Just a thought, open up the back and switch from Panoramic to Standard, you should see two black metal blades slide across the film gate to mask it down to the regular 24mm x 36mm dimensions. If these blades don't appear (and snap back when you switch to panoramic) then you've got a problem.
Thanks for the reply. It ends up that the Panoramic switch is faulty and it's already in the shop for a repair. Thanks again.
