Almost afraid to ask because this could be a real dumb question-- but here goes: If you google "SD car extension" a few small cable devices come up right away. These are basically a stretch of ribbon tape connected to a female SD card socket and a male SD card docking element.
I could visualize an item like that carefully wrapped along the side of a flash bracket. or on the legs of a tripod (near the camera with plenty of slack for mobility).
Cost seems to average less than $30 USD.
Anything flat out wrong with that approach? The only thing I can think of would be a safety sensor in the D800 that won't allow shooting with the card slot cover open. I checked the manual and see no such warning.
The WT-4 Wireless runs more than $700 USD and if you can afford the D800 you can probably afford it-- but I'm thinking of someone who rarely has the demand for wireless shooting and has already strained the budget with extra goodies for the D800. ---Tom
