The Manfrotto 303 panoramic head also declined under the code name MH057A5 in the catalogue with a more recent L Bracket (there are two other models: 303+ and 303 SPH ) is thus a cylindric head. It doesn’t have any tiltable stage on its vertical arm. It is thus perfect to support quite heavy bodies because the center of inertia of the body is in the axis of the vertical arm and not shifted at the back as with a spherical head. The stages are of standard dimensions as we’ll see later.
