So my LC-A meter is either waff or my stop watch lies to me. I process all my own film and i have the temps and time down to a T! But when it comes to this camera and using a slide film that i Xpro it always blowouts! I even rate the film at 200ISO to purposely underexpose it and it still blows out! I think i may stick to c41 films in the LCA and leave the xpro to my EOS-1N that has a fantastic meter.
