Is there any camera or accessory that would let me download the SD files through wifi or bluetooth, thus not having to remove the camera to extract the SD? . Still, there
I understand that having the wifi or BT permanently on would consume too much power, but there is no need for this permanent connection: you could turn the camera on with a remote controller, then download the files through wifi or BT. Note I am not asking for a system to dowloand the files from a distant place, just want to avoid having to 
touch the camera. A few meters would be enough.
Perhaps somebody has come out with a DIY solution?
Thanks,
