring.
|The GH3's SD card slot sits behind a sprung plastic door on the handgrip.|
|The door to the GH3's battery compartment lies underneath the handgrip. The GH3 uses a high capacity 14Wh Li-ion battery pack (Model DMW-BLF19PP)|
|The camera's tripod socket is aligned with the center of the lens mount, positioned far enough from the handgrip to allow for a battery change when the GH3 is attached to a tripod plate.
The electronic connectors (shown here with cover removed) are for communication the GH3's optional vertical grip.
