I'm going to be travelling for 6 weeks in Australia with my GH3 later in the year and naturally I want to take lots of photos and video to document the trip. I reckon I'll be filling a 32gb SD card about every 3 days so, mostly with video. Therefor I'd need 15 32gb cards for the trip. The problem with that, is that as I don't envisage ever being away from a computer for that length of time again foreseeable future, buying so many cards would be a waste. If I had a laptop I could simply transfer the files to the laptops hard drive, unfortunately I don't own a laptop, however I will be bringing an Ipad. So I'm wondering, is there such a thing as a device that would allow me to transfer photo and video files from an SD card to a portable Hard drive, perhaps using the ipad as some sort of hub?
