You can animate them. But it does not work without problems (I mentioned them after the first daily with new tone mapping came public, it was the first thing I tested). For example, you cannot grab keys in the timeline to move them, you do not get brackets at key positions because it's now an extra non-max interface, Shift-RMB does not create a new key, and keys from old cameras do not transfer anyway (I can understand why and it is tolerable).
Sorry to say, but those issues are that typical animation ignoring attitude Corona development (and QA, which is worse) always had. I have countless open reports about keying, animation and parameter block issues generally. And there is no movement at all.
Quicktip: If you want to animate camera override tonemapping stuff, do not use any old cameras. Create a new (v8) one. So be sure to update any startup scenes with a camera inside.
Good Luck
