Greetings,
I tested the brand new 40D high ISO. This are what it produces. The 1st two are on ISO100, the rest on ISO1600. Shots are taken with continue burst shooting at hi-speed. Anyone faces the same? I bring it back to canon tomorrow.

This looks like the "shot under florescent lighting at the wrong shutter speed" quirk. You'll have to set your shutter speed to 1/60 (I think) to avoid this. Do a quick search or it may be a wasted trip.

Greetings,
You mean I can't shot at any other speed under florescent? This makes no sense. This never happens to my 5D.

If you are using too high a shutterspeed, you'll see the 'flickering' caused by the voltage being a sine wave.
Use a slower shutterspeed.

5D will produce the same.
