Simply put, the 70-200 MK II is a better performer over the Non-IS and IS MK I.

It better be for that price but he is saying not much difference between mk1 and mk2 IS models but lot more between mk2 IS and non IS one.
The non IS one was always much sharper than the IS one to begin with. Now with mk2 maybe canon bring IS one to the non IS or the f4 IS level.
