I'm renting a Sony A6300 to see if I want to switch from my Canon to a mirrorless system. It did not come with a USB cable for uploading, so I just popped the card into my Canon and used that cable. The photos I'd taken with the Canon came up as RAW previews and the jpgs I took with the Sony came up. But none of the RAW shots had previews, just black placeholders. I just want to confirm what I think is the case. I've resisted getting the CC version of LR. So does this mean that I need to switch over to Adobe CC Lightroom in order to see my photos (and any future ones if I choose to go mirrorless)? I'm hoping that this is the only problem. Thanks!
