Bob has pretty much nailed it TBH.
I have recently aquired one, and yes it is bloody heavy
Especially on a 1D MKii!
But so far so good. I haven't used it much so far, but first impressions are good.
As mentioned, at 350mm it's probably not going to be as good as a 300mm 0r 400mm prime, but then I have found it pretty good considering.
At work at the mo, but if you wait until this evening I'll pop a few samples up.
Ian,
sorry pal, still no internet at home :annoyed:
