Re: Canon 50mm 1.2L HELP!!!

For what it's worth, when troubleshooting over the phone, we'd always ask you to test a "faulty" lens on another body, if you have one available, just to rule out the possibility that your body might be sending incorrect information to the lens, or that it's a wonky setting. 


We'd also, usually prefer for you to send the "faulty" lens along with your camera body so that we can reproduce the situation not only on our precision calibrated equipment, but also on your equipment - again, to rule out every situation. This will often prevent a lot of shipping back and forth of equipment, and take much less troubleshooting time - I used to telll people we like to test your equipment with your equipment, then we test your equipment with our equipment, and see where the faults lie, then we take it from there. 


Far more often than not, if just a lens is sent, we put it on our precision testing equipment, and nothing seems to be wrong. We double-check it, verify everything, and then send it back. When the problem pops back up, we have to have everything sent back in and start from square one.
