Very positive experience with OMD + EYE-FI 16gb Pro 2X

I set the software and card in direct send mode - meaning in the absence of a WiFi network it'll search, connect and send files to your device.

Initially U want your device to be active and the app running.

It has taken anywhere from 15 secs to 30 secs to see the first jpg going, but after that initial run, assuming you are frequently shooting, the photos just find themselves there.

If hr device goes into sleep mode, the file transfer restarts at the last sent jpg when it's active again - assuming your camera is active also.

I set my jpegs to small so sending less than 1m per photo is pretty fast. Ymmv.
