When you're doing AF Micro Adjust on the the Sonys, what target distance do you use?
I'm working on a Zeiss 135mm ƒ1.8 and find that the required adjustment varies quite a bit with target distance. I started with the target about 6 feet away and it needed +2. But with the target at 20 feet, I need -10. Is this kind of variation typical?
I'm shooting it wide open. Should I stop it down a bit for calibrating?
