Hey Everyone,

Yes, Sigma did sent a new model out to me. I took it to Montana to Glacier and plan on taking it to Yellowstone in October. The lens is super - and I mean super - sharp. Even with tele-extenders, it is razor sharp. The focus is also super fast.

I am not seeing a green color shift to the glass -but this is something that Sigma had said they had dealt with in the new unit.

I will be posting a review shortly.

James
