ISO Expansion?

[jackedwards]

So canon has the ISO expansion feature on teh 5D and many other models if not all. My question is this, does turning on the expansion affect any of the other ISO qualites? I dont see why it would but im curious. And if not why not just group it all toghther?


Cheers

It does not affect the "normal" ISO settings. The reason they're not grouped
together is that there might be times when you wouldn't want to set one of
them accidentally as they do entail a quality penalty (even if very slight, as is
the case of the 5D).

That makes sense. Thank you!
