You may very well be correct (on cause), but effect is eerily similar to non-LV mirror \'brush\' and given that it\'s always in same location and only with 5DIIs (so far)...
There is possibility is shutter-related, but how non-chipped lenses would effect physical shutter timing I have no idea. I\'d bet if it\'s a firmware issue - it\'s related to something mechanical in the LV mechanism. Now how that would vary between the 1Ds3 and 5DII given they probably share a lot of the same LV firmware code, you\'ve got me.
Be interesting to see what the final determination is.
