X10 sensor 'streak'...

An extreme 'levels adjustment' reveals more widespread streaking (albeit of much lower severity)...


(Extreme 'levels' adjusted)

...it almost looks as if the sensor has been physically 'scrubbed'.

The reason I suggested the 'dark frame' test, was because I had recently returned an X10 due to a very similar issue, although of a much lesser degree than yours.

The problem on the X10 was pretty much invisible in normal use - I only noticed it while doing some noise testing/measurements.

The 'streak' on the X10 sensor produced a 'very slight dark streak' in a light subject/background, but conversely a 'very slight light/increased noise streak' in a 'dark frame' (no light).

N.B. Both the frames below are quite heavily adjusted (especially the dark frame), to make the 'streak' more clearly visible, it is just about invisible in a normal unadjusted image...

P.S. My advice to anyone thinking of testing their XS-1 or X10 for similar sensor streaks - it really is probably best not to - if you are otherwise happy with your camera, it's probably better not to go looking for problems.
