One of the much appreciated benefits of shooting in 4K is the latitude those extra pixels afford you for cropping and stabilizing footage that is to be delivered in high definition. While cropping and stabilizing are usually done in post production, Panasonic’s WXF991 can tackle all that, and more, in the camera itself. The camera’s cinema-like editing features allow you to zoom in and out of subjects without changing camera angle, pan across a scene Ken Burns-style or create Steadicam-like ultra stabilized footage all from your 4K file. Taking advantage of these edits means the resulting video will be high definition. If you film in 4K, you’ll also have access to Panasonic’s 4K photo modes, which isolate 8-megapixel still frames from your moving pictures. The WXF991 records 4K video at either 24 or 30 fps via an 18-megapixel 1/2.3-inch backside-illuminated image sensor. It has a 20x optical zoom Leica Dicomar lens with a variable aperture from f/1.8-3.6 and a 5-axis hybrid image stabilization system. Beyond its clever 4K edits, the camera offers an HDR movie feature that captures an alternating series of over and under-exposed frames then combines them into a single, properly exposed HD video with a wide dynamic range. The camera also incorporates a high-resolution, tilting EVF, 3-inch touchscreen display and Wi-Fi.
