Yes. The only limitation I've noticed so far is that the maximum exposure duration for each individual frame is 30 seconds. With my knock-off TC-80N3 I could do as many minutes as I wanted.

Excellent point! I've woken up lots of times to see my DSLR covered in dew or frost.

What I find so entertaining about it is that every two years or so they get ever so slightly closer. First it was AutoISO... but only in auto exposure mode. Personally, I find that rather useless. Then it was Auto ISO in Manual mode... but not flash. Now with the 5D3 I bet it work in manual and flash... but no compensation.
