It will be soon possible to send a photo from an SD card directly to a smartphone or iPad. No need for a separate wireless router or any other device anymore.
This is really great for shooting outdoor.
In my case, using a P40+ on a Cambo for architecture, and 'easily' reviewing the shot on my iPod should be really, really great.
An SD card can be used on a Phase back with a Compactflash card adapter.
A metal free adapter gives good results (no signal distraction).
Normally raw files ca also be sent the same way, but duration will be longer (too long ?) and files won't be usable on iPad / iPhone.
So the missing link, if I got it well, is the 'shoot raw+jpeg' function on the back (as Pentax does).
As Phase and Hasselblad are already generating jpeg files for displaying on the back, it shouldn't be that complicated to firmware update the backs to record a jpeg version on the memory card too.
If all that is correct I hope someone at Phase One understands the outstanding added value of such an update !
