First, please let me say I'm not sure where to post this, but I need help. I have an A7 and an A7II. And, I am renting a Sony RxR1. shoot in JPEG + Raw. When traveling, I use a card reader to upload images to my iPad. The first time my images showed up on my iPad like what you see below, I thought it was the reader. But the reader behaved fine after that. Then it happened again with a card from a different camera body. I was told that sharing cards among cameras is a bad idea, so I stopped sharing cards and labeled the cards so they would no longer be used between cameras. Then it happened again -- with the third camera body. Any ideas what is going on? Is it the iPad? the cards? Are my images lost forever? 3 times now-- with 3 different Sony camera bodies-- and with 3 different cards. Please help, and thank you.
