The Loupe for SpectraHD 4 allows for optimal viewing the SpectraHD 4 LCD screen by completely enclosing and shading the display. Whether shooting in bright environments, or when shooting with the camera over your shoulder, this loupe makes it easy to see your screen with precision. High quality optics give you a cystal clear view of the SpectraHD's 1280x720px display. A focusable diopter allows adjustment for different eye types, and the optical pieces can be replaced for shooters with stronger eye prescriptions. The loupe can swing up and down, as well as it can be easily and quickly removed.
