I've had trouble transferring video onto my IOS devices... It's slow, connection often breaks, etc. The fact that there is no card slot on the devices does not help at all. I've purchased a Sony portable wireless server from Amazon. My model is the WG-C10/NWC1 This is very helpful. It creates a wireless wifi "virtual card slot." Along with the simple app, you can transfer photos super quick, and video reliably fast to your iOS device. I believe, but not attempted, that you can also hook up a flash drive and even an external USB drive to this and transfer your images from the memory card to the drive. Look it up,I think it might be helpful. Didn't cost all that much. Cheers!
