Canon 400 2.8 II non-IS and Mark IV

->> Currently i use a Canon EF 400 F/2.8 Mark II (non-is)
Has anybody got experience with this lens combining with a 1D Mark IV.
I heard some rumors about these slower lenses can get problems with faster (newer) bodies, something like "the camera talking to fast for the lens to understand" Curious what you guys where thinking about this and have maybe experienced issues?

What i do noticed is that the Mark IV has issues with nearly still objects in AI Servo mode.
Like coached on the sidelines just pointing but nut walking or running like players do.

->> I use that combo and have no issues. The only time I have heard of issues was with the original 400 2.8 lens. It was too slow to keep up with faster bodies.

->> I think it's safe to assume that when Canon (or Nikon)develops new products they think mostly forward rather than backward. True, they try to maintain backwards compatibility but only to a certain point.

Lens recognition, incorporated into the Mark III and above, should be a clue that the camera bodies are much more intuitive when talking with each other. I can only assume that communication is more robust and accurate when newer lenses are attached.

Just an observation .... may not be technically accurate however.

->> What I was told by my friend who is the midwest Canon rep was something like this:
The camera bases its performance on what lens it sees is attached. An older lens will have the effect of 'slowing down' the cameras functions (whatever that means) so that the camera doesn't outperform the lens. The newer lenses allow the camera to run at peak performance as it was designed to do.
