When I try to import photos from my Canon EOS70D into Lightroom firstly I get "Preview unavailable for this file" for all the files on the camera. Then If I check a few photos to import, Lightroom says it is importing but the photos never import and eventually I have to cancel the import. I have tried to import just one photo and this same thing happens.
I don't think it's the cable or the camera as I can import into iPhoto from the camera using the same cable.
Any advice appreciated.
What version NUMBER of Lightroom are you using?
It's ok thanks, I figured out the problem. I have to leave the camera attached to the laptop for some time. Eventually the files all have thumbnails and then I can import them. I was previously trying to import them too quickly.
