I am running Adobe LR 5.5 with Raw 8.5, shooting with canon 5d Mrk iii. When I import my images they become corrupt after image previews are completed. The image thumbnail from the camera looks great until processed in LR or Bridge. The corruption is visible lines of red, blue, green or yellow and sometimes covers the entire picture.
This is a hardware problem. It could be the camera card, the card reader or USB cable, the hard disk or even memory.
You need to isolate the problem by changing the hardware used to see if the problem goes away.
I have just realized that the issue doesn't occur when I use Delkin Devices CF 700X 16 GB cards, but it has been occurring with my expensive Sandisk Extreme Pro 32 GB and SanDisk Extreme 16 GB cards. Should that have any cause to my issue?
Yes, if the card is corrupted somehow
