that won’t work…because neither the body or the storage device has the software to do it. You can either copy to an iPad and then copy from there to a drive and delete from the iPad…or you can get a powered hub to plug into the iPad and then a card reader (or perhaps you can hook up the body directly, but I haven’t tried that)…and a storage device to the hub and copy from the body/card reader to the storage device without any storage on the iPad used. Alternatively…just get a bunch of cards. If I was going on a 20K+ trip to Africa…I could copy them from cards to laptop and thence to a pair of SSDs…and would also have enough cards that erasing them wasn’t needed for the duration. I may be paranoid…but that doesn’t mean they’re not out to get me. Others here have done this card to iPad to drive routine and it works…but me…I want to use LR and do some sorting on the trip time permitting so when we travel we carry 2 iPhones, 2 iPads, and my laptop between my bride and I. One can also leave the copy on the iPad for another backup…assuming you have enough memory available on the iPad…but with a high MP body and a bucket list trip that could become an issue.
