For those of you speak french, there is a brand new test in the French magazine Le Monde de la Photo http://www.lemondedelaphoto.com/-Tests,4-.html !!
In resumé, it shows that the lens is much stronger in FF than DX; in FF the piqué is just weak in the borders at 85mm f4, but closing down one stop fixes it. Distortion is a little high, but nothing that NX2 or DXO wont fix easily.
On a DX body the piqué is weak from 50mm on at F4 and you have to close down one or two stops to fix it all the way to 120mm.
Considering that this is supposed to be a FF Pro light, I am not surprised to see the same problems that Canon has with a virtually identical optics on a DX body, but it certainly looks OK on a D700 or D3, as it is supposed to be. In real life use, it certainly looks good enough for normal reportage work, allthough the pric is high. What else is new!!! <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='
