This is a fabulous site. Thanks for sharing. Do you know it's reliability?

Checkout this comparison tool on The Digital Picture. It allows comparing lenses against each other. In the center the 70-200L f4 and f4 IS are really close at 200mm. But the mid frame and corners are much better in the f4 IS. It is a newer design and has improved optics along with the IS (which really is good for 4 stops).

I just got an f4 IS and it is definitely better (sharper) than the non-IS. And it is also sharper than the much more expensive f2.8 IS. The store didn't have any of the f2.8 MK2s yet so I couldn't compare with it but I'm guessing the MK2 is at least close to the sharpness of the f4 but at almost twice the price.
