Getting strange lines in my photos. Problem wasn't there yesterday and was there on every photo I took today. Ugh! I've had my P4 for about six months and have used it extensively without a problem. My firmware is up to date. There isn't so much as the smallest nick on my P4. Never had any crashes or any damage whatsoever. The lines are very fine and run vertical and are green, white and red/purple. It happens at all ISOs. I always shoot RAW, but I tried JPGs and I get the same result. DNG clearer doesn't remove lines. Lens is perfectly clean. I tried two different memory cards and tried two different cables on my RC. Nothing makes any difference. Any thoughts?
