Panasonic has officially announced the first-ever digital camera with built-in 4K video recording. The Lumix DMC-GH4, previewed as the “GH next” at CES and aimed at the “pro-consumer,” is a Micro Four-Thirds interchangable-lens mirrorless camera. It’s also a successor to the company’s popular GH3 model, which remains in Panasonic’s line. Price and availability will be announced in March, but figure on April and in the $1,300-$1,500 range.
