I thought I would have some Friday Fun -- so I tried to use FoCal to calibrate my new TS-E 24mm f/3.5L II. I set up my target perfectly, covered my eyepiece, and set it on a rock solid tripod. As it's a 5DIII, I had to set it up manually and I have adjust the AFMA values myself.
Something's not working, though. It won't AF at all, and I worry the USM motor might be fried. I guess I'll have to move on to calibrating my Zeiss lenses, but can someone help?
