Question, why didn't you use a slightly lower ISO and increase the shutter speed? I would have thought with the 14mm on a 5D you could should for at least 45seconds without trailing? Or alternatively stop down the aperture by a stop and increase the shutter?

Hi Mo
Even with the 14mm on the full frame, any more than 30-35 seconds and you start getting trails (when you zoom right in).
The aperture was as f/2.8, the fastest the lens will go. We want it wide open and capturing as much light as possible in as short a time as possible - that's also the reason for the high ISO.
The 5D Mk 2 handles ISO3200 easily, and the resulting noise/grain is certainly not offensive, and easily handled well by Topaz De-Noise or one of the other de-noise plugins or programs.
Keeping the shutter speed as short as possible is the aim.
