Bridge cameras continue to be one area of the compact camera market which remains buoyant in an otherwise declining arena. The HX400V is one of the larger bridge models available, closely resembling an entry-level or even enthusiast DSLR/T - in overall body size at least.The key selling point of this camera is its massive focal range. It keeps the incredible 50x zoom of its predecessor, the Sony HX300V, which equates to 24-1200mm in 35mm terms. Impressively it also manages to have a maximum aperture of f/2.8 (at the widest point of the lens), rising to f/6.3 at the telephoto end. Outwardly, much of the HX400V remains the same as the camera it replaces, such as the three inch tilting screen on the back of the camera. Inwardly though, the HX400V has seen some key improvements which should equate to better image quality.
