The H4D-60 now features a digital spirit level function on the rear display. This function is easily activated with a simple press of a button or via any of the programmable user buttons. This handy feature allows accurate alignment and level readings even when using the camera handheld. The spirit level reads both the vertical and horizontal positions (pitch and roll) of the camera and can be calibrated by the user to suit any situation (predetermined angle or tilt, etc.)
