Chris, I don't have a F4 but a F601 where the autobracketing is built-in. As far as I understand it, autobracketing and compensation are incompatible with the manual mode. There is a technical problem: you impose a speed and an aperture, what is the camera supposed to do if you ask for a correction? Change speed (as in A mode), change aperture (as in S mode) or both (as in P)? If you still use them in M mode, the only thing that happens is that the viewfinder exposure scale may be bracketed. I.e., the "correct" exposure indication is shifted. If what you want to do is to bracket around a couple of parameters you want to impose yourself, there are two solutions: - work in A, S or P mode and combine compensation (to set the wanted central speed and aperture values) and autobracketing; - work in M mode and bracket manually (I personally find this is simpler and often faster, not to mention less error prone). Hope this helps, Nicolas.
