I ran across a Canon Pellix QL with a 55 f1.2 pretty cheap. The lens is in excellent shape. The body has some issues with faster shutter speeds. 1/250 and above are affected. At 1/250 I am getting some shutter capping and at 1/500 and 1/100 I am getting blank frames. Anyone still service these old Pellix's. Thanks in advance for any help.
