Every time photo shot in D-Log on camera X5, the first is overexposed. I use the S mode and the first picture is taken with the longest exposure time that the second and the others. Back to record a video and when I take another picture is the first new overexposed. See the photos I sent. The difference between them is 2 seconds. The first opening is 1/40 sec and second 1/80 sec. It happens to anyone else?
