I have just noticed this feature on my Pro’s menu but I don’t understand what the manual says about it. I’m hoping someone can explain what it is supposed to do.

It seems clear enough that this feature is designed to automate the process of taking multiple shots but there is already the “Mult Picture” feature which does this. It would seem that the only difference between Mult Picture and Shutter Teach is that the interval between successive shots is fixed by the firmware in the former case but user-definable in the latter.

Is that right? If so, when would that be useful?
