The LUMIX FZ300 features a splashproof / dustproof rugged design with tight seals on every joint, dial and button, so it stands up to harsh weather conditions and challenging environments—from a marshy jungle to a windy desert. That moment you want to remember can occur at any time, and Panasonic's exclusive 4K PHOTO technology uses 30 frames per second in high resolution 4K Ultra HD Video to extract them as photos. You'll never miss THAT MOMENT again. Panasonic's Depth-From-Defocus (DFD) Auto Focus (AF) technology instantly calculates the distance between foreground and background and quickly brings the subject into focus in one fast, continuous movement. In addition, continuous focus stability is enhanced when shooting video. The 12.1-megapixel High Sensitivity MOS Sensor in combination with the Venus Engine excels in diffraction compensation, yielding images that are crisp and free from artifacts associated with small aperture settings.
