Reviews of new 300-600mm Mk2s?

Anyone know of any hands-on reviews of pre-production Canon supertele Mk2s?

Since they are not even shipping yet, I would assume no.

do you need a review? Really? I mean, its kind of a good assumption they're good

There usually are pre-production reviews of Canon lenses from select pros before they ship to the general public. Just one way to whip up interest in the product. I couldn't find any reviews by Googling.

Sure I know they're good. No I don't need a review. Doesn't mean I don't want to read some reviews.

When I read the subject, I thought there was a 300-600mm zoom in the works! That's something I would have goon out of my way to get

I have seen nothing. I cannot believe this is anything more than a way to increase their prices. Those lenses are sharp wide open. There is not a single industry demand for them to improve. With the exception of weight those big guns are all flawless.

me too...300-600mm f/4 would be cool, but given the cost of Nikon's 200-400mm f/4 I'd probably not be able to afford it for a very long time anyways.

markII? Where's the mark1? Am I missing something?

From what i've seen on MTF charts the big difference in performance is with the new Mk III teleconverters as well as the weight reduction (the 400/2.8 shed 4lbs! supposedly the diet on the 500/4 and 600/4 is equally astounding) the new IS and focus modes as well as the new interchangeable tripod collar
