Romy, you'd be hard pressed to tell any IQ difference between the old and the new 400 f/2.8 IS, when bare. However, with 2xTC MkIII, I see somewhat better resolving power with 400 f/2.8 IS MkII, although the MkI is not that far behind.
Looks like Canon did their job well on the II, Peter.
BTW, I've shot many copies of the 300 2.8 IS (older one), and IMHO the old 400 IS is noticeably sharper than its shorter sibling (particularly with 2x TC), despite what Canon MTF charts say. Is that your experience as well?
Yes, Romy, I am on my 3rd and the best copy so far of 300 f/2.8 IS MkI, but my 400 f/2.8 IS MkI had just a bit more "bite" to it. (I say "had", because a month or so ago I sold 400 MkI following the orders of my better half. )
