Daniel; a quote from the review you linked,

"As you can see from my samples, I mostly stuck with the Canon Mark III on this trip. Mainly because of the difficulty I faced with Nikon D800's poor LCD Live View performance in low light. For my photography needs, this was the Achilles' heel of an otherwise superb camera."

Do you see this as an issue?

Fred Miranda was not to positive on the Nikor lens he had either.
