Your H4D-40 and H4D-50 will now, thanks to an updated firmware version, be able to get maximum detail and clarity from the 3” high-resolution display. Unlike other high-end systems, this display utilizes the full display area for image viewing, allowing you to see your entire image in full color and resolution. This 61 x 46 mm viewing area (compared with 55 x 41.4 viewing area in other MF systems) makes it much easier to judge the quality and composition of your shot even when working untethered on location.
