The spot focus on the telephoto's on the 1D IV seems like an almost have to have button, it seems to me that the AF area is much larger on the 1D IV single point than it is on the 5D and 7D. I have been using it alotto focus on bird in the bush.

You are correct, unfortunately the MKIV doesn't have a separate Spot AF button, other than the one you mentioned on the AF-Stop button on the Super-telephoto lenses with IS. We're all hoping that a firmware update will rectify this omission in a future update.


However, even though the Spot AF indicator on the MKIV is the same size as the Single AF indicator. The Spot AF covers an area approximately equal to its actual size, whereas, the Single AF indicator, comprises an area approx. double its own size.
