SO my lens is back , and i did some more serious tests, and send back a mail to canon.

I did the test on a tripod.

The people with the problem if you do a test a f 4.5, 1/5 and keep you eye on the view finder, can you see that the lens is shifting, moving toward the bottom right ?. Do it on a tripod.

The people with correct lenses could answer also or those that have been repaired

Also do it at f 4.0 and you should see no move.

As mentionned by another poster, if you do this test at f 4.5 and keep the deep of field preview button pressed you won't see this movement.

Is this normal ? I don't think so, because i did the same kind of test on my other lenses with IS and no problem. I'm waiting the answer from canon
