Received my 1Ds M III back from VA depot repair. Being In CA I stupidly let it travel Ground so it took a week to reach them. They received it Monday of this week and I have it in my hands today as they returned it FedEx overnight per my (polite) request. I am completely OK with this turn around.
Serial 623069.
I suspected AI Servo issues, in conjunction with simply too many OOF shots. Coming from a 5D I have been fighting this issue for a while. So on the work order i indicated motion tracking while in Servo mode was certainly suspect, but in addition, please verify the overall AF system and pieces. And, having just returned from a howling wind-dust storm in Spain, please clean the thing for me.
Too soon to post shots, but I spent the last hour re-doing the Focus Micro Adjustments. Each lens is improved, or another way of saying it is most are less "off".
the 35 f/1.4 is now +5 instead of +10
the 24 f/1.4 is now +10 instead of +16
the 50 f/1.2 went from 0 to +5.
As before, the 135 f/2.0 is dead on 0, and the 85 f/1.2 II as well, at 0 adjustment.
So it is clear to me, before I work this out with some shots, things changed internally. And it is clean as new.
The work order states....
"AF Accuracy adjustment, update firmware."
