My Sony F828 recently produces images with a weird line pattern, faded colors and light pink to purple color cast.
I have no clue what is causing this - sometimes I make a series of about 5-12 pictures, same conditions and nearly same settings and a few of them have this error.
Very annoying if one of the shots you "waited for" is affected by this, but also makes a good challenge to find out what's in it to use them anyway. Same adjustments or filter work, some show in the preview, but when you click OK they don't show in the picture.
Would be cool if somebody knows more about this error. Waiting for an answer from Sony so far and start to find subjects that might be interesting to shoot with this error.
