Re: IS your KM7D showing banding on the left side of the sensor at high iso?

So, I downloaded your images and played a little.
It seems it is happening in the blue channel only , at ISO1600 and 3200 (you can see it at 100% not on the thumbnails) . When the signal in the extreme right columns of the sensor is amplified, the blue channel get a little over exposed.
I really don't know what it can be. could be the aplifiers in the CCD? or the coating on the sensor? or the bandpass filter?
Good thing is: it can be very easily corrected.

1600 iso, blue channel, contrast pushed in the selection on the left.

3200 iso, blue channel, contrast pushed in the selection on the left.

It's just some glass, some silicon and magnesium. It isn't a religion.
