The Panasonic Lumix DMC-GH3 Mirrorless Micro Four Thirds Digital Camera (Black) features a 17.02MP Micro 4/3 Digital Live MOS sensor and a 4-CPU Venus Engine, which enable the GH3 to capture high resolution JPEG and RAW stills as well as intricately detailed HD video. The GH3 has been totally redesigned with an array of professional level features including a sealed magnesium alloy body, a contrast auto focus system, Full-Area Focusing and OLED displays for both the rear monitor and the electronic viewfinder. Both the front and rear curtains in the DMC-GH3's shutter system are driven electronically for vibration-free operation. This ensures crisp still-life images and landscapes with no pixel shifting. When it comes to still photographs, the GH3's imaging capabilities are further enhanced by an automatic high dynamic range feature, a newly designed low-pass filter and compatibility with a growing family Lumix G lenses.
