Are they there in both 16:9 and 4:3 images? I recall that one of the FW updates introduced an issue with horizontal lines in 4:3 images and video. I think it was 1.2.7 for the P3A, but that was quickly replaced with 1.2.8.
Oh sorry I should have included in my original post. P3P with firmware 1.4.0, iPad 2 mini iOS 9. Images look fine on preview but when I download them to my mac the lines are visible. They are dng files
This is super frustrating, P3P is only a month old and hardly have much flying time. Can't believe no one else i getting these problems. i'm out taking all these pictures and when i get home i find that they're all corrupted. those locations are at like 5 hours drive each!
