There are several cameras giving half-frame for the "normal" 35 mm film - that is 18x24 instead of 24x36 , e.g. Olympus-Pen. If its lens is marked as "28mm" - does it mean its angular view corresponds to 55mm for the common 35 mm film camera, or the 28mm is the equivalent focal length (so it is 14 mm really)? Thanks in advance.
