Problem with camera or memory cards?
I originally thought this issue was a card issue, as the only time it ever happened was when I was recording on a 32GB CF card; I quit using those cards and now the problem is back, and worse. Most of the shots are okay, but I can't tell by a thumbnail whether the photo is good or not. In Canon's Digital Photo Professional and other viewers, the thumbnails look fine on the computer, and the photos look fine in camera, but when I open the raw file on my computer (either Camera Raw 9.1 or DPP4), it looks like this:
It had started with only the lower right quarter of the photo being affected, but that has obviously gotten worse also. Trying to figure out if it is an issue with the camera or with the cards. Not sure if I need to replace my cards or send the camera in.
Camera is a Canon EOS 5D Mark IV (purchased 11/16); cards are all Lexar professional, either CF or SDHC.
A photograph is an artistic expression of life, captured one moment at a time . . .
