I import products by sea frequently and it takes 5 days to get here. [snip] [shipping the 1Dx] would take under two weeks.
From where do you regularly import products by sea? Unless you have a private fleet of bluewater hydrofoils, five days is wildly unrealistic for bringing containers to the US from Asia.
The great circle distance from Tokyo to San Francisco is ~5500 miles. To make that trip in five days, you'd need to average about 46 MPH. Container ships typically cruise at 25 knots, which is a little less than 29 mph. I'd be fascinated if you can show me a container ship that can make anywhere near 46 mph.
It takes about eight days to go from Tokyo to San Francisco at 25 knots, so your other estimate--two weeks door to door--seems much more reasonable. However, many container ships have begun to cut speeds to 12 knots for the fuel savings:http://m.guardian.co.uk/environment/2010/jul/25/slow-ships-cut-greenhouse-emissions?cat=environment&type=article
Maybe I misunderstood your initial post, but the idea that 1DXes will cross the Pacific in five days is silly. It's just as silly, in fact, as another poster's speculation that those cameras have already begun a three-month crossing.
