I picked up a copy of the 400mm DO II lens a few months ago. I have used it everyday for the last few months.
Sharp as a tack even with T.C.\'s. Amazing IS. It is so light and easy to use. For BIF it is really good.
But, I have put it aside at this point, much preferring the heaver 500MM II lens.
The OOF background on the DO can rear it ugly head and is very hard to fix.
Color fringing is much worse than my 500mm lens.
The all around image quality I get withe the 500mm lens is worth the extra weight IMO.
My lens doesn\'t have color fringing or BG issues, it performs exactly as my 600 II and 500 II. I suggest you send your lens and TC\'s to Canon for evaluation. either the lens or your TC\'s are defective.
Note that the harsh back ground in the old lens came from the air gap between the DO elements that causes scattering, with the MKII lens the DO elements are bonded so this issue doesn\'t exist anymore.
