1D Mark IV Focus Tracking
Kevin Krows, Photographer
Forsyth | IL | USA | Posted: 7:05 AM on 04.09.12
->> Have any of you experienced continious focus tracking even after you have released the AF button on the back of the camera? Seems to happen only on my 2.8L 400mm in AI Servo mode. 2.8L 300, 70-200, 24-70, 16-35 are fine

I've checked my custom functions etc., have sent both camera and lens to CPS, and it still happens.

Just wanted to see if anyone else has had a simular experience.

->> Just experienced this the other day for the second time. I was freaking out thinking I was pressing something but looked at both hands and the camera and there was no contact with the camera (or lens), though it kept tracking. Strange. It happened before, but I just figured I was pressing something (even though I knew I was not).
So, Kevin, did you find an answer for this? Is it still happening?

->> Yes. The answer is 1DX. CPS could not resolve the problem after 4 attempts (which also included me sending in all of my lenses).

->> My Mark IV did it intermittently. I found out my AF-ON button was sticking. It was a $148 repair bill after a 30% CPS discount.
