Speaking (ok, 'typing') as an Australian... I find it great to hear a review by an Aussie professional!
I have heard many accents from various other countries doing pro reviews of lenses / photography gear, so this is refreshing.
Aussie Aussie Aussie... oi oi oi!!
And what Joshua says makes sense... of course it is a shame we didn't have access to all his sample shots, but as it's not a final production copy, that's probably understandable (NDA).
I doubt I'll buy this lens, even though I can afford it... but I would very much like to use it (I particularly enjoy taking photos of wildlife).
