The magnified screen makes shooting the Olympus TG-3, TG-4, TG-5 and TG-6 much easier, specifically in super macro. The loupe-style viewfinder with a magnification factor of 2.3x cuts out the glare that is often quite disturbing when shooting in water with lots of sunlight. The magnifier snaps directly and securely onto the back of the housing, replacing the existing screen hood. The focal length of the eyepiece can be adjusted to get it dialed in exactly to where your eyes focus best. Weight: 205g on land, 99g underwater.
