SUPPLY AND DEMAND, THE A LENSES ARE NOT ONLY MORE DESIRABLE DUE TO FUNCTIONALITY, THEY ARE ALSO RARER. JCO

Hi, OK, obviously I do know that A-lenses have an A-modus, allowing the camera to set the aperture (shutter-priority modes), while M-lenses always require the aperture to be set on the lens. But being in persuit of a 50mm f/1.4, I notice that the A-model is priced at least twice as high as the M-model, if not more. Looking at the mechanics of the diaphragma, I wonder if an A-lens is that different, apart from the electronic contact that probably doesn't do anything more than telling the camera whether the A-mode is on or off. And I also assume that the 50mm f/1.4 M and A are optically identical? So is there any objective reason for the price difference, or is it just the game of demand and available quantity that sets the price?
