@GutterPump: can you take a flat field image? That is, an image without a lens, but with a piece of paper instead,
like this. It should be exposed to the right, but not clipped.
Additionally, can you take a bracketed image at the following settings?
- Subject: a blank out-of-focus wall, or anything else that looks flat without details (not critical, but the scene must be perfectly static)
- Movie mode, ISO 100...400, 1/100, image exposed to the right
- Advanced Bracket: 2 frames, 1 EV spacing, 0++, 1/100 ... 1/50 (that means, Tungsten lights in PAL land are fine)
- Silent Picture: simple (any file format is fine)
- Intervalometer: enabled (to avoid any camera motion), stop after 10 frames (it won't work from the first try).
I just noticed a bug with bracketing + simple silent pictures: in LiveView I need to wait some more after the exposure is changed. That's why I've set the intervalometer to stop after 10 frames - to work around this bug. Please upload only a successful pair of images.
The ratio of these two images (ideally 2) should reveal the stripe pattern.
Related: is there anyone who can consistently reproduce the vertical stripe problem in H.264 with crop mode enabled? I might have a fix for that as well, but I have no way to test - my camera shows absolutely no sign of vertical stripes...
