The Panasonic GH3 is a pro-caliber mirrorless camera for the Micro 4/3 system.

The GH3 features a 16MP Live MOS sensor and an advanced Venus Engine processor. Its normal ISO range of 200-12,800 gives you the flexibility to shoot in any lighting condition, and Panasonic’s highly responsive Light Speed autofocus system provides 240 fps AF-sensor readouts. Full-area focusing lets you select any area within the frame to set an adjustable-sized AF point, supporting continuous focus for both still and video shooting.

While the Panasonic GH2 offered a great amount of video flexibility (some of which was not official), the GH3 offers greatly expanded control. It records Full HD 1080p video at up to 60 fps, and shoots natively in MOV format with your choice of 50 Mbps IPB or 72 Mbps All-I compression formats. There’s built-in timecode functionality with a count-up system with Rec. Run/Free Run option, as well as a Drop Frame/Non-Drop Frame mode.

The GH3’s seamless file generation and advanced heat-dispersing design minimize recording-time limits, allowing extended continuous recording without interruption or overheating. The camera features multiple input options for expansion capabilities, with a mini-HDMI port that supports both monitor loop-through and external recording (uncompressed 4-2-0), and 3.5mm mic and headphone inputs for advanced audio functionality with in-camera level adjustment.

The GH3 is larger than its predecessor, but it’s gained sturdier, weather-sealed, magnesium-alloy build. The 1,744K-dot EVF and 614K-dot free-angle rear LCD—both of which are OLED—work in tandem to provide high-quality monitoring. The GH3 has a pop-up flash (GN17 @ISO 200) for quick fill, a standard ISO hot shoe for external flash units, and a PC Sync input for studio strobe use. The GH3 is also the first Micro 4/3rds camera to have built-in Wi-Fi functionality, which allows both remote camera control and image backup to an Android or iOS smartphone/tablet via Panasonic’s dedicated app.

The GH3 writes images and video to SDHC/XC memory cards, and uses a rechargeable lithium-ion battery that’s rated for approximately 500 shots per charge.
